Denial of Service in Red Hat Build of Keycloak allows unauthenticated remote attackers to exhaust server resources by submitting specially crafted POST requests with excessively long scope parameters to the OpenID Connect token endpoint. No public exploit identified at time of analysis, but CVSS 7.5 (High) with network attack vector and low complexity indicates straightforward exploitation. Authentication requirements: unauthenticated (CVSS PR:N). The vulnerability stems from improper resource management (CWE-1050), enabling attackers to cause prolonged processing times and service disruption without any authentication or user interaction.
Authorization code forgery in Red Hat Keycloak enables unauthenticated attackers to escalate privileges to admin-level access tokens. The SingleUseObjectProvider's lack of type and namespace isolation permits attackers to forge valid authorization codes remotely, though exploitation requires high complexity (AC:H). No public exploit identified at time of analysis, with CVSS 7.4 indicating high confidentiality and integrity impact but no availability disruption.
Open redirect in Red Hat Build of Keycloak allows authenticated attackers with control over another path on the same web server to bypass wildcard-based redirect URI validation and steal OAuth access tokens. Attack requires low complexity and user interaction (CVSS 7.3). EPSS and KEV status not available; no public exploit identified at time of analysis. This CWE-601 flaw enables token theft through maliciously crafted redirect flows, posing significant risk to SSO deployments where Keycloak shares a web server with attacker-controllable content.
Remote denial of service via integer overflow in Corosync cluster engine affects Red Hat Enterprise Linux 7-10 and OpenShift Container Platform 4. Unauthenticated attackers can send crafted UDP packets to crash Corosync services running in totemudp/totemudpu mode (CVSS 7.5, AV:N/PR:N). EPSS data not provided; no public exploit identified at time of analysis. Impacts high-availability cluster deployments where Corosync provides quorum and messaging services.
Out-of-bounds read in Corosync allows unauthenticated remote attackers to crash cluster nodes and potentially leak memory via malformed UDP packets. Affects default totemudp/totemudpu configurations across Red Hat Enterprise Linux 7/8/9/10 and OpenShift Container Platform 4. CVSS 8.2 (High) with network attack vector, low complexity, and no authentication required. EPSS and exploitation status data not available; no public exploit identified at time of analysis. Impacts high-availability clustering infrastructure commonly used in enterprise production environments.
Heap-based buffer overflow in gdk-pixbuf's JPEG image loader enables remote denial of service through malformed JPEG images without user interaction. The vulnerability triggers during automated image processing operations like thumbnail generation across Red Hat Enterprise Linux 6 through 10, allowing unauthenticated network attackers to crash applications that process JPEG images. EPSS score of 0.09% (25th percentile) suggests low observed exploitation activity, consistent with SSVC assessment showing no active exploitation despite the vulnerability being fully automatable.
Remote code execution in libarchive on 32-bit systems allows unauthenticated attackers to execute arbitrary code via specially crafted ISO9660 images. The vulnerability affects Red Hat Enterprise Linux versions 6 through 10 and OpenShift Container Platform 4, with vendor patches released across multiple RHSA advisories. Despite the CVSS 7.5 score and network attack vector, EPSS exploitation probability is low (0.05%, 16th percentile) and no public exploit is identified at time of analysis, though SSVC classifies the vulnerability as automatable with total technical impact.
HTTP request smuggling in Undertow (the embedded web server underpinning JBoss EAP, Red Hat Data Grid, and Apache Camel for Spring Boot) allows remote unauthenticated attackers to bypass front-end security controls by prepending whitespace to header lines. Undertow strips leading spaces from the first header line in violation of RFC 7230, creating a parser discrepancy between upstream proxies and the application server. No public exploit identified at time of analysis, and EPSS sits at 0.13% (32nd percentile), but the CVSS 9.1 and broad Red Hat middleware exposure make this a high-value target for chained attacks.
HTTP request smuggling in Undertow allows remote unauthenticated attackers to send `\r\r\r` as a header block terminator, which can desynchronize parsing when Undertow sits behind specific intermediaries such as older Apache Traffic Server or Google Cloud Classic Application Load Balancer. The flaw affects numerous Red Hat distributions of Undertow (JBoss EAP 7/8, Data Grid 8, Fuse 7, Camel for Spring Boot 4, RHEL 8/9/10) and carries a CVSS 9.1, though EPSS is only 0.04% and there is no public exploit identified at time of analysis.
HTTP request smuggling in Red Hat Undertow allows remote unauthenticated attackers to bypass front-end security controls by exploiting parsing discrepancies between Undertow and upstream proxies when handling crafted header names. The flaw (CWE-444) affects Undertow embedded in multiple Red Hat products including JBoss EAP 7/8, Data Grid 8, Fuse 7, and Apache Camel for Spring Boot 4, with Red Hat issuing patches via RHSA-2026:25125 and RHSA-2026:25126. There is no public exploit identified at time of analysis and EPSS is low (0.10%), but CVSS 9.1 and SSVC 'total' technical impact warrant prompt patching of internet-facing deployments.
Remote denial-of-service in libssh 0.11.x and earlier allows unauthenticated attackers to crash SSH server daemon processes via malformed GSSAPI authentication OID payloads. The vulnerability affects the ssh_get_hexa() API function when processing zero-length input, exploitable remotely when GSSAPI authentication is enabled and logging verbosity is set to SSH_LOG_PATCH (level 3) or higher. Red Hat, Ubuntu, SUSE, and Debian have released patches (libssh 0.11.4 and 0.12.0). EPSS score of 0.09% and SSVC assessment indicate low real-world exploitation likelihood despite network attack vector, with no active exploitation confirmed. Ubuntu classified this as low priority, and CISA SSVC notes exploitation as 'none' but 'automatable' with partial impact.
Denial of service in p11-kit's PKCS#11 RPC client allows a malicious remote token to trigger a NULL pointer dereference or undefined behavior in applications consuming derive-key operations. The flaw is reachable when an application calls C_DeriveKey against a remote token using IBM Kyber or IBM BTC derive mechanisms whose parameters are NULL, with the RPC client returning an uninitialized value. EPSS is low (0.10%) and no public exploit identified at time of analysis; SSVC marks exploitation as none but automatable.
Remote code execution is achievable in Red Hat Foreman and Satellite 6 via command injection in the WebSocket proxy implementation when users access VM VNC console functionality. An attacker controlling a malicious compute resource server can inject unsanitized hostname values into shell commands, compromising the Foreman server and potentially the entire managed infrastructure. A proof-of-concept exploit exists according to SSVC data, elevating real-world risk despite requiring low-privileged authentication and user interaction.
Heap buffer over-read in GIMP's PCX image loader allows a remote attacker who can convince a user to open a crafted PCX file to disclose adjacent heap memory and crash the application. The flaw stems from an off-by-one error (CWE-193) and is tracked across Red Hat Enterprise Linux 6 through 9. No public exploit identified at time of analysis and EPSS is very low (0.06%, 19th percentile), with CISA SSVC rating exploitation as 'none'.
A signed integer overflow vulnerability exists in the libtiff library's putcontig8bitYCbCr44tile function that leads to out-of-bounds heap writes through incorrect memory pointer calculations. Red Hat Enterprise Linux versions 6, 7, 8, 9, and 10 are confirmed affected. An attacker can exploit this by tricking a user into opening a specially crafted TIFF file, potentially achieving arbitrary code execution or causing application crashes.
The antchfx/xpath component in Debian is vulnerable to denial of service when processing specially crafted Boolean XPath expressions, which trigger an infinite loop in the logicalQuery.Select function consuming 100% CPU resources. Unauthenticated remote attackers can exploit this over the network without user interaction to disable affected systems. No patch is currently available.
The Feast Feature Server contains a path traversal vulnerability in its `/read-document` endpoint that allows unauthenticated remote attackers to read arbitrary files accessible to the server process, including sensitive system files, application configurations, and credentials. Red Hat OpenShift AI (RHOAI) deployments are confirmed affected across multiple versions. The vulnerability is rated 7.5 (High) with network-based exploitation requiring no authentication or user interaction, though no active exploitation (KEV) or public proof-of-concept is currently documented.
Heap memory disclosure in libarchive allows remote unauthenticated attackers to read sensitive heap data by submitting a malformed RAR archive. The flaw affects Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4, with vendor patches available per multiple RHSA advisories (RHSA-2026:8492 through RHSA-2026:8908). Despite the HIGH CVSS score of 7.5 and network-exploitable vector requiring no authentication, the EPSS score of 0.14% (35th percentile) indicates low observed exploitation probability. No public exploit code identified at time of analysis, and not listed in CISA KEV, suggesting this remains a patch-and-monitor priority rather than emergency response.
Keycloak contains an authentication bypass vulnerability in its SAML broker functionality that allows remote attackers with low-level privileges to complete IdP-initiated broker logins even when the SAML Identity Provider has been administratively disabled. Red Hat Build of Keycloak versions 26.2 and 26.4 are affected, with patches available in versions 26.2-16, 26.2.14-1, 26.4-12, and 26.4.10-1. The CVSS score of 8.1 reflects high confidentiality and integrity impact, though no evidence of active exploitation (KEV) or public proof-of-concept has been reported at this time.
Keycloak's SAML broker endpoint contains a validation flaw that allows attackers with a valid signed SAML assertion to inject encrypted assertions for arbitrary principals when the overall SAML response is unsigned. This leads to authentication bypass and unauthorized access to protected resources. Red Hat build of Keycloak versions 26.2 and 26.4 are affected, with patches available in versions 26.2-16, 26.2.14-1, 26.4-12, and 26.4.10-1. No evidence of active exploitation (not in CISA KEV) has been reported.
Information disclosure and denial-of-service in GNU Binutils' BFD linker (ld) arises from an out-of-bounds heap read when parsing malformed XCOFF object files. A local attacker who convinces a user to link or otherwise process a specially crafted XCOFF file can leak adjacent heap memory (CWE-125) or crash the linking process. Tracked by Red Hat across RHEL 6 through 10 and OpenShift 4; no public exploit is identified and EPSS exploitation probability is negligible (0.01%, 2nd percentile).
Out-of-bounds heap read in the BFD linker (ld) component of GNU Binutils allows information disclosure or an application-level crash when a victim is induced to process a crafted XCOFF object file. Affected across Red Hat Enterprise Linux 6 through 10 (and OpenShift Container Platform 4), exploitation requires user interaction and local file processing - there is no public exploit identified at time of analysis, and the EPSS probability is negligible (0.01%, 2nd percentile).
Infinite loop in libarchive's RAR5 decompression (archive_read_data) allows remote unauthenticated denial-of-service via malformed archive that passes checksum validation. Affects Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4. EPSS 0.04% (11th percentile) suggests low exploitation probability despite CVSS 7.5. Vendor patches available from Red Hat and Ubuntu. Upstream fix in libarchive PR#2877. No active exploitation confirmed (not in CISA KEV).
Keycloak's first broker login flow leaves a temporary account-linking proof behind after a federated identity link is established or manually removed (CWE-613), allowing an attacker who controls the external identity to silently re-establish the link and authenticate as the victim without any further confirmation. The flaw affects Red Hat Build of Keycloak and Red Hat Single Sign-On 7 deployments that use identity brokering, and carries high confidentiality and integrity impact despite a moderate CVSS base of 6.4. No public exploit code was identified at time of analysis and the issue is not listed in CISA KEV.
