Deploy-time policy bypass in Red Hat Advanced Cluster Security for Kubernetes 4 lets a user with Kubernetes Deployment-create permission spoof workload identity by setting the openshift.io/encoded-deployment-config label to "null", forcing ACS to record the workload with empty UID, name and labels and a "default" namespace. This evades ACS deploy-time policy detection and enforcement visibility and corrupts Central's persistence, violation reporting and compliance correlation. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Token exchange in Keycloak bypasses Google Workspace domain allowlist restrictions, enabling any valid Google account holder - regardless of their domain - to swap a Google OAuth token for a Keycloak realm token and gain unauthorized access. Affected deployments are those specifically configured to restrict Google-based logins to approved Workspace domains while also having token exchange enabled; both conditions must be present. No public exploit code has been identified at time of analysis, and EPSS sits at 0.20% (10th percentile), consistent with SSVC's exploitation status of 'none', though SSVC rates technical impact as 'total' given that successful exploitation delivers full realm access.
Tenant-restriction bypass in Keycloak's Microsoft identity provider integration allows attackers holding any valid Microsoft OAuth token - even from a completely unrelated Azure AD organization - to authenticate into a Keycloak realm via the token exchange feature. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and Red Hat JBoss EAP Expansion Pack. With CVSS PR:L reflecting the need for a valid Microsoft credential (trivially obtained by registering a free Azure tenant), successful exploitation grants high confidentiality and integrity impact within the realm. No public exploit or active exploitation has been identified at time of analysis; EPSS sits at 0.19% (9th percentile), consistent with SSVC exploitation=none.
Local privilege escalation to root via argument injection in the APT backend of yggdrasil-worker-package-manager, the Red Hat Insights remote package-management worker shipped with Red Hat Enterprise Linux 10. Because package names are passed directly to apt-get without an argument terminator, a name beginning with a hyphen is parsed as a command-line option rather than a package, letting an attacker who can influence the package list achieve root-level remote code execution. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but an upstream source fix is already merged and released in versions 0.1.4 and 0.2.4.
Confidential Active Directory attribute disclosure in Samba's Active Directory Domain Controller allows an authenticated low-privilege domain user to read protected directory attributes by abusing how LDAP Compare requests are handled. Because Samba fails to validate user-supplied attribute names (LDAP filter injection, CWE-90) and runs the resulting internal search in a trusted context, normal ACL enforcement is bypassed; in gMSA-enabled deployments this permits extraction of msKds-RootKeyData and offline derivation of Group Managed Service Account passwords, which can escalate to full domain compromise. No public exploit identified at time of analysis and the issue is not listed in CISA KEV, but a vendor patch is available.
Remote unauthenticated denial of service in Performance Co-Pilot (PCP), the system performance monitoring toolkit shipped with Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4, allows an attacker to permanently disable a PCP daemon by triggering a signed integer overflow (CWE-190) in the __pmGetPDU() PDU-length handling routine. A crafted network packet sent during normal PDU processing or SASL authentication negotiation corrupts the read logic so that the daemon can no longer read any subsequent packets, requiring a manual restart. There is no public exploit identified at time of analysis and the flaw yields no code execution or data exposure - impact is availability-only (CVSS 7.5, A:H).
Remote unauthenticated access-control bypass in the Performance Co-Pilot (PCP) pmproxy component lets attackers reach the /store endpoint and overwrite arbitrary PMDA (Performance Metrics Domain Agent) metric values, which the reporter (Red Hat) states can escalate to arbitrary code execution and full system takeover. The flaw affects PCP as shipped across Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the network-reachable, no-authentication attack surface makes exposed pmproxy instances a meaningful risk.
Local privilege escalation in Performance Co-Pilot (PCP) on Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4 arises from the linux_sockets module exposing an unsecured internal connection. An attacker who already holds low-level code execution on the host can leverage this leaked/unprotected socket to run arbitrary commands as root. No public exploit has been identified at time of analysis and the flaw is not in CISA KEV, so exploitation would require an existing foothold rather than remote unauthenticated access.