A path-handling flaw in the containers/storage Go library lets a crafted tar archive containing a malicious whiteout entry (for example 'victim/.wh.') cause UnpackLayer, ApplyLayer, or ApplyUncompressedLayer to replace the extraction destination directory with an arbitrary file. Systems that unpack container image layers with this library — notably Red Hat Enterprise Linux 10, Red Hat Ansible Automation Platform 2, OpenShift Container Platform 4, Quay 3, OpenShift Virtualization, Dev Spaces, and Red Hat Hardened Images — are in scope. Exploitation requires the operator or process to unpack an attacker-supplied archive, and the integrity impact is confined to the local extraction target; no public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, consistent with the modest CVSS 3.1 base score of 4.4.
GNOME Shell fails to validate the declared dimensions of icons returned by a remote search provider over D-Bus against the actual icon data buffer, producing an out-of-bounds read when an oversized size is supplied. A malicious or compromised search provider registered in a user's session can crash the shell — terminating the desktop session — and may leak fragments of adjacent shell memory. Rated CVSS 6.1 (AV:L/UI:R/C:L/A:H) by Red Hat; no public exploit code or CISA KEV entry was identified at time of analysis, so exploitation currently requires a locally present hostile search provider rather than remote access.
Confused deputy exploitation in hawtio-operator on OpenShift allows a namespace-scoped edit user to claim arbitrary externally-routable Route hostnames that would normally require elevated cluster permissions. The operator holds a cluster-wide `routes/custom-host:create` privilege and blindly propagates the tenant-controlled `spec.routeHostName` field from Hawtio custom resources into OpenShift Route specs without validating whether the requesting user is authorized to claim that hostname. The captured subdomain can then be combined with the cluster's auto-grant OAuthClient to hijack OAuth redirect flows and steal tokens from legitimate users (PR:L, UI:R, C:H, CVSS 6.3). No public exploit code has been identified at time of analysis.
Denial of service in multipathd allows a local attacker with access to the UNIX control socket to permanently block the daemon's listener thread by sending valid commands and then refusing to read the replies. This renders legitimate IPC operations - such as multipath path queries and storage management commands - unable to complete until the daemon is restarted. Red Hat, the reporting source, explicitly confirms the issue is bounded to availability impact only: no privilege escalation, no code execution, and no confidentiality or integrity loss. No public exploit code has been identified at time of analysis.
Heap buffer overflow in the libtiff `tiff2pdf` utility allows local attackers to cause severe memory corruption and application crashes by supplying a crafted BigTIFF file. The root cause is an integer truncation: a 64-bit `StripByteCounts` value is silently narrowed to 32 bits, producing an undersized heap allocation that a subsequent memory copy overflows. Red Hat has issued advisory RHSA-2026:53467 and an upstream fix is available via libtiff GitLab merge request #729; no public exploit or active exploitation has been identified at time of analysis.
Keycloak's Dynamic Client Registration endpoint exposes confidential client secrets in cleartext to users holding the view-clients realm management role, violating the principle of least privilege. Affected deployments include Red Hat Build of Keycloak and Red Hat Single Sign-On 7 across all tracked versions. An attacker granted only read-only view-clients access can harvest any confidential OAuth/OIDC client secret via the registration API and subsequently authenticate as that client, escalating their effective permissions within the realm to whatever the compromised client is authorized to do.
Symlink-following in libvirt's qemuTPMEmulatorPrepareHost() allows a local attacker with access to the swtpm service account to redirect a path-based chown() call - executed by libvirtd running as root - to transfer ownership of any arbitrary file on the system to the swtpm user. This affects libvirt on Red Hat Enterprise Linux 6 through 10. With ownership of a sensitive file such as /etc/shadow or a cron directory transferred to swtpm, the attacker gains a privilege escalation primitive beyond the swtpm account boundary. No public exploit or active exploitation has been identified at time of analysis.
Integer overflow in GStreamer's gst-plugins-good isomp4 plugin exposes adjacent heap memory when parsing CEA-608 closed-caption data embedded in specially crafted MP4 or MOV files. The 32-bit unsigned arithmetic wraparound bypasses a bounds check, enabling an out-of-bounds heap read of up to 244 bytes that is forwarded into downstream caption output - leaking process memory to an attacker who controls caption rendering output. Affected platforms include Red Hat Enterprise Linux 6 through 10; no public exploit has been identified at time of analysis, and no active exploitation is confirmed.
JavaScript injection in Evolution email client allows a remote, unauthenticated attacker to execute arbitrary JavaScript within the mail-viewing context by sending a specially crafted HTML email containing a spoofed vCard control. When the victim clicks the vCard control, Evolution's trusted JavaScript handler incorrectly places an attacker-controlled javascript: URL into an iframe's src attribute, bypassing Evolution's own script-execution protections for email content. The vulnerability is classified CWE-84 (improper neutralization of encoded URI schemes), and exploitation requires one user interaction gesture - clicking the vCard element - making it realistic against any Evolution user on a RHEL or GNOME desktop. No public exploit code or CISA KEV listing has been identified at time of analysis.
Pacemaker Configuration System (PCS) on Red Hat Enterprise Linux 8, 9, and 10 exposes an arbitrary file-read primitive to local members of the 'haclient' group via the `pcs host auth --token` command. The pcsd daemon reads the attacker-specified file path with root privileges, base64-encodes up to 256 bytes of content, and transmits it through cluster node communication channels the attacker controls - enabling exfiltration of short sensitive files such as API tokens, symmetric keys, or credential snippets that are otherwise inaccessible to the attacker. No public exploit has been identified at time of analysis, but the attack requires only local access and group membership, making it a realistic insider-privilege escalation threat in multi-tenant HA environments.
Symlink-following in crun's container runtime allows a low-privileged container user to redirect stdio file descriptors to host files and alter their ownership. Affecting crun 1.29.1 and earlier, the flaw manifests when crun reopens /dev/null for stdio after pivot_root: if the container's /dev/null has been replaced with a symlink to a host path, crun resolves the symlink outside the container namespace and chowns the target file to the container UID. No vendor-released patch is available at time of analysis. No public exploit identified at time of analysis.
Integrity escape in crun 1.29.1 and earlier allows a low-privileged local attacker to redirect /dev/console to an attacker-controlled filesystem path, breaking container boundary isolation. The flaw (CWE-59, improper link resolution) triggers during terminal setup when a container configuration omits a dedicated /dev mount, including via the read-only-rootfs bind-mount fallback path, resulting in a scope-changed integrity impact on the host. No vendor-released patch exists at time of analysis, and no public exploit has been identified.
Keycloak's Device Authorization Grant flow (RFC 8628) fails to enforce brute-force account lockout during token redemption, allowing an attacker holding an active device authorization session for a locked account to complete the flow and obtain valid access and refresh tokens. Affected deployments include Red Hat Build of Keycloak and Red Hat Single Sign-On 7 across all versions flagged in the CPE data. No public exploit code or CISA KEV listing has been identified at time of analysis, but the flaw silently undermines a core security control intended to stop credential-stuffing and persistent account compromise.
Uncontrolled recursion in Red Hat Service Interconnect 2's skupper-router AMQP field parser allows a remote unauthenticated attacker to crash the router by sending a specially crafted network message, resulting in denial of service for all services relying on the interconnected network. The vulnerability stems from an absent recursion depth limit during AMQP message parsing, causing stack memory exhaustion. No public exploit code has been identified at time of analysis, and the CVSS AC:H rating reflects the need to craft a payload that precisely triggers the unbounded recursion path.
Case-insensitive username comparisons in two code paths of the CUPS scheduler - printer ACL validation and private-attribute filtering - allow an authenticated adjacent-network attacker to bypass username-based access controls in configurations that rely on those ACLs. The bypass exposes private print attributes to users who should be excluded by ACL policy. Affected deployments span Red Hat Enterprise Linux 6 through 10, Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation has been identified at time of analysis, consistent with the low CVSS base score of 3.0.
Unconditional TLS certificate validation disabling in the OCAPI modules (ocapi_command, ocapi_info) of the community.general Ansible collection exposes HTTP Basic-Auth credentials to interception and permits response tampering against any managed OCAPI storage or enclosure device. Because the shared request helper disables certificate validation on every call with no parameter to re-enable it, a network-adjacent attacker performing a MITM attack can present any certificate, silently capture credentials, and inject falsified device responses back to the Ansible controller. Red Hat bundles the affected collection in Ceph Storage 5 and 9 and OpenStack Platform 17.1 and 18.0; no public exploit has been identified at time of analysis.
Heap out-of-bounds read in CUPS's cupsUTF32ToUTF8() transcoding function exposes partial daemon heap memory to adjacent-network attackers without authentication. The vulnerable code path is reachable via SNMP supply-description parsing, meaning any attacker who can spoof or inject crafted SNMP responses on the same network segment as a CUPS host can trigger the read and potentially leak heap contents from the printing daemon. No active exploitation has been identified, and the adjacent-network attack vector significantly limits the exposure surface.
Path traversal in the key provider component of Red Hat Build of Keycloak allows a realm administrator to probe arbitrary filesystem paths by supplying crafted keystore parameters, revealing the existence and readability of server-side files. The vulnerability exists because a prior fix for path probing was incomplete, leaving a residual bypass in the keycloak-services library - the core engine shared by both Red Hat Build of Keycloak and Red Hat Single Sign-On 7. No public exploit code has been identified at time of analysis, and exploitation requires realm administrator credentials, materially limiting opportunistic attack surface.
Symlink-following race condition in GLib2's g_file_replace() allows a local attacker with write access to the destination directory to redirect privileged file writes to arbitrary files. When the G_FILE_CREATE_REPLACE_DESTINATION flag is set and creation of the .goutputstream-XXXXXX temporary file fails, GLib2 unlinks the destination and then recreates it without O_EXCL (exclusive creation) or symlink-safe open semantics, opening a TOCTOU race window. An attacker who wins this race by placing a symlink at the destination path can cause any process using this code path - potentially running with elevated privileges - to overwrite files the attacker cannot directly modify. No public exploit has been identified at time of analysis.
Unauthenticated-read path exposure in the odh-dashboard component of Red Hat OpenShift AI allows any valid dashboard user to retrieve full Kubernetes Secret objects - including the cluster NVIDIA NGC API key (apiKeySecret) and NIM image pull secret (nimPullSecret) - via GET /api/nim-serving/:nimResource without an authorization check. The route uses the dashboard's elevated service account to proxy Kubernetes API calls, bypassing the admin-gating that protects the equivalent create and delete operations on the same NIM credentials. Affected organizations risk unauthorized access to NVIDIA NGC cloud services and private container registries under their accounts. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Flatpak's `org.freedesktop.Flatpak.SystemHelper` D-Bus service contains a TOCTOU race condition in the `Deploy()` function where a privileged `chmod` executes before OSTree repository validation completes, allowing a local low-privileged attacker to redirect symlinks to arbitrary system files within that timing window. A successful exploit can yield high-confidentiality impact (reading privileged files) and limited integrity and availability impact (CVSS C:H/I:L/A:L), as the unguarded chmod can be inherited by attacker-controlled symlink targets. No public exploit code or CISA KEV listing has been identified at time of analysis, and the High attack complexity (AC:H) reflects the precision timing required to win the race.
Heap out-of-bounds read in libtpms during TPM 2.0 state restoration allows an adjacent unauthenticated attacker to crash the swtpm process and deny TPM services to dependent virtual machines. The flaw arises in the state-blob parser: an attacker-controlled oversized skip-block length drives the internal INT32 size counter negative; subsequent bounds checks cast that counter to UINT32, wrapping it to a large positive value and bypassing the check, which then drives the parser to read memory outside the heap buffer. Vendor and upstream commit confirm the impact is denial of service only - no data corruption or information disclosure was confirmed. No public exploit or CISA KEV listing has been identified.