Local privilege-relevant command injection in Performance Co-Pilot's (PCP) linux_sockets PMDA lets an authenticated user inject shell metacharacters through the network.persocket.filter metric, causing arbitrary commands to run as the PMDA user each time metrics refresh. Reported by Red Hat, it affects the pcp packages shipped across Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Robot account token disclosure in Red Hat Quay 3 allows a user assigned to the GLOBAL_READONLY_SUPER_USERS role to read the tokens of robot accounts belonging to repositories they are not a member of. Because these tokens are long-lived registry credentials, the read-only superuser can escalate a view-only role into full impersonation of any robot account, gaining whatever push/pull and repository permissions that robot holds. No public exploit identified at time of analysis; not listed in CISA KEV.
Out-of-bounds write in GNU binutils' BFD library (bfd/elf32-dlx.c) lets a crafted ELF/DLX object file corrupt memory and achieve arbitrary code execution when parsed by any BFD-consuming tool (objdump, readelf, strip, ld, nm, objcopy). Reported by Red Hat and tracked against RHEL 6-10, Hardened Images and OpenShift 4, the flaw is only reachable when binutils is compiled with the DLX backend (typically --enable-targets=all), so exposure is gated by a non-default build option. There is no public exploit identified at time of analysis (not in CISA KEV), though the researcher demonstrated code execution via a File Stream Oriented Programming (FSOP) attack on glibc FILE structures.
Privilege escalation in CRIU allows a malicious container process to spoof credentials during checkpoint, resulting in elevated capabilities upon restore. On Red Hat platforms, effective exploitation is mitigated by mandatory access controls, user namespaces, and the requirement for privileged checkpoint initiation. No public exploit identified at time of analysis.
Arbitrary command execution as root via udev property injection in sg3_utils when sg_inq --export parses a SCSI device with a crafted name string. Affects multiple Red Hat Enterprise Linux versions shipping sg3_utils. Publicly available exploit code exists as a proof-of-concept in the upstream fix; no active exploitation has been reported.
Identity header smuggling in OpenShift Container Platform 4.x allows authenticated low-privilege users to escalate privileges by injecting forged identity headers that upstream applications may trust. The oauth-proxy fails to strip underscore-variant headers, enabling WSGI and PHP frameworks to normalize them into the legitimate identity, potentially overriding the true authenticated user. No known active exploitation or public exploit code has been identified.
Header injection in the cluster-proxy service-proxy component of Red Hat Advanced Cluster Management for Kubernetes (RHACM) and multicluster-engine (MCE) allows an authenticated hub principal to escalate to cluster-admin across all managed spoke clusters. The service-proxy forwards Kubernetes impersonation group headers to spoke clusters without stripping caller-supplied values first; because the spoke ServiceAccount holds unrestricted impersonation rights, an injected Impersonate-Group header (e.g., system:masters) is honored by every downstream cluster API server. No public exploit has been identified at time of analysis, and EPSS sits at 0.23%, though SSVC rates technical impact as total given the blast radius across the entire managed fleet.
Denial of service in OpenPrinting libcupsfilters (as shipped in Red Hat Enterprise Linux 7 through 10) allows a network-adjacent attacker to pin a CPU at 100% by broadcasting a crafted printer advertisement. The flaw lies in cfIEEE1284NormalizeMakeModel(), which enters an infinite loop (CWE-835) when parsing an IEEE-1284 device ID whose model field is empty. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; impact is limited to availability with no data compromise.
Authentication bypass in the odh-dashboard web console of Red Hat OpenShift AI (RHOAI) lets a low-privileged actor already inside the cluster impersonate any user — including cluster administrators — by supplying an arbitrary access token to a component that was incorrectly bound to a reachable network interface. Because the impersonated identity is honored against the Kubernetes API, this escalates to arbitrary code execution, privilege escalation, and information disclosure across the cluster. There is no public exploit identified at time of analysis, no CISA KEV listing, and no EPSS score was provided, but the CVSS 8.8 (High) rating and full C/I/A impact make it a serious internal-threat priority.
Local code execution in the Visual Studio Code Ansible (Lightspeed) extension lets a malicious project run arbitrary shell commands on a developer's machine by abusing the ansible.executionEnvironment.containerOptions and volumeMounts settings, which fail to sanitize shell separators (CWE-78). Because these are workspace-scoped settings, simply opening a booby-trapped repository can auto-trigger execution during Language Server initialization, yielding code execution as the VS Code user. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; CVSS is 7.8 (High).
Arbitrary command execution in ansible-core allows an attacker who controls a collection source URI to run commands on a victim's machine when that victim executes 'ansible-galaxy collection install' against the malicious git source. The flaw lives in _extract_collection_from_git() in concrete_artifact_manager.py, which builds git clone commands without a '--' end-of-options separator, letting crafted URIs be parsed as git arguments. It is an incomplete fix for CVE-2026-11332, which patched the analogous role-install path but left the collection-install path exposed; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Privilege escalation via authentication bypass in libssh affects servers that enable GSSAPIKeyExchange, where the gssapi-keyex authentication path fails to confirm that the authenticated Kerberos principal is actually authorized for the local user account being requested. An already-authenticated client holding any valid Kerberos principal in the realm can therefore log in as an arbitrary user, including potentially privileged accounts, on Red Hat Enterprise Linux 8, 9, and 10 and Red Hat Hardened Images. No public exploit is identified at time of analysis and the issue is not listed in CISA KEV, but the CVSS of 8.8 reflects a straightforward, low-complexity abuse once a valid Kerberos credential is held.
Denial of service (and potential use-after-free) in libssh occurs when the library processes SSH data packets that arrive after a channel has been closed, causing channel data callbacks to fire against already-freed memory. Any application or system linking the affected libssh - including Red Hat Enterprise Linux 8, 9, and 10 and Red Hat Hardened Images - can be crashed by a malicious SSH peer that sends channel data at the wrong point in the connection lifecycle. There is no public exploit identified at time of analysis, EPSS is low (0.26%), and CISA SSVC scores exploitation as none, indicating a real but non-urgent memory-safety fix.
Denial of service in libssh affects clients that use automatic certificate-based public key authentication, where logic errors cause the client to loop indefinitely when configured certificates are absent or are repeatedly rejected by the SSH server. Reported by Red Hat and shipped in Red Hat Enterprise Linux 8, 9, and 10 plus Red Hat Hardened Images, the flaw lets a hostile or misconfigured server hang a connecting client and consume CPU. There is no public exploit identified at time of analysis, and EPSS is low at 0.17% (7th percentile), consistent with an availability-only, client-side bug rather than a mass-exploited issue.
Integrity-protection bypass in libssh builds compiled against the OpenSSL crypto backend, caused by incorrect AES-GCM finalization checks that fail to verify the authentication tag. An in-path (man-in-the-middle) attacker positioned on an SSH session can silently alter plaintext bytes on the wire without triggering a MAC/integrity failure, defeating a core guarantee of the SSH transport layer. There is no public exploit identified at time of analysis, EPSS risk is low (0.28%, 20th percentile), and CISA SSVC rates exploitation as 'none' though 'automatable: yes'.
Denial of service in libcupsfilters and cups-filters (the OpenPrinting image-filtering stack bundled with Red Hat Enterprise Linux 7 through 10) allows an unauthenticated attacker to abort the CUPS image filter by submitting a specially crafted PNG print job. The PNG reader instantiates a libpng decoder without registering an error-recovery handler, so a malformed image triggers libpng's default fatal-error path and terminates the filter process, killing the in-flight print job. No public exploit identified at time of analysis; this is a print-job availability issue, not a code-execution or data-exposure flaw.
Arbitrary file write in pulpcore's FilesystemExport feature allows an authenticated administrator to escape the intended export directory via directory-traversal sequences embedded in a user-controlled relative_path. Because the exported file content is also attacker-supplied (an uploaded artifact), the flaw lets a privileged user plant or overwrite arbitrary files anywhere the Pulp service user can write, enabling service compromise or broader host takeover. Rated CVSS 9.0 and reported by Red Hat, it affects pulpcore as embedded in Ansible Automation Platform 2, Satellite 6, and Red Hat Update Infrastructure 4/5; there is no public exploit identified at time of analysis.
Local privilege escalation to root in the QEMU Guest Agent (qga) affects Red Hat Enterprise Linux 6 through 10, RHEL for NVIDIA 26, and OpenShift Container Platform 4, where a local unprivileged guest user abuses the guest-ssh-add-authorized-keys command handler through symlink manipulation to seize ownership of arbitrary root-owned files. Two attack variants exist - a deterministic directory-symlink bypass and a TOCTOU file-symlink race - both requiring an external management layer such as libvirt to invoke the code path. No public exploit is identified at time of analysis and it is not listed in CISA KEV, but the CVSS 7.3 rating and clean path to full root access make it a meaningful local escalation risk in multi-tenant virtualization estates.