HTTP/2 flow-control window mismanagement in libsoup (GNOME's HTTP client/server library) allows a malicious HTTP/2 server to abort a connecting client process or crash its HTTP/2 session. When the client sends a request body sourced from a non-pollable GInputStream, libsoup buffers the data before transmission; a server that then shrinks SETTINGS_INITIAL_WINDOW_SIZE causes the client to copy the full pre-buffered payload into a now-undersized DATA callback without a runtime bounds check, triggering a reachable assertion abort (CWE-617). No public exploit has been identified at time of analysis, and the high-complexity timing requirement constrains practical exploitation.
Integer overflow in Corosync's membership commit token processing crashes the daemon on 32-bit cluster nodes, enabling a denial-of-service attack from any adjacent network host. The CWE-190 flaw causes the length validation to be bypassed on 32-bit systems where arithmetic wraps before the bounds check is applied, resulting in an out-of-bounds memory access that kills the Corosync process. Modern 64-bit deployments of the same packages are explicitly not affected, substantially narrowing real-world exposure despite the CVSS 6.5 rating; no public exploit code or CISA KEV listing exists at time of analysis.
Key-ID (kid) bypass in the jwcrypto Python JOSE library allows an attacker who holds any valid key within a JWK set to forge a General JSON Serialization JWS that satisfies verification for a different kid, effectively impersonating another tenant, user, or service. Affected deployments include Red Hat Ansible Automation Platform 2, RHEL 7-10, Red Hat OpenShift AI (RHOAI), and Red Hat OpenStack Platform 16.2, wherever jwcrypto performs JWS signature verification with kid-based authorization. No public exploit or CISA KEV listing has been identified at time of analysis, and the EPSS score is not provided, but the integrity impact is high for multi-tenant architectures.
Stack exhaustion in gfs2-utils's metawalk.c metadata walk code allows a local attacker to cause denial of service by supplying a crafted GFS2 filesystem image containing a maliciously large inode height value that drives unbounded alloca() calls. Affected systems include Red Hat Enterprise Linux 7, 8, and 9 with gfs2-utils installed; the CVSS 4.7 medium rating reflects a local, high-complexity, user-interaction-required attack path with no confidentiality or integrity impact. No public exploit code or active exploitation has been identified at time of analysis.
Heap out-of-bounds read in gfs2-utils enables memory disclosure and potential crashes when parsing crafted GFS2 filesystem images. The `ea_num_ptrs` field embedded in on-disk extended attribute metadata is consumed without validating it against the available buffer boundary, allowing an attacker who controls a filesystem image to trigger a heap over-read. Affected across Red Hat Enterprise Linux 7, 8, and 9; no public exploit is identified at time of analysis, and the local, user-interaction-dependent attack vector substantially limits practical exploitation.
Stack exhaustion in gfs2-utils allows an attacker who can deliver a crafted GFS2 filesystem image to crash fsck.gfs2, gfs2_edit, or savemeta on Red Hat Enterprise Linux 7, 8, and 9. The root cause is unbounded use of alloca() in metawalk.c's hash table traversal, where the allocation size is derived exponentially from the on-disk di_depth field with no upper-bound check, so a sufficiently large di_depth value causes the process stack to be fully consumed. The impact is limited to denial of service of the affected utility; no public exploit has been identified at time of analysis, and EPSS data is not available in the provided intelligence.
Crash of the gvfsd-mtp daemon in gvfs is achievable by anyone who can connect a malicious USB MTP device to a target Linux system. The do_read() function in gvfsbackendmtp.c accepts the byte-count reported by the device at face value and passes it uncapped to memcpy(), causing an out-of-bounds read that triggers a segmentation fault when the device deliberately over-reports its response length. The vulnerability affects gvfs as packaged across Red Hat Enterprise Linux 6 through 10; no public exploit has been identified and exploitation is constrained by physical proximity.
Heap buffer overflow in the gvfs AFP (Apple Filing Protocol) backend allows a malicious AFP server to crash the gvfsd-afp process on connecting clients, resulting in denial of service. When a client mounts an AFP share, the DSI (Data Stream Interface) read path accepts a server-supplied length value without validating it against the pre-allocated reply buffer, enabling the server to write past buffer boundaries. This affects RHEL 6 through 10 and requires user interaction to mount a malicious share; no public exploit or CISA KEV listing has been identified at time of analysis.
Uninitialized heap memory disclosure in gvfs's SFTP backend enables a malicious SFTP server to deterministically defeat ASLR on client systems running RHEL 6 through 10. When a user mounts a crafted SFTP share, the read_string() parser allocates a buffer for the FXP_HANDLE response but does not verify that the buffer is fully populated; the client subsequently echoes the uninitialized remainder - containing heap base pointers and the libgio load address - back to the attacker on every subsequent file-handle request. No public exploit has been identified at time of analysis, and the issue does not appear in CISA KEV, but the ASLR bypass it achieves is a high-value precursor for chained memory-corruption attacks against gvfsd-sftp.
Stored cross-site scripting in pulpcore's content serving layer allows authenticated users with file upload permissions to execute arbitrary JavaScript in the browsers of other users. When pulpcore uses local filesystem storage, uploaded files are served with their original MIME types (e.g., text/html, image/svg+xml) and without a Content-Disposition: attachment header, causing browsers to render the files inline within the host application's origin instead of prompting a download. This flaw affects Red Hat Ansible Automation Platform 2, Red Hat Satellite 6, and Red Hat Update Infrastructure 4 and 5; no public exploit code or confirmed active exploitation is identified at time of analysis.
Unauthenticated enumeration of internal PKI topology is possible in Red Hat Certificate System 9 through an unprotected REST endpoint. Any network-accessible client can issue GET /ca/rest/securityDomain/hosts and receive a structured inventory of all participating CA subsystem hosts, their roles, and security domain membership - without presenting credentials, a client certificate, or a session token. While the direct CVSS impact is rated medium (5.3), the real-world significance lies in enabling precise reconnaissance of internal PKI infrastructure that could facilitate targeted follow-on attacks against specific subsystems. No active exploitation is confirmed and no public exploit code has been identified at time of analysis.
Unauthenticated network attackers can elicit Java stack traces from Red Hat IdM's Dogtag CA REST enrollment endpoint (POST /ca/rest/certrequests) by submitting malformed requests, causing HTTP 500 responses that expose internal implementation details under CWE-209. The same error path simultaneously amplifies the CA debug log with large multi-line stack traces, creating a log-fill resource exhaustion vector that drives disk growth and I/O contention on affected RHEL 6 through 10 deployments. No public exploit has been identified at time of analysis, but the attack requires no authentication and low complexity, making it accessible to unskilled opportunistic attackers targeting IdM infrastructure.
Heap metadata corruption in the popt command-line parsing library's `poptConfigFileToString` function can be triggered by a local, low-privileged attacker who supplies specially crafted configuration file content to an affected host. Successful exploitation causes the consuming process to crash, resulting in denial of service. CVSS 2.5 (Low) reflects the strictly local, high-complexity exploitation path with no confidentiality or integrity impact; no public exploit code or active exploitation (CISA KEV) is known at time of analysis.
Heap out-of-bounds read and stack out-of-bounds access in GIMP's file-psd plugin allow an attacker to crash the application or disclose limited memory contents by convincing a user to open a specially crafted PSD image. The flaw affects GIMP as shipped in Red Hat Enterprise Linux 6 through 9 and stems from missing validation of the channel-count parameter during PSD parsing. No active exploitation has been identified; the attack requires local file delivery and deliberate user interaction, significantly constraining real-world risk.
Heap out-of-bounds read in GIMP's file-pvr plugin exposes users of Red Hat Enterprise Linux 6 through 9 to application crashes and limited heap memory disclosure when opening a crafted PVR image file. The VQ (Vector Quantization) compressed-texture decoder omits mandatory bounds validation, allowing a malicious image to read beyond allocated heap regions. Impact is primarily denial of service via crash, with a secondary low-severity information disclosure path; no public exploit code and no CISA KEV listing are associated with this issue at time of analysis.
Heap out-of-bounds read in GIMP's file-ico plugin allows a local attacker to crash GIMP or leak limited heap memory contents by delivering a specially crafted ICO image file to a victim user. Affected packages span Red Hat Enterprise Linux 6 through 9. No public exploit code or CISA KEV listing exists at time of analysis, but the user-interaction requirement (opening a malicious file) is the primary delivery mechanism and a realistic social-engineering target in image-processing workflows.
Out-of-bounds memory write in libsolv crashes RPM-based package manager tools (dnf, yum, zypper) when processing a corrupted or specially crafted .solv repository cache file. The root cause is an absent array-index bounds check on directory-id values read from compressed filelist data during .solv file rewriting - but because the out-of-bounds write stores only a fixed, non-attacker-controlled value, the vendor explicitly rules out arbitrary code execution, confining impact to denial of service. No public exploit has been identified and no active exploitation is confirmed; note that the 'RCE' metadata tag conflicts directly with the description and appears to be erroneous.
Heap out-of-bounds read in GIMP's file-iff plugin allows a local attacker to crash the application or disclose limited heap memory contents by delivering a specially crafted IFF/ILBM image file. The flaw stems from missing validation of HAM row size when the number of color planes (nPlanes) is zero, causing a size mismatch that bypasses memory bounds checking. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis.
Heap buffer overflow in FFmpeg's TDSC screen-capture codec decoder exposes Red Hat Enterprise Linux AI 3 and OpenShift AI deployments to denial of service or potential arbitrary code execution. The tdsc_load_cursor() function performs erroneous stride-based pointer arithmetic in two locations when rendering cursor data from crafted TDSC video, writing past a heap-allocated buffer boundary. No public exploit or active exploitation has been confirmed at time of analysis, and the upstream fix is available as FFmpeg commit 242ff799c.
Denial of service in jwcrypto's JWE.deserialize() function allows a remote unauthenticated attacker to crash any service that processes untrusted JWE tokens by submitting a malformed compact serialization containing an excessive number of period delimiters, triggering uncontrolled memory allocation and a MemoryError. Affected deployments include Red Hat Ansible Automation Platform 2, RHEL 9 and 10, OpenShift AI (RHOAI), and OpenStack Platform 16.2 as disclosed via Red Hat Bugzilla 2524147 and upstream advisory GHSA-96rv-c4vc-h4f4. No public exploit code or CISA KEV listing exists at time of analysis, and impact is confined to availability with no confidentiality or integrity exposure.
Out-of-bounds write in gdk-pixbuf's JPEG decoder affects any application on Red Hat Enterprise Linux 6 through 10 that renders JPEG images containing chunked ICC profile markers. When ICC profile parsing encounters an error, stale size metadata persists after the profile buffer is freed; a subsequent allocation within the same decode operation then writes beyond buffer boundaries, crashing the application. No active exploitation has been identified (no CISA KEV listing), and no public exploit code is known at time of analysis, but the availability-only impact and user-interaction requirement make this a realistic denial-of-service risk in desktop and server image-processing contexts.
Cross-organization IDOR in Katello's Content View Filter Rules API allows authenticated low-privileged users to access and modify filter rules belonging to Content View Filters in other organizations by supplying a foreign filter identifier. Red Hat Satellite 6 deployments running multi-organization configurations are affected, as the API enforces authorization on the Content View but fails to validate the parent Content View Filter's organizational boundary. No public exploit code or active exploitation has been identified at time of analysis, and the CVSS score of 5.4 (Medium) reflects the limited scope - authenticated access and Satellite's enterprise context constrain real-world exposure.
Foreman's template revision endpoint, as shipped in Red Hat Satellite 6, exposes historical template contents across organizational and location boundaries due to missing object-level authorization (IDOR/BOLA, CWE-639). An authenticated user holding any template-related permission - as minimal as view_ptables - can retrieve audit-history revisions owned by other organizations simply by supplying a guessable audit ID. Template revisions may contain credentials, secrets, or sensitive configuration data, making the confidentiality impact high despite the low attack complexity. No public exploit has been identified at time of analysis, though the low-privilege entry bar lowers the practical exploitation threshold significantly.