Out-of-bounds heap write in the freedesktop xdgmime library (bundled with GLib-based MIME detection) allows a local attacker to crash or corrupt the memory of any application that guesses content types via g_content_type_guess(). The flaw lives in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c and triggers on little-endian systems when a maliciously crafted MIME magic file placed in a user-writable XDG data location is parsed, producing a 2-byte out-of-bounds write. Red Hat rates it 7.1 (Important); no public exploit is identified at time of analysis and it is not listed in CISA KEV.
Sandbox escape in PipeWire's PulseAudio compatibility layer lets a low-privileged process inside a confined environment such as Flatpak load an attacker-controlled library and execute arbitrary code on the host user's session. The flaw (CWE-427) is present in PipeWire as shipped in Red Hat Enterprise Linux 7, 8, 9 and 10 and carries a scope-changing CVSS 3.1 score of 8.8. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in libsolv's PGP signature verification (solv_pgpvrfy) allows remote attackers to crash automated package and repository processing by supplying a crafted Ed25519 signature. The flaw is a stack-based buffer overflow (CWE-121) triggered when the EdDSA 's' MPI is copied into a fixed 64-byte stack buffer using an attacker-controlled mismatched length. It affects the libsolv dependency solver embedded in Red Hat Enterprise Linux 7/8/9/10, OpenShift, Satellite, RHUI, openSUSE/SUSE, Ubuntu and Debian; no public exploit identified at time of analysis and it is not in CISA KEV.
Access-control bypass in Keycloak (fixed in 26.5.3) lets a disabled user account still obtain valid tokens through the JWT authorization grant preview feature. When that feature is enabled, Keycloak omits the account-enabled check during JWT authorization grant processing, so a low-privileged remote attacker who can present a valid assertion token from an external identity provider can mint a JWT for an account an administrator has explicitly disabled, regaining access to protected resources. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Out-of-bounds heap write in QEMU lets a local attacker operating inside a guest virtual machine corrupt memory in the host emulator process, enabling information disclosure, data-integrity corruption, or denial of service. The flaw stems from cpu_physical_memory_map() returning a shorter buffer length than the caller assumes, so subsequent writes spill past the allocation. Rated CVSS 7.8 (CWE-787); no public exploit identified at time of analysis, but multiple distributions (Red Hat, Ubuntu, SUSE, Debian) have shipped fixes.
Denial of service in the Feast Feature Server (the Python feature-store serving component, also shipped within Red Hat OpenShift AI/RHOAI) lets remote unauthenticated attackers exhaust host resources through its `/ws/chat` WebSocket endpoint. Because the endpoint accepts unlimited concurrent connections and unbounded message traffic, opening many simultaneous sockets drains memory, CPU, and file descriptors until legitimate clients are locked out. There is no public exploit identified at time of analysis and this is not listed in CISA KEV; the upstream fix in PR #192 caps connections, message size, and message rate.
mTLS authentication bypass in the Red Hat Ansible Automation Platform (AAP) Gateway Envoy proxy allows unauthenticated remote attackers to inject spoofed events into protected Event-Driven Ansible (EDA) event streams. The non-mTLS route to EDA event streams fails to strip the client-supplied Subject HTTP header even though the source defines requestHeadersToRemove for it, so an attacker can forge a Subject value matching a legitimate client certificate's Distinguished Name and impersonate an authenticated client. No public exploit identified at time of analysis; the issue is tracked by Red Hat (CWE-290, CVSS 8.2) but is not on CISA KEV and no EPSS score was provided.
Privilege escalation in CRI-O (the OCI container runtime used by Red Hat OpenShift Container Platform 4 and many Kubernetes clusters) lets an attacker who can set container environment variables inject a newline into the HOME variable and append arbitrary lines to /etc/passwd, enabling creation of a rootful or otherwise privileged account inside the container. It is a bypass of the incomplete fix for CVE-2022-4318, whose HOME sanitization was insufficient. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in Red Hat OpenShift GitOps (Argo CD operator) lets a tenant who controls a namespace-scoped Argo CD instance delete a ClusterRole belonging to a cluster-scoped Argo CD instance by crafting a name collision. Because the ClusterRole reconciler skips ownership validation (CWE-862), a low-privileged tenant can disrupt a higher-privileged, cluster-wide GitOps instance across the trust boundary. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the cross-tenant scope change makes it a meaningful multi-tenancy integrity concern.