Stack-based denial of service in GIMP's Seattle FilmWorks (SFW) image plugin crashes the application when a crafted SFW file triggers an unbounded variable-length array allocation on the stack. The flaw affects all GIMP versions per the GNOME CPE string and is confirmed across Red Hat Enterprise Linux 6 through 9. An attacker who can deliver a malicious SFW file to a user can reliably crash the GIMP process with no code execution or data exposure; no public exploit has been identified at time of analysis.
Cross-organizational information disclosure in Katello - the content management engine of Red Hat Satellite 6 - allows any authenticated user to read lifecycle history of Content Views belonging to organizations other than their own. By supplying an arbitrary Content View identifier to the Content View History API endpoint, a low-privileged user bypasses organization-scope authorization and retrieves publication events, promotion history, associated usernames, and timestamps for foreign tenants. No public exploit has been identified at time of analysis, and no CISA KEV listing exists; the CVSS 4.3 Medium rating reflects the strictly read-only, single-organization-boundary impact.
Heap out-of-bounds read in GIMP's file-xwd plugin allows a crafted XWD image file to trigger an application crash or leak partial heap memory contents into the rendered image output. Users running GIMP on Red Hat Enterprise Linux 6 through 9 are affected when they open a malicious XWD file; the plugin fails to cross-validate image width and bytes-per-line parameters against the allocated buffer size, permitting an out-of-bounds read. No public exploit is identified at time of analysis and the vulnerability is not listed in CISA KEV, placing real-world urgency in the low-to-moderate range.
CPU exhaustion in libsoup's HTTP Range header processing affects any SoupServer deployment carrying the CVE-2025-32907 fix but not MR !550. Supplying a Range header with approximately 25,000 repeated satisfiable byte ranges triggers an O(N²) coalescing loop - each g_array_remove_index() call induces an O(N) memmove on GArray - blocking the server's event loop for roughly 90 ms per request from a single unauthenticated client. The description explicitly rules out memory corruption and information disclosure; this is a pure availability issue with no public exploit identified at time of analysis.
Server-side request forgery in galaxy_ng, the Ansible Galaxy server plugin for Pulp, allows authenticated users holding namespace management permissions to redirect a background worker process into probing arbitrary internal network addresses, including loopback interfaces and cloud instance metadata endpoints (e.g., 169.254.169.254). The dual-impact vulnerability enables both internal network reconnaissance (enumerating reachable IPs and reading service responses) and a denial-of-service condition against background workers due to the absence of an HTTP client timeout. No public exploit has been identified at time of analysis, and no confirmed KEV listing exists; however, the scope-changing CVSS vector (S:C) reflects that impact crosses trust boundaries from the application into adjacent internal infrastructure.
Resource exhaustion via crafted SASL UNBIND in 389 Directory Server (389-ds-base) allows a remote authenticated attacker to stall connections and deny LDAP service to legitimate users. Affected deployments span Red Hat Directory Server 11, 12, and 13, plus 389-ds-base as packaged across RHEL 6 through 10. No public exploit code or CISA KEV listing has been identified at time of analysis, though the CVSS 6.5 rating (AV:N/AC:L/PR:L) indicates low-complexity network exploitation requiring only a low-privilege LDAP bind - a realistic bar in any environment with shared directory users.
Stack buffer overflow in file-roller's archive extraction path causes denial of service when a victim opens or extracts a crafted 7z or RAR archive containing an excessively long file path entry. The unbounded string copy in the progress-line parsing routine overwrites a fixed-size stack buffer, crashing the application with no confidentiality or integrity impact. No public exploit code or CISA KEV listing has been identified at time of analysis, and exploitation is gated entirely on user interaction with a malicious archive.
CRI-O's container-creation code path crashes the daemon with an unrecovered Go runtime panic when processing an OCI image whose config.Env contains a malformed entry lacking an '=' character, under the specific condition that the CreateContainer request supplies a nil CRI Envs field. The crash terminates the crio daemon process, disrupting all container workloads on the affected node until the service is manually restarted - a node-wide denial of service. Affecting Red Hat OpenShift Container Platform 4, this requires high privileges (PR:H) to exploit; no public exploit code or CISA KEV listing has been identified at time of analysis.
Stack exhaustion and a bounded memory over-read in GIMP's file-pix (ESM) plugin allow a crafted PIX image to crash the application and leak 21 bytes of stack memory into an intermediate file. Users running GIMP on Red Hat Enterprise Linux 6 through 9 are affected when opening untrusted PIX format images. No public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis, though the DoS impact is reliable and the delivery vector - a malicious image file - is realistic for desktop users.
Improper certificate validation in JSS (Java Security Services) allows the JSSTrustManager class to accept CA certificates from the NSS database that lack TRUSTED_CA trust flags, meaning certificates never explicitly designated as trust anchors can still be used to anchor TLS chains. In non-default deployments where certificate revocation checking has been disabled, this creates a viable path for a man-in-the-middle attacker to forge certificates accepted by PKI client connections, with high confidentiality and low integrity impact. No public exploit has been identified at time of analysis, and the AC:H CVSS rating reflects the meaningful attack complexity - MITM positioning plus a specific non-default configuration must both be present.
Improper access control in Lighthouse - the cross-cluster service-discovery component of Submariner shipped with Red Hat Advanced Cluster Management for Kubernetes 2 - lets an attacker who has compromised a spoke cluster inject unauthorized EndpointSlices and ServiceImports into arbitrary namespaces on peer clusters. Because the destination namespace is taken from an attacker-controlled label/annotation on the broker object, resources can be planted into privileged namespaces such as kube-system and openshift-*, enabling privilege escalation and lateral cluster compromise. Rated CVSS 9.9 with a scope change; no public exploit identified at time of analysis.
Cross-cluster MITM attacks are enabled in Red Hat Advanced Cluster Management for Kubernetes 2.x via the lighthouse service discovery component, which fails to validate IP addresses advertised in EndpointSlice objects. An attacker controlling a compromised spoke cluster can inject arbitrary IP addresses into EndpointSlices, causing lighthouse DNS resolution across all connected clusters to redirect legitimate cross-cluster service traffic to attacker-controlled endpoints. The CVSS Scope:Changed metric confirms that impact propagates beyond the compromised spoke cluster to the hub and peer clusters, enabling unauthorized interception and manipulation of inter-cluster communications. No public exploit code or CISA KEV listing has been identified at time of analysis.
Cross-cluster traffic redirection in Submariner (as shipped with Red Hat Advanced Cluster Management for Kubernetes 2) allows a malicious or compromised member cluster to hijack traffic from peer clusters by advertising a specially crafted network endpoint. Because Submariner does not validate the subnets a spoke cluster declares, an attacker-controlled cluster can claim arbitrary CIDR ranges and cause peer clusters to route all matching traffic through the attacker's tunnel, enabling information disclosure and denial of connectivity. Rated CVSS 9.9 with a changed scope, this affects the multicluster networking layer, though there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in FreeIPA's ipa-enrollment SLAPI plugin allows any authenticated LDAP client to crash the 389 Directory Server by sending a malformed extended operation. The flaw (CWE-476, null pointer dereference) is triggered by omitting the request value for the JOIN_OID in the ipa-enrollment extended operation, causing the server to dereference a null pointer and crash. No public exploit or active exploitation has been identified at time of analysis; however, the low attack complexity and network-accessible vector make this a credible threat against any RHEL Identity Management deployment.
Resource exhaustion in FreeIPA's OTP key processing path allows any low-privilege authenticated domain user to degrade the IPA authentication service. By submitting an oversized One-Time Password key, the user triggers an unbounded decode/re-encode cycle (CWE-770) that consumes excessive CPU and memory, degrading availability for all dependent systems and users. No public exploit code exists at time of analysis, and this CVE is not listed in CISA KEV; however, the AV:N/PR:L CVSS vector means any valid domain account on a network-accessible FreeIPA instance is sufficient to trigger the condition.
Integer truncation in libsoup's SoupServer Range-header comparator silently drops byte ranges from HTTP 206 Partial Content responses when the target resource exceeds approximately 2 GB. The sort_ranges() function in soup-message-headers.c narrows a 64-bit offset subtraction to a 32-bit int return value, inverting the comparator sign whenever offsets differ by more than INT_MAX, causing incorrect range sorting and silent omission of content. No public exploit code or CISA KEV listing has been identified at time of analysis; exploitation requires network access to a SoupServer instance serving files larger than ~2 GB.
Cross-cluster data integrity violation in Red Hat Advanced Cluster Management for Kubernetes 2 allows a registered and authenticated managed cluster to tamper with or delete indexed search data belonging to other clusters. The flaw resides in the delta-sync write paths of the search-indexer component, which fails to enforce cluster-scoped ownership checks before processing UPDATE and DELETE operations. With no public exploit identified at time of analysis and no CISA KEV listing, the practical risk is bounded by the requirement for an already-registered cluster credential, though the Changed scope (S:C) elevates concern in multi-tenant fleet environments where cluster isolation is an assumed security boundary.
The AdvertiseListenerImpl component in mod_cluster's core multicast UDP handler can be permanently crashed by a single crafted datagram, affecting Red Hat JBoss Enterprise Application Platform 7 and 8, JBoss Web Server 5 through 7, and Red Hat Single Sign-On 7. An unauthenticated attacker with adjacency to the mod_cluster multicast group can silently terminate the advertise listener thread, causing the affected node to stop receiving cluster topology updates until manually restarted - with no runtime indication of failure since isListening() continues returning true. No public exploit is identified at time of analysis, and this CVE is not listed in the CISA KEV catalog based on available data.
Heap overread in swtpm's SWTPM_NVRAM_CheckHeader() function allows local low-privileged users to crash the swtpm daemon and leak heap memory contents to system logs on Red Hat Enterprise Linux 8, 9, and 10. The root cause is a classic sizeof-pointer vs. sizeof-struct confusion: the guard compares buffer length against sizeof(bh) (pointer width, 8 bytes on 64-bit) rather than sizeof(*bh) (actual struct size), permitting undersized buffers to bypass validation and triggering a 2-byte heap overread on 64-bit systems or 6 bytes on 32-bit. No public exploit or CISA KEV listing has been identified at time of analysis.
Cross-cluster traffic interception in Submariner (shipped within Red Hat Advanced Cluster Management for Kubernetes 2) allows a single compromised member cluster to overwrite the endpoint records of other clusters in the mesh. Because the submariner-k8s-broker-cluster Role granted to every joined cluster carries more write access than it needs, an attacker holding one cluster's broker credentials can reroute inter-cluster tunnel traffic through attacker-controlled endpoints and mount a mesh-wide man-in-the-middle. Rated CVSS 9.9 with a scope change; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote code execution in the submariner-operator component of Red Hat Advanced Cluster Management for Kubernetes 2.x allows a cluster administrator-or any user holding RBAC permissions to modify the Submariner Custom Resource-to reference an unvalidated, attacker-controlled container image path, causing the operator to deploy and execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes. The root cause (CWE-20: Improper Input Validation) is the absence of image path sanitization or verification before the operator acts on the Submariner CR field, enabling privilege escalation beyond the user's intended cluster boundary. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the Changed Scope with full C:H/I:H/A:H impact ratings signal potential for complete cluster compromise once the high-privilege prerequisite is met.
Denial of Service in Red Hat Build of Keycloak allows unauthenticated remote attackers to exhaust server resources by submitting specially crafted POST requests with excessively long scope parameters to the OpenID Connect token endpoint. No public exploit identified at time of analysis, but CVSS 7.5 (High) with network attack vector and low complexity indicates straightforward exploitation. Authentication requirements: unauthenticated (CVSS PR:N). The vulnerability stems from improper resource management (CWE-1050), enabling attackers to cause prolonged processing times and service disruption without any authentication or user interaction.
Authorization code forgery in Red Hat Keycloak enables unauthenticated attackers to escalate privileges to admin-level access tokens. The SingleUseObjectProvider's lack of type and namespace isolation permits attackers to forge valid authorization codes remotely, though exploitation requires high complexity (AC:H). No public exploit identified at time of analysis, with CVSS 7.4 indicating high confidentiality and integrity impact but no availability disruption.
Open redirect in Red Hat Build of Keycloak allows authenticated attackers with control over another path on the same web server to bypass wildcard-based redirect URI validation and steal OAuth access tokens. Attack requires low complexity and user interaction (CVSS 7.3). EPSS and KEV status not available; no public exploit identified at time of analysis. This CWE-601 flaw enables token theft through maliciously crafted redirect flows, posing significant risk to SSO deployments where Keycloak shares a web server with attacker-controllable content.
Remote denial of service via integer overflow in Corosync cluster engine affects Red Hat Enterprise Linux 7-10 and OpenShift Container Platform 4. Unauthenticated attackers can send crafted UDP packets to crash Corosync services running in totemudp/totemudpu mode (CVSS 7.5, AV:N/PR:N). EPSS data not provided; no public exploit identified at time of analysis. Impacts high-availability cluster deployments where Corosync provides quorum and messaging services.
Out-of-bounds read in Corosync allows unauthenticated remote attackers to crash cluster nodes and potentially leak memory via malformed UDP packets. Affects default totemudp/totemudpu configurations across Red Hat Enterprise Linux 7/8/9/10 and OpenShift Container Platform 4. CVSS 8.2 (High) with network attack vector, low complexity, and no authentication required. EPSS and exploitation status data not available; no public exploit identified at time of analysis. Impacts high-availability clustering infrastructure commonly used in enterprise production environments.
Heap-based buffer overflow in gdk-pixbuf's JPEG image loader enables remote denial of service through malformed JPEG images without user interaction. The vulnerability triggers during automated image processing operations like thumbnail generation across Red Hat Enterprise Linux 6 through 10, allowing unauthenticated network attackers to crash applications that process JPEG images. EPSS score of 0.09% (25th percentile) suggests low observed exploitation activity, consistent with SSVC assessment showing no active exploitation despite the vulnerability being fully automatable.
Remote code execution in libarchive on 32-bit systems allows unauthenticated attackers to execute arbitrary code via specially crafted ISO9660 images. The vulnerability affects Red Hat Enterprise Linux versions 6 through 10 and OpenShift Container Platform 4, with vendor patches released across multiple RHSA advisories. Despite the CVSS 7.5 score and network attack vector, EPSS exploitation probability is low (0.05%, 16th percentile) and no public exploit is identified at time of analysis, though SSVC classifies the vulnerability as automatable with total technical impact.
HTTP request smuggling in Undertow (the embedded web server underpinning JBoss EAP, Red Hat Data Grid, and Apache Camel for Spring Boot) allows remote unauthenticated attackers to bypass front-end security controls by prepending whitespace to header lines. Undertow strips leading spaces from the first header line in violation of RFC 7230, creating a parser discrepancy between upstream proxies and the application server. No public exploit identified at time of analysis, and EPSS sits at 0.13% (32nd percentile), but the CVSS 9.1 and broad Red Hat middleware exposure make this a high-value target for chained attacks.
HTTP request smuggling in Undertow allows remote unauthenticated attackers to send `\r\r\r` as a header block terminator, which can desynchronize parsing when Undertow sits behind specific intermediaries such as older Apache Traffic Server or Google Cloud Classic Application Load Balancer. The flaw affects numerous Red Hat distributions of Undertow (JBoss EAP 7/8, Data Grid 8, Fuse 7, Camel for Spring Boot 4, RHEL 8/9/10) and carries a CVSS 9.1, though EPSS is only 0.04% and there is no public exploit identified at time of analysis.
HTTP request smuggling in Red Hat Undertow allows remote unauthenticated attackers to bypass front-end security controls by exploiting parsing discrepancies between Undertow and upstream proxies when handling crafted header names. The flaw (CWE-444) affects Undertow embedded in multiple Red Hat products including JBoss EAP 7/8, Data Grid 8, Fuse 7, and Apache Camel for Spring Boot 4, with Red Hat issuing patches via RHSA-2026:25125 and RHSA-2026:25126. There is no public exploit identified at time of analysis and EPSS is low (0.10%), but CVSS 9.1 and SSVC 'total' technical impact warrant prompt patching of internet-facing deployments.
Remote denial-of-service in libssh 0.11.x and earlier allows unauthenticated attackers to crash SSH server daemon processes via malformed GSSAPI authentication OID payloads. The vulnerability affects the ssh_get_hexa() API function when processing zero-length input, exploitable remotely when GSSAPI authentication is enabled and logging verbosity is set to SSH_LOG_PATCH (level 3) or higher. Red Hat, Ubuntu, SUSE, and Debian have released patches (libssh 0.11.4 and 0.12.0). EPSS score of 0.09% and SSVC assessment indicate low real-world exploitation likelihood despite network attack vector, with no active exploitation confirmed. Ubuntu classified this as low priority, and CISA SSVC notes exploitation as 'none' but 'automatable' with partial impact.
Denial of service in p11-kit's PKCS#11 RPC client allows a malicious remote token to trigger a NULL pointer dereference or undefined behavior in applications consuming derive-key operations. The flaw is reachable when an application calls C_DeriveKey against a remote token using IBM Kyber or IBM BTC derive mechanisms whose parameters are NULL, with the RPC client returning an uninitialized value. EPSS is low (0.10%) and no public exploit identified at time of analysis; SSVC marks exploitation as none but automatable.
Remote code execution is achievable in Red Hat Foreman and Satellite 6 via command injection in the WebSocket proxy implementation when users access VM VNC console functionality. An attacker controlling a malicious compute resource server can inject unsanitized hostname values into shell commands, compromising the Foreman server and potentially the entire managed infrastructure. A proof-of-concept exploit exists according to SSVC data, elevating real-world risk despite requiring low-privileged authentication and user interaction.
Heap buffer over-read in GIMP's PCX image loader allows a remote attacker who can convince a user to open a crafted PCX file to disclose adjacent heap memory and crash the application. The flaw stems from an off-by-one error (CWE-193) and is tracked across Red Hat Enterprise Linux 6 through 9. No public exploit identified at time of analysis and EPSS is very low (0.06%, 19th percentile), with CISA SSVC rating exploitation as 'none'.
A signed integer overflow vulnerability exists in the libtiff library's putcontig8bitYCbCr44tile function that leads to out-of-bounds heap writes through incorrect memory pointer calculations. Red Hat Enterprise Linux versions 6, 7, 8, 9, and 10 are confirmed affected. An attacker can exploit this by tricking a user into opening a specially crafted TIFF file, potentially achieving arbitrary code execution or causing application crashes.
The antchfx/xpath component in Debian is vulnerable to denial of service when processing specially crafted Boolean XPath expressions, which trigger an infinite loop in the logicalQuery.Select function consuming 100% CPU resources. Unauthenticated remote attackers can exploit this over the network without user interaction to disable affected systems. No patch is currently available.
The Feast Feature Server contains a path traversal vulnerability in its `/read-document` endpoint that allows unauthenticated remote attackers to read arbitrary files accessible to the server process, including sensitive system files, application configurations, and credentials. Red Hat OpenShift AI (RHOAI) deployments are confirmed affected across multiple versions. The vulnerability is rated 7.5 (High) with network-based exploitation requiring no authentication or user interaction, though no active exploitation (KEV) or public proof-of-concept is currently documented.
Heap memory disclosure in libarchive allows remote unauthenticated attackers to read sensitive heap data by submitting a malformed RAR archive. The flaw affects Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4, with vendor patches available per multiple RHSA advisories (RHSA-2026:8492 through RHSA-2026:8908). Despite the HIGH CVSS score of 7.5 and network-exploitable vector requiring no authentication, the EPSS score of 0.14% (35th percentile) indicates low observed exploitation probability. No public exploit code identified at time of analysis, and not listed in CISA KEV, suggesting this remains a patch-and-monitor priority rather than emergency response.
Keycloak contains an authentication bypass vulnerability in its SAML broker functionality that allows remote attackers with low-level privileges to complete IdP-initiated broker logins even when the SAML Identity Provider has been administratively disabled. Red Hat Build of Keycloak versions 26.2 and 26.4 are affected, with patches available in versions 26.2-16, 26.2.14-1, 26.4-12, and 26.4.10-1. The CVSS score of 8.1 reflects high confidentiality and integrity impact, though no evidence of active exploitation (KEV) or public proof-of-concept has been reported at this time.
Keycloak's SAML broker endpoint contains a validation flaw that allows attackers with a valid signed SAML assertion to inject encrypted assertions for arbitrary principals when the overall SAML response is unsigned. This leads to authentication bypass and unauthorized access to protected resources. Red Hat build of Keycloak versions 26.2 and 26.4 are affected, with patches available in versions 26.2-16, 26.2.14-1, 26.4-12, and 26.4.10-1. No evidence of active exploitation (not in CISA KEV) has been reported.
Information disclosure and denial-of-service in GNU Binutils' BFD linker (ld) arises from an out-of-bounds heap read when parsing malformed XCOFF object files. A local attacker who convinces a user to link or otherwise process a specially crafted XCOFF file can leak adjacent heap memory (CWE-125) or crash the linking process. Tracked by Red Hat across RHEL 6 through 10 and OpenShift 4; no public exploit is identified and EPSS exploitation probability is negligible (0.01%, 2nd percentile).
Out-of-bounds heap read in the BFD linker (ld) component of GNU Binutils allows information disclosure or an application-level crash when a victim is induced to process a crafted XCOFF object file. Affected across Red Hat Enterprise Linux 6 through 10 (and OpenShift Container Platform 4), exploitation requires user interaction and local file processing - there is no public exploit identified at time of analysis, and the EPSS probability is negligible (0.01%, 2nd percentile).
Infinite loop in libarchive's RAR5 decompression (archive_read_data) allows remote unauthenticated denial-of-service via malformed archive that passes checksum validation. Affects Red Hat Enterprise Linux 6-10 and OpenShift Container Platform 4. EPSS 0.04% (11th percentile) suggests low exploitation probability despite CVSS 7.5. Vendor patches available from Red Hat and Ubuntu. Upstream fix in libarchive PR#2877. No active exploitation confirmed (not in CISA KEV).
Keycloak's first broker login flow leaves a temporary account-linking proof behind after a federated identity link is established or manually removed (CWE-613), allowing an attacker who controls the external identity to silently re-establish the link and authenticate as the victim without any further confirmation. The flaw affects Red Hat Build of Keycloak and Red Hat Single Sign-On 7 deployments that use identity brokering, and carries high confidentiality and integrity impact despite a moderate CVSS base of 6.4. No public exploit code was identified at time of analysis and the issue is not listed in CISA KEV.
A path-handling flaw in the containers/storage Go library lets a crafted tar archive containing a malicious whiteout entry (for example 'victim/.wh.') cause UnpackLayer, ApplyLayer, or ApplyUncompressedLayer to replace the extraction destination directory with an arbitrary file. Systems that unpack container image layers with this library — notably Red Hat Enterprise Linux 10, Red Hat Ansible Automation Platform 2, OpenShift Container Platform 4, Quay 3, OpenShift Virtualization, Dev Spaces, and Red Hat Hardened Images — are in scope. Exploitation requires the operator or process to unpack an attacker-supplied archive, and the integrity impact is confined to the local extraction target; no public exploit code has been identified at time of analysis, and the vulnerability is not listed in CISA KEV, consistent with the modest CVSS 3.1 base score of 4.4.