Remote denial of service in libsoup, the GNOME HTTP client/server library, allows unauthenticated attackers to crash any application using libsoup's WebSocket support by sending a single malformed control frame. The parser fails to enforce RFC 6455's 125-byte limit on PING/PONG/CLOSE control frames and mishandles the oversized payload instead of cleanly closing the connection, causing an internal processing crash. Red Hat reports the flaw across RHEL 6 through 10; no public exploit has been identified at time of analysis and no EPSS score was provided.
Denial of service in libsoup's WebSocket permessage-deflate implementation lets a remote, unauthenticated attacker crash applications by sending a small, highly compressed 'decompression bomb' that expands without bound during inflation, exhausting memory and triggering an Out-of-Memory kill. All Red Hat Enterprise Linux 6 through 10 ship the affected libsoup HTTP/WebSocket library, and client connections are especially exposed because the decompressed-size guard (max_total_message_size) is disabled by default for clients. There is no public exploit identified at time of analysis and this CVE is not listed in CISA KEV.
Remote code execution in the Argo CD repo-server component (as shipped in Red Hat OpenShift GitOps and the argoproj argo-helm chart) allows an unauthenticated attacker with network access to the repo-server to run arbitrary code and, under certain conditions, poison cached manifests to push malicious Kubernetes resources into managed clusters, enabling full cluster takeover. The root cause is missing authentication (CWE-306) on a critical internal service that the default Helm chart left network-exposed. There is no public exploit identified at time of analysis, but detailed third-party technical research (Synacktiv) and press coverage exist, and the flaw was reported unpatched at disclosure.
Privilege escalation in Red Hat OpenShift's incluster-checks diagnostic tool lets any authenticated user holding the standard 'edit' RBAC role escalate to root on the underlying cluster nodes. The tool provisions privileged debug pods with host-filesystem access inside the shared default namespace, so a low-privileged tenant can simply exec into an existing pod and break out to the host. No public exploit identified at time of analysis, and no CISA KEV listing; EPSS data was not provided in the source intelligence.
Sensitive information disclosure in Red Hat OpenShift AI's vllm-orchestrator-gateway component exposes bearer tokens and full chat payloads because the production binary writes all incoming Authorization headers and complete request bodies to persistent logs. Any user holding logging privileges can read these logs to harvest live credentials and potentially PII-laden conversation content. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Server-side request forgery in the file_type content detector of guardrails-detectors (a component shipped with Red Hat OpenShift AI/RHOAI) allows a remote attacker to submit an arbitrary XML Schema Definition (XSD) that the parser resolves without restriction, coercing the server into fetching attacker-chosen URLs or reading local files. Because the CVSS vector is AV:N/PR:N/UI:N with a changed scope and high confidentiality impact (base score 9.3), an unauthenticated attacker can pivot into internal networks and harvest secrets such as cloud provider credentials. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Denial of service in GStreamer's DTLS plugin allows a remote unauthenticated attacker to crash any application that performs a DTLS handshake (notably WebRTC/webrtcbin pipelines) by presenting a TLS certificate with an oversized Subject Distinguished Name. The Subject DN is written into a fixed 2048-byte stack buffer with no bounds checking (CWE-121), and overflowing it corrupts the stack and terminates the process. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; impact is limited to availability (process crash), with no code execution or data exposure claimed.
Heap buffer overflow in GStreamer's rfbsrc (RFB/VNC source) plugin lets a malicious VNC server crash or corrupt the memory of any client that connects to it. When the server advertises a 16bpp framebuffer and sends Hextile-encoded updates, the background-fill path writes 32-bit pixels into a 16-bit buffer, producing an out-of-bounds heap write. No public exploit identified at time of analysis; the primary confirmed impact is denial of service, with potential for further memory corruption. This is a client-side flaw requiring the victim to connect to attacker-controlled infrastructure.
Denial of service in Red Hat / 389 Directory Server (389-ds-base, versions since ~1.3.2/2013) allows an authenticated LDAP client to crash the server by sending an oversized UNBIND packet over a SASL integrity-protected connection. The oversized data overflows a fixed 512-byte heap receive buffer in sasl_io_recv() (sasl_io.c), and in FreeIPA / Red Hat IdM any domain user, enrolled host, or service account with a valid Kerberos ticket can trigger it after GSSAPI authentication. There is no public exploit identified at time of analysis, and this flaw is distinct from the earlier CVE-2025-14905 schema.c overflow, which did not fix this code path.