GNOME Shell fails to validate the declared dimensions of icons returned by a remote search provider over D-Bus against the actual icon data buffer, producing an out-of-bounds read when an oversized size is supplied. A malicious or compromised search provider registered in a user's session can crash the shell — terminating the desktop session — and may leak fragments of adjacent shell memory. Rated CVSS 6.1 (AV:L/UI:R/C:L/A:H) by Red Hat; no public exploit code or CISA KEV entry was identified at time of analysis, so exploitation currently requires a locally present hostile search provider rather than remote access.
Confused deputy exploitation in hawtio-operator on OpenShift allows a namespace-scoped edit user to claim arbitrary externally-routable Route hostnames that would normally require elevated cluster permissions. The operator holds a cluster-wide `routes/custom-host:create` privilege and blindly propagates the tenant-controlled `spec.routeHostName` field from Hawtio custom resources into OpenShift Route specs without validating whether the requesting user is authorized to claim that hostname. The captured subdomain can then be combined with the cluster's auto-grant OAuthClient to hijack OAuth redirect flows and steal tokens from legitimate users (PR:L, UI:R, C:H, CVSS 6.3). No public exploit code has been identified at time of analysis.
Denial of service in multipathd allows a local attacker with access to the UNIX control socket to permanently block the daemon's listener thread by sending valid commands and then refusing to read the replies. This renders legitimate IPC operations - such as multipath path queries and storage management commands - unable to complete until the daemon is restarted. Red Hat, the reporting source, explicitly confirms the issue is bounded to availability impact only: no privilege escalation, no code execution, and no confidentiality or integrity loss. No public exploit code has been identified at time of analysis.
Heap buffer overflow in the libtiff `tiff2pdf` utility allows local attackers to cause severe memory corruption and application crashes by supplying a crafted BigTIFF file. The root cause is an integer truncation: a 64-bit `StripByteCounts` value is silently narrowed to 32 bits, producing an undersized heap allocation that a subsequent memory copy overflows. Red Hat has issued advisory RHSA-2026:53467 and an upstream fix is available via libtiff GitLab merge request #729; no public exploit or active exploitation has been identified at time of analysis.
Keycloak's Dynamic Client Registration endpoint exposes confidential client secrets in cleartext to users holding the view-clients realm management role, violating the principle of least privilege. Affected deployments include Red Hat Build of Keycloak and Red Hat Single Sign-On 7 across all tracked versions. An attacker granted only read-only view-clients access can harvest any confidential OAuth/OIDC client secret via the registration API and subsequently authenticate as that client, escalating their effective permissions within the realm to whatever the compromised client is authorized to do.
Symlink-following in libvirt's qemuTPMEmulatorPrepareHost() allows a local attacker with access to the swtpm service account to redirect a path-based chown() call - executed by libvirtd running as root - to transfer ownership of any arbitrary file on the system to the swtpm user. This affects libvirt on Red Hat Enterprise Linux 6 through 10. With ownership of a sensitive file such as /etc/shadow or a cron directory transferred to swtpm, the attacker gains a privilege escalation primitive beyond the swtpm account boundary. No public exploit or active exploitation has been identified at time of analysis.
Integer overflow in GStreamer's gst-plugins-good isomp4 plugin exposes adjacent heap memory when parsing CEA-608 closed-caption data embedded in specially crafted MP4 or MOV files. The 32-bit unsigned arithmetic wraparound bypasses a bounds check, enabling an out-of-bounds heap read of up to 244 bytes that is forwarded into downstream caption output - leaking process memory to an attacker who controls caption rendering output. Affected platforms include Red Hat Enterprise Linux 6 through 10; no public exploit has been identified at time of analysis, and no active exploitation is confirmed.
JavaScript injection in Evolution email client allows a remote, unauthenticated attacker to execute arbitrary JavaScript within the mail-viewing context by sending a specially crafted HTML email containing a spoofed vCard control. When the victim clicks the vCard control, Evolution's trusted JavaScript handler incorrectly places an attacker-controlled javascript: URL into an iframe's src attribute, bypassing Evolution's own script-execution protections for email content. The vulnerability is classified CWE-84 (improper neutralization of encoded URI schemes), and exploitation requires one user interaction gesture - clicking the vCard element - making it realistic against any Evolution user on a RHEL or GNOME desktop. No public exploit code or CISA KEV listing has been identified at time of analysis.
Pacemaker Configuration System (PCS) on Red Hat Enterprise Linux 8, 9, and 10 exposes an arbitrary file-read primitive to local members of the 'haclient' group via the `pcs host auth --token` command. The pcsd daemon reads the attacker-specified file path with root privileges, base64-encodes up to 256 bytes of content, and transmits it through cluster node communication channels the attacker controls - enabling exfiltration of short sensitive files such as API tokens, symmetric keys, or credential snippets that are otherwise inaccessible to the attacker. No public exploit has been identified at time of analysis, but the attack requires only local access and group membership, making it a realistic insider-privilege escalation threat in multi-tenant HA environments.
Symlink-following in crun's container runtime allows a low-privileged container user to redirect stdio file descriptors to host files and alter their ownership. Affecting crun 1.29.1 and earlier, the flaw manifests when crun reopens /dev/null for stdio after pivot_root: if the container's /dev/null has been replaced with a symlink to a host path, crun resolves the symlink outside the container namespace and chowns the target file to the container UID. No vendor-released patch is available at time of analysis. No public exploit identified at time of analysis.
Integrity escape in crun 1.29.1 and earlier allows a low-privileged local attacker to redirect /dev/console to an attacker-controlled filesystem path, breaking container boundary isolation. The flaw (CWE-59, improper link resolution) triggers during terminal setup when a container configuration omits a dedicated /dev mount, including via the read-only-rootfs bind-mount fallback path, resulting in a scope-changed integrity impact on the host. No vendor-released patch exists at time of analysis, and no public exploit has been identified.
Keycloak's Device Authorization Grant flow (RFC 8628) fails to enforce brute-force account lockout during token redemption, allowing an attacker holding an active device authorization session for a locked account to complete the flow and obtain valid access and refresh tokens. Affected deployments include Red Hat Build of Keycloak and Red Hat Single Sign-On 7 across all versions flagged in the CPE data. No public exploit code or CISA KEV listing has been identified at time of analysis, but the flaw silently undermines a core security control intended to stop credential-stuffing and persistent account compromise.
Uncontrolled recursion in Red Hat Service Interconnect 2's skupper-router AMQP field parser allows a remote unauthenticated attacker to crash the router by sending a specially crafted network message, resulting in denial of service for all services relying on the interconnected network. The vulnerability stems from an absent recursion depth limit during AMQP message parsing, causing stack memory exhaustion. No public exploit code has been identified at time of analysis, and the CVSS AC:H rating reflects the need to craft a payload that precisely triggers the unbounded recursion path.
Case-insensitive username comparisons in two code paths of the CUPS scheduler - printer ACL validation and private-attribute filtering - allow an authenticated adjacent-network attacker to bypass username-based access controls in configurations that rely on those ACLs. The bypass exposes private print attributes to users who should be excluded by ACL policy. Affected deployments span Red Hat Enterprise Linux 6 through 10, Red Hat Hardened Images, and OpenShift Container Platform 4. No public exploit or active exploitation has been identified at time of analysis, consistent with the low CVSS base score of 3.0.
Unconditional TLS certificate validation disabling in the OCAPI modules (ocapi_command, ocapi_info) of the community.general Ansible collection exposes HTTP Basic-Auth credentials to interception and permits response tampering against any managed OCAPI storage or enclosure device. Because the shared request helper disables certificate validation on every call with no parameter to re-enable it, a network-adjacent attacker performing a MITM attack can present any certificate, silently capture credentials, and inject falsified device responses back to the Ansible controller. Red Hat bundles the affected collection in Ceph Storage 5 and 9 and OpenStack Platform 17.1 and 18.0; no public exploit has been identified at time of analysis.
Heap out-of-bounds read in CUPS's cupsUTF32ToUTF8() transcoding function exposes partial daemon heap memory to adjacent-network attackers without authentication. The vulnerable code path is reachable via SNMP supply-description parsing, meaning any attacker who can spoof or inject crafted SNMP responses on the same network segment as a CUPS host can trigger the read and potentially leak heap contents from the printing daemon. No active exploitation has been identified, and the adjacent-network attack vector significantly limits the exposure surface.
Path traversal in the key provider component of Red Hat Build of Keycloak allows a realm administrator to probe arbitrary filesystem paths by supplying crafted keystore parameters, revealing the existence and readability of server-side files. The vulnerability exists because a prior fix for path probing was incomplete, leaving a residual bypass in the keycloak-services library - the core engine shared by both Red Hat Build of Keycloak and Red Hat Single Sign-On 7. No public exploit code has been identified at time of analysis, and exploitation requires realm administrator credentials, materially limiting opportunistic attack surface.
Symlink-following race condition in GLib2's g_file_replace() allows a local attacker with write access to the destination directory to redirect privileged file writes to arbitrary files. When the G_FILE_CREATE_REPLACE_DESTINATION flag is set and creation of the .goutputstream-XXXXXX temporary file fails, GLib2 unlinks the destination and then recreates it without O_EXCL (exclusive creation) or symlink-safe open semantics, opening a TOCTOU race window. An attacker who wins this race by placing a symlink at the destination path can cause any process using this code path - potentially running with elevated privileges - to overwrite files the attacker cannot directly modify. No public exploit has been identified at time of analysis.
Unauthenticated-read path exposure in the odh-dashboard component of Red Hat OpenShift AI allows any valid dashboard user to retrieve full Kubernetes Secret objects - including the cluster NVIDIA NGC API key (apiKeySecret) and NIM image pull secret (nimPullSecret) - via GET /api/nim-serving/:nimResource without an authorization check. The route uses the dashboard's elevated service account to proxy Kubernetes API calls, bypassing the admin-gating that protects the equivalent create and delete operations on the same NIM credentials. Affected organizations risk unauthorized access to NVIDIA NGC cloud services and private container registries under their accounts. No public exploit has been identified at time of analysis, and the vulnerability is not listed in CISA KEV.
Flatpak's `org.freedesktop.Flatpak.SystemHelper` D-Bus service contains a TOCTOU race condition in the `Deploy()` function where a privileged `chmod` executes before OSTree repository validation completes, allowing a local low-privileged attacker to redirect symlinks to arbitrary system files within that timing window. A successful exploit can yield high-confidentiality impact (reading privileged files) and limited integrity and availability impact (CVSS C:H/I:L/A:L), as the unguarded chmod can be inherited by attacker-controlled symlink targets. No public exploit code or CISA KEV listing has been identified at time of analysis, and the High attack complexity (AC:H) reflects the precision timing required to win the race.
Heap out-of-bounds read in libtpms during TPM 2.0 state restoration allows an adjacent unauthenticated attacker to crash the swtpm process and deny TPM services to dependent virtual machines. The flaw arises in the state-blob parser: an attacker-controlled oversized skip-block length drives the internal INT32 size counter negative; subsequent bounds checks cast that counter to UINT32, wrapping it to a large positive value and bypassing the check, which then drives the parser to read memory outside the heap buffer. Vendor and upstream commit confirm the impact is denial of service only - no data corruption or information disclosure was confirmed. No public exploit or CISA KEV listing has been identified.
HTTP/2 flow-control window mismanagement in libsoup (GNOME's HTTP client/server library) allows a malicious HTTP/2 server to abort a connecting client process or crash its HTTP/2 session. When the client sends a request body sourced from a non-pollable GInputStream, libsoup buffers the data before transmission; a server that then shrinks SETTINGS_INITIAL_WINDOW_SIZE causes the client to copy the full pre-buffered payload into a now-undersized DATA callback without a runtime bounds check, triggering a reachable assertion abort (CWE-617). No public exploit has been identified at time of analysis, and the high-complexity timing requirement constrains practical exploitation.
Integer overflow in Corosync's membership commit token processing crashes the daemon on 32-bit cluster nodes, enabling a denial-of-service attack from any adjacent network host. The CWE-190 flaw causes the length validation to be bypassed on 32-bit systems where arithmetic wraps before the bounds check is applied, resulting in an out-of-bounds memory access that kills the Corosync process. Modern 64-bit deployments of the same packages are explicitly not affected, substantially narrowing real-world exposure despite the CVSS 6.5 rating; no public exploit code or CISA KEV listing exists at time of analysis.
Key-ID (kid) bypass in the jwcrypto Python JOSE library allows an attacker who holds any valid key within a JWK set to forge a General JSON Serialization JWS that satisfies verification for a different kid, effectively impersonating another tenant, user, or service. Affected deployments include Red Hat Ansible Automation Platform 2, RHEL 7-10, Red Hat OpenShift AI (RHOAI), and Red Hat OpenStack Platform 16.2, wherever jwcrypto performs JWS signature verification with kid-based authorization. No public exploit or CISA KEV listing has been identified at time of analysis, and the EPSS score is not provided, but the integrity impact is high for multi-tenant architectures.
Stack exhaustion in gfs2-utils's metawalk.c metadata walk code allows a local attacker to cause denial of service by supplying a crafted GFS2 filesystem image containing a maliciously large inode height value that drives unbounded alloca() calls. Affected systems include Red Hat Enterprise Linux 7, 8, and 9 with gfs2-utils installed; the CVSS 4.7 medium rating reflects a local, high-complexity, user-interaction-required attack path with no confidentiality or integrity impact. No public exploit code or active exploitation has been identified at time of analysis.
Heap out-of-bounds read in gfs2-utils enables memory disclosure and potential crashes when parsing crafted GFS2 filesystem images. The `ea_num_ptrs` field embedded in on-disk extended attribute metadata is consumed without validating it against the available buffer boundary, allowing an attacker who controls a filesystem image to trigger a heap over-read. Affected across Red Hat Enterprise Linux 7, 8, and 9; no public exploit is identified at time of analysis, and the local, user-interaction-dependent attack vector substantially limits practical exploitation.
Stack exhaustion in gfs2-utils allows an attacker who can deliver a crafted GFS2 filesystem image to crash fsck.gfs2, gfs2_edit, or savemeta on Red Hat Enterprise Linux 7, 8, and 9. The root cause is unbounded use of alloca() in metawalk.c's hash table traversal, where the allocation size is derived exponentially from the on-disk di_depth field with no upper-bound check, so a sufficiently large di_depth value causes the process stack to be fully consumed. The impact is limited to denial of service of the affected utility; no public exploit has been identified at time of analysis, and EPSS data is not available in the provided intelligence.
Crash of the gvfsd-mtp daemon in gvfs is achievable by anyone who can connect a malicious USB MTP device to a target Linux system. The do_read() function in gvfsbackendmtp.c accepts the byte-count reported by the device at face value and passes it uncapped to memcpy(), causing an out-of-bounds read that triggers a segmentation fault when the device deliberately over-reports its response length. The vulnerability affects gvfs as packaged across Red Hat Enterprise Linux 6 through 10; no public exploit has been identified and exploitation is constrained by physical proximity.
Heap buffer overflow in the gvfs AFP (Apple Filing Protocol) backend allows a malicious AFP server to crash the gvfsd-afp process on connecting clients, resulting in denial of service. When a client mounts an AFP share, the DSI (Data Stream Interface) read path accepts a server-supplied length value without validating it against the pre-allocated reply buffer, enabling the server to write past buffer boundaries. This affects RHEL 6 through 10 and requires user interaction to mount a malicious share; no public exploit or CISA KEV listing has been identified at time of analysis.
Uninitialized heap memory disclosure in gvfs's SFTP backend enables a malicious SFTP server to deterministically defeat ASLR on client systems running RHEL 6 through 10. When a user mounts a crafted SFTP share, the read_string() parser allocates a buffer for the FXP_HANDLE response but does not verify that the buffer is fully populated; the client subsequently echoes the uninitialized remainder - containing heap base pointers and the libgio load address - back to the attacker on every subsequent file-handle request. No public exploit has been identified at time of analysis, and the issue does not appear in CISA KEV, but the ASLR bypass it achieves is a high-value precursor for chained memory-corruption attacks against gvfsd-sftp.
Stored cross-site scripting in pulpcore's content serving layer allows authenticated users with file upload permissions to execute arbitrary JavaScript in the browsers of other users. When pulpcore uses local filesystem storage, uploaded files are served with their original MIME types (e.g., text/html, image/svg+xml) and without a Content-Disposition: attachment header, causing browsers to render the files inline within the host application's origin instead of prompting a download. This flaw affects Red Hat Ansible Automation Platform 2, Red Hat Satellite 6, and Red Hat Update Infrastructure 4 and 5; no public exploit code or confirmed active exploitation is identified at time of analysis.
Unauthenticated enumeration of internal PKI topology is possible in Red Hat Certificate System 9 through an unprotected REST endpoint. Any network-accessible client can issue GET /ca/rest/securityDomain/hosts and receive a structured inventory of all participating CA subsystem hosts, their roles, and security domain membership - without presenting credentials, a client certificate, or a session token. While the direct CVSS impact is rated medium (5.3), the real-world significance lies in enabling precise reconnaissance of internal PKI infrastructure that could facilitate targeted follow-on attacks against specific subsystems. No active exploitation is confirmed and no public exploit code has been identified at time of analysis.
Unauthenticated network attackers can elicit Java stack traces from Red Hat IdM's Dogtag CA REST enrollment endpoint (POST /ca/rest/certrequests) by submitting malformed requests, causing HTTP 500 responses that expose internal implementation details under CWE-209. The same error path simultaneously amplifies the CA debug log with large multi-line stack traces, creating a log-fill resource exhaustion vector that drives disk growth and I/O contention on affected RHEL 6 through 10 deployments. No public exploit has been identified at time of analysis, but the attack requires no authentication and low complexity, making it accessible to unskilled opportunistic attackers targeting IdM infrastructure.
Heap metadata corruption in the popt command-line parsing library's `poptConfigFileToString` function can be triggered by a local, low-privileged attacker who supplies specially crafted configuration file content to an affected host. Successful exploitation causes the consuming process to crash, resulting in denial of service. CVSS 2.5 (Low) reflects the strictly local, high-complexity exploitation path with no confidentiality or integrity impact; no public exploit code or active exploitation (CISA KEV) is known at time of analysis.
Heap out-of-bounds read and stack out-of-bounds access in GIMP's file-psd plugin allow an attacker to crash the application or disclose limited memory contents by convincing a user to open a specially crafted PSD image. The flaw affects GIMP as shipped in Red Hat Enterprise Linux 6 through 9 and stems from missing validation of the channel-count parameter during PSD parsing. No active exploitation has been identified; the attack requires local file delivery and deliberate user interaction, significantly constraining real-world risk.
Heap out-of-bounds read in GIMP's file-pvr plugin exposes users of Red Hat Enterprise Linux 6 through 9 to application crashes and limited heap memory disclosure when opening a crafted PVR image file. The VQ (Vector Quantization) compressed-texture decoder omits mandatory bounds validation, allowing a malicious image to read beyond allocated heap regions. Impact is primarily denial of service via crash, with a secondary low-severity information disclosure path; no public exploit code and no CISA KEV listing are associated with this issue at time of analysis.
Heap out-of-bounds read in GIMP's file-ico plugin allows a local attacker to crash GIMP or leak limited heap memory contents by delivering a specially crafted ICO image file to a victim user. Affected packages span Red Hat Enterprise Linux 6 through 9. No public exploit code or CISA KEV listing exists at time of analysis, but the user-interaction requirement (opening a malicious file) is the primary delivery mechanism and a realistic social-engineering target in image-processing workflows.
Out-of-bounds memory write in libsolv crashes RPM-based package manager tools (dnf, yum, zypper) when processing a corrupted or specially crafted .solv repository cache file. The root cause is an absent array-index bounds check on directory-id values read from compressed filelist data during .solv file rewriting - but because the out-of-bounds write stores only a fixed, non-attacker-controlled value, the vendor explicitly rules out arbitrary code execution, confining impact to denial of service. No public exploit has been identified and no active exploitation is confirmed; note that the 'RCE' metadata tag conflicts directly with the description and appears to be erroneous.
Heap out-of-bounds read in GIMP's file-iff plugin allows a local attacker to crash the application or disclose limited heap memory contents by delivering a specially crafted IFF/ILBM image file. The flaw stems from missing validation of HAM row size when the number of color planes (nPlanes) is zero, causing a size mismatch that bypasses memory bounds checking. No active exploitation has been confirmed (not in CISA KEV) and no public exploit code has been identified at time of analysis.
Heap buffer overflow in FFmpeg's TDSC screen-capture codec decoder exposes Red Hat Enterprise Linux AI 3 and OpenShift AI deployments to denial of service or potential arbitrary code execution. The tdsc_load_cursor() function performs erroneous stride-based pointer arithmetic in two locations when rendering cursor data from crafted TDSC video, writing past a heap-allocated buffer boundary. No public exploit or active exploitation has been confirmed at time of analysis, and the upstream fix is available as FFmpeg commit 242ff799c.
Denial of service in jwcrypto's JWE.deserialize() function allows a remote unauthenticated attacker to crash any service that processes untrusted JWE tokens by submitting a malformed compact serialization containing an excessive number of period delimiters, triggering uncontrolled memory allocation and a MemoryError. Affected deployments include Red Hat Ansible Automation Platform 2, RHEL 9 and 10, OpenShift AI (RHOAI), and OpenStack Platform 16.2 as disclosed via Red Hat Bugzilla 2524147 and upstream advisory GHSA-96rv-c4vc-h4f4. No public exploit code or CISA KEV listing exists at time of analysis, and impact is confined to availability with no confidentiality or integrity exposure.
Out-of-bounds write in gdk-pixbuf's JPEG decoder affects any application on Red Hat Enterprise Linux 6 through 10 that renders JPEG images containing chunked ICC profile markers. When ICC profile parsing encounters an error, stale size metadata persists after the profile buffer is freed; a subsequent allocation within the same decode operation then writes beyond buffer boundaries, crashing the application. No active exploitation has been identified (no CISA KEV listing), and no public exploit code is known at time of analysis, but the availability-only impact and user-interaction requirement make this a realistic denial-of-service risk in desktop and server image-processing contexts.
Cross-organization IDOR in Katello's Content View Filter Rules API allows authenticated low-privileged users to access and modify filter rules belonging to Content View Filters in other organizations by supplying a foreign filter identifier. Red Hat Satellite 6 deployments running multi-organization configurations are affected, as the API enforces authorization on the Content View but fails to validate the parent Content View Filter's organizational boundary. No public exploit code or active exploitation has been identified at time of analysis, and the CVSS score of 5.4 (Medium) reflects the limited scope - authenticated access and Satellite's enterprise context constrain real-world exposure.
Foreman's template revision endpoint, as shipped in Red Hat Satellite 6, exposes historical template contents across organizational and location boundaries due to missing object-level authorization (IDOR/BOLA, CWE-639). An authenticated user holding any template-related permission - as minimal as view_ptables - can retrieve audit-history revisions owned by other organizations simply by supplying a guessable audit ID. Template revisions may contain credentials, secrets, or sensitive configuration data, making the confidentiality impact high despite the low attack complexity. No public exploit has been identified at time of analysis, though the low-privilege entry bar lowers the practical exploitation threshold significantly.
Stack-based denial of service in GIMP's Seattle FilmWorks (SFW) image plugin crashes the application when a crafted SFW file triggers an unbounded variable-length array allocation on the stack. The flaw affects all GIMP versions per the GNOME CPE string and is confirmed across Red Hat Enterprise Linux 6 through 9. An attacker who can deliver a malicious SFW file to a user can reliably crash the GIMP process with no code execution or data exposure; no public exploit has been identified at time of analysis.
Cross-organizational information disclosure in Katello - the content management engine of Red Hat Satellite 6 - allows any authenticated user to read lifecycle history of Content Views belonging to organizations other than their own. By supplying an arbitrary Content View identifier to the Content View History API endpoint, a low-privileged user bypasses organization-scope authorization and retrieves publication events, promotion history, associated usernames, and timestamps for foreign tenants. No public exploit has been identified at time of analysis, and no CISA KEV listing exists; the CVSS 4.3 Medium rating reflects the strictly read-only, single-organization-boundary impact.
Heap out-of-bounds read in GIMP's file-xwd plugin allows a crafted XWD image file to trigger an application crash or leak partial heap memory contents into the rendered image output. Users running GIMP on Red Hat Enterprise Linux 6 through 9 are affected when they open a malicious XWD file; the plugin fails to cross-validate image width and bytes-per-line parameters against the allocated buffer size, permitting an out-of-bounds read. No public exploit is identified at time of analysis and the vulnerability is not listed in CISA KEV, placing real-world urgency in the low-to-moderate range.
CPU exhaustion in libsoup's HTTP Range header processing affects any SoupServer deployment carrying the CVE-2025-32907 fix but not MR !550. Supplying a Range header with approximately 25,000 repeated satisfiable byte ranges triggers an O(N²) coalescing loop - each g_array_remove_index() call induces an O(N) memmove on GArray - blocking the server's event loop for roughly 90 ms per request from a single unauthenticated client. The description explicitly rules out memory corruption and information disclosure; this is a pure availability issue with no public exploit identified at time of analysis.
Server-side request forgery in galaxy_ng, the Ansible Galaxy server plugin for Pulp, allows authenticated users holding namespace management permissions to redirect a background worker process into probing arbitrary internal network addresses, including loopback interfaces and cloud instance metadata endpoints (e.g., 169.254.169.254). The dual-impact vulnerability enables both internal network reconnaissance (enumerating reachable IPs and reading service responses) and a denial-of-service condition against background workers due to the absence of an HTTP client timeout. No public exploit has been identified at time of analysis, and no confirmed KEV listing exists; however, the scope-changing CVSS vector (S:C) reflects that impact crosses trust boundaries from the application into adjacent internal infrastructure.
Resource exhaustion via crafted SASL UNBIND in 389 Directory Server (389-ds-base) allows a remote authenticated attacker to stall connections and deny LDAP service to legitimate users. Affected deployments span Red Hat Directory Server 11, 12, and 13, plus 389-ds-base as packaged across RHEL 6 through 10. No public exploit code or CISA KEV listing has been identified at time of analysis, though the CVSS 6.5 rating (AV:N/AC:L/PR:L) indicates low-complexity network exploitation requiring only a low-privilege LDAP bind - a realistic bar in any environment with shared directory users.
Stack buffer overflow in file-roller's archive extraction path causes denial of service when a victim opens or extracts a crafted 7z or RAR archive containing an excessively long file path entry. The unbounded string copy in the progress-line parsing routine overwrites a fixed-size stack buffer, crashing the application with no confidentiality or integrity impact. No public exploit code or CISA KEV listing has been identified at time of analysis, and exploitation is gated entirely on user interaction with a malicious archive.
CRI-O's container-creation code path crashes the daemon with an unrecovered Go runtime panic when processing an OCI image whose config.Env contains a malformed entry lacking an '=' character, under the specific condition that the CreateContainer request supplies a nil CRI Envs field. The crash terminates the crio daemon process, disrupting all container workloads on the affected node until the service is manually restarted - a node-wide denial of service. Affecting Red Hat OpenShift Container Platform 4, this requires high privileges (PR:H) to exploit; no public exploit code or CISA KEV listing has been identified at time of analysis.
Stack exhaustion and a bounded memory over-read in GIMP's file-pix (ESM) plugin allow a crafted PIX image to crash the application and leak 21 bytes of stack memory into an intermediate file. Users running GIMP on Red Hat Enterprise Linux 6 through 9 are affected when opening untrusted PIX format images. No public exploit code and no active exploitation (CISA KEV) have been identified at time of analysis, though the DoS impact is reliable and the delivery vector - a malicious image file - is realistic for desktop users.
Improper certificate validation in JSS (Java Security Services) allows the JSSTrustManager class to accept CA certificates from the NSS database that lack TRUSTED_CA trust flags, meaning certificates never explicitly designated as trust anchors can still be used to anchor TLS chains. In non-default deployments where certificate revocation checking has been disabled, this creates a viable path for a man-in-the-middle attacker to forge certificates accepted by PKI client connections, with high confidentiality and low integrity impact. No public exploit has been identified at time of analysis, and the AC:H CVSS rating reflects the meaningful attack complexity - MITM positioning plus a specific non-default configuration must both be present.
Improper access control in Lighthouse - the cross-cluster service-discovery component of Submariner shipped with Red Hat Advanced Cluster Management for Kubernetes 2 - lets an attacker who has compromised a spoke cluster inject unauthorized EndpointSlices and ServiceImports into arbitrary namespaces on peer clusters. Because the destination namespace is taken from an attacker-controlled label/annotation on the broker object, resources can be planted into privileged namespaces such as kube-system and openshift-*, enabling privilege escalation and lateral cluster compromise. Rated CVSS 9.9 with a scope change; no public exploit identified at time of analysis.
Cross-cluster MITM attacks are enabled in Red Hat Advanced Cluster Management for Kubernetes 2.x via the lighthouse service discovery component, which fails to validate IP addresses advertised in EndpointSlice objects. An attacker controlling a compromised spoke cluster can inject arbitrary IP addresses into EndpointSlices, causing lighthouse DNS resolution across all connected clusters to redirect legitimate cross-cluster service traffic to attacker-controlled endpoints. The CVSS Scope:Changed metric confirms that impact propagates beyond the compromised spoke cluster to the hub and peer clusters, enabling unauthorized interception and manipulation of inter-cluster communications. No public exploit code or CISA KEV listing has been identified at time of analysis.
Cross-cluster traffic redirection in Submariner (as shipped with Red Hat Advanced Cluster Management for Kubernetes 2) allows a malicious or compromised member cluster to hijack traffic from peer clusters by advertising a specially crafted network endpoint. Because Submariner does not validate the subnets a spoke cluster declares, an attacker-controlled cluster can claim arbitrary CIDR ranges and cause peer clusters to route all matching traffic through the attacker's tunnel, enabling information disclosure and denial of connectivity. Rated CVSS 9.9 with a changed scope, this affects the multicluster networking layer, though there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in FreeIPA's ipa-enrollment SLAPI plugin allows any authenticated LDAP client to crash the 389 Directory Server by sending a malformed extended operation. The flaw (CWE-476, null pointer dereference) is triggered by omitting the request value for the JOIN_OID in the ipa-enrollment extended operation, causing the server to dereference a null pointer and crash. No public exploit or active exploitation has been identified at time of analysis; however, the low attack complexity and network-accessible vector make this a credible threat against any RHEL Identity Management deployment.
Resource exhaustion in FreeIPA's OTP key processing path allows any low-privilege authenticated domain user to degrade the IPA authentication service. By submitting an oversized One-Time Password key, the user triggers an unbounded decode/re-encode cycle (CWE-770) that consumes excessive CPU and memory, degrading availability for all dependent systems and users. No public exploit code exists at time of analysis, and this CVE is not listed in CISA KEV; however, the AV:N/PR:L CVSS vector means any valid domain account on a network-accessible FreeIPA instance is sufficient to trigger the condition.
Integer truncation in libsoup's SoupServer Range-header comparator silently drops byte ranges from HTTP 206 Partial Content responses when the target resource exceeds approximately 2 GB. The sort_ranges() function in soup-message-headers.c narrows a 64-bit offset subtraction to a 32-bit int return value, inverting the comparator sign whenever offsets differ by more than INT_MAX, causing incorrect range sorting and silent omission of content. No public exploit code or CISA KEV listing has been identified at time of analysis; exploitation requires network access to a SoupServer instance serving files larger than ~2 GB.
Cross-cluster data integrity violation in Red Hat Advanced Cluster Management for Kubernetes 2 allows a registered and authenticated managed cluster to tamper with or delete indexed search data belonging to other clusters. The flaw resides in the delta-sync write paths of the search-indexer component, which fails to enforce cluster-scoped ownership checks before processing UPDATE and DELETE operations. With no public exploit identified at time of analysis and no CISA KEV listing, the practical risk is bounded by the requirement for an already-registered cluster credential, though the Changed scope (S:C) elevates concern in multi-tenant fleet environments where cluster isolation is an assumed security boundary.
The AdvertiseListenerImpl component in mod_cluster's core multicast UDP handler can be permanently crashed by a single crafted datagram, affecting Red Hat JBoss Enterprise Application Platform 7 and 8, JBoss Web Server 5 through 7, and Red Hat Single Sign-On 7. An unauthenticated attacker with adjacency to the mod_cluster multicast group can silently terminate the advertise listener thread, causing the affected node to stop receiving cluster topology updates until manually restarted - with no runtime indication of failure since isListening() continues returning true. No public exploit is identified at time of analysis, and this CVE is not listed in the CISA KEV catalog based on available data.
Heap overread in swtpm's SWTPM_NVRAM_CheckHeader() function allows local low-privileged users to crash the swtpm daemon and leak heap memory contents to system logs on Red Hat Enterprise Linux 8, 9, and 10. The root cause is a classic sizeof-pointer vs. sizeof-struct confusion: the guard compares buffer length against sizeof(bh) (pointer width, 8 bytes on 64-bit) rather than sizeof(*bh) (actual struct size), permitting undersized buffers to bypass validation and triggering a 2-byte heap overread on 64-bit systems or 6 bytes on 32-bit. No public exploit or CISA KEV listing has been identified at time of analysis.
Cross-cluster traffic interception in Submariner (shipped within Red Hat Advanced Cluster Management for Kubernetes 2) allows a single compromised member cluster to overwrite the endpoint records of other clusters in the mesh. Because the submariner-k8s-broker-cluster Role granted to every joined cluster carries more write access than it needs, an attacker holding one cluster's broker credentials can reroute inter-cluster tunnel traffic through attacker-controlled endpoints and mount a mesh-wide man-in-the-middle. Rated CVSS 9.9 with a scope change; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Remote code execution in the submariner-operator component of Red Hat Advanced Cluster Management for Kubernetes 2.x allows a cluster administrator-or any user holding RBAC permissions to modify the Submariner Custom Resource-to reference an unvalidated, attacker-controlled container image path, causing the operator to deploy and execute arbitrary code with elevated privileges across the entire cluster, including control-plane nodes. The root cause (CWE-20: Improper Input Validation) is the absence of image path sanitization or verification before the operator acts on the Submariner CR field, enabling privilege escalation beyond the user's intended cluster boundary. No public exploit code and no CISA KEV listing have been identified at time of analysis, but the Changed Scope with full C:H/I:H/A:H impact ratings signal potential for complete cluster compromise once the high-privilege prerequisite is met.