Privilege escalation to root and Kerberos-based authentication bypass in SSSD's Active Directory GPO provider affects Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. Because ad_gpo_extract_smb_components() fails to sanitize '..' sequences in the gPCFileSysPath LDAP attribute (CWE-23), an actor holding AD GPO management rights can force an SSSD-enrolled host to write attacker-controlled files outside the GPO cache as root, injecting Kerberos configuration to bypass authentication. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Local-to-domain-wide root privilege escalation in SSSD's LDAP sudo provider allows an authenticated LDAP directory user with write access to any subtree to inject a malicious sudoRole object and gain root-level sudo on every SSSD-enrolled host. The flaw exists because, when ldap_sudo_search_base is left unset, SSSD searches the entire directory tree for sudoRole objects, trusting rules planted anywhere in the DIT. Rated CVSS 8.8 by Red Hat and reported against RHEL 6 through 10 and OpenShift Container Platform 4; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Heap memory corruption in GIMP's PSD (Photoshop) file parser allows a malicious .psd image to overflow an integer in read_RLE_channel(), producing an undersized heap allocation for the RLE row-length table that is then overwritten row-by-row, potentially yielding denial of service or arbitrary code execution. The flaw affects GIMP as shipped across Red Hat Enterprise Linux 6 through 9 and is triggered when a victim opens or imports a crafted PSD file. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Stack-based memory corruption in GIMP's PNM image parser lets an attacker execute code or crash the application when a victim opens a malicious PNM/PBM/PGM/PPM file. The flaw is an off-by-one in pnmscanner_gettoken() that writes a null terminator one byte past a stack buffer; it is local and requires the user to open the crafted file (UI:R). No public exploit is identified at time of analysis, and EPSS is low (0.12%), consistent with the CISA SSVC 'Exploitation: none' judgment.
Authenticated denial of service in Red Hat Advanced Cluster Security for Kubernetes (RHACS) 4 allows any user holding a valid API token to exhaust Central's resources. Because Central does not cap the nesting depth of queries served on its authenticated GraphQL API, a single deeply nested query can drive excessive CPU and memory consumption and take down the RHACS management plane. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV, but the low-privilege network vector makes it trivial for any token holder to trigger.
Heap-based buffer overflow in GIMP's Paint Shop Pro (PSP) image format parser lets an attacker achieve arbitrary code execution or crash the application when a victim opens a maliciously crafted PSP file. The flaw stems from incorrect buffer-size arithmetic on low bit-depth images, and affects GIMP as shipped across Red Hat Enterprise Linux 6 through 9. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; exploitation requires local file-open interaction (CVSS 7.3).
Remote code execution and privilege escalation in HPLIP (HP Linux Imaging and Printing) affects the hpcups print filter across Red Hat Enterprise Linux 6 through 10, where an integer overflow triggered by specially crafted print data can corrupt memory. This is an incomplete-fix follow-up to CVE-2026-8631, meaning the original patch did not fully close the flaw, and no public exploit has been identified at time of analysis. The Red Hat CVSS of 9.8 reflects a network-reachable, unauthenticated attack path, though realistic exploitation depends on how the CUPS print pipeline is exposed.
Memory corruption in GIMP's Paint Shop Pro (.psp) import parser lets an attacker crash the application or possibly execute code by persuading a victim to open a crafted PSP image file. The root cause is a double-free (CWE-415) in the read_layer_block() routine; exploitation requires local user interaction to open the file and results in per-user, client-side compromise rather than server-side or unattended exploitation. There is no public exploit identified at time of analysis, the SSVC decision framework rates exploitation as 'none' and automatable as 'no', and EPSS is low at 0.12% (2nd percentile), yet Red Hat tracks the defect across RHEL 6 through 9 and a vendor patch plus an upstream commit are available.
Arbitrary file write in the Feast Feature Server's `/save-document` endpoint lets an unauthenticated remote attacker write attacker-controlled JSON to the host filesystem, bypassing the endpoint's path restrictions to overwrite application configuration or startup scripts. Because no credentials are required (CVSS 9.1, PR:N), any network-reachable attacker can corrupt system integrity, cause denial of service through disk exhaustion, or potentially achieve remote code execution. This flaw also ships in Red Hat OpenShift AI (RHOAI), which bundles Feast; there is no public exploit identified at time of analysis and it is not in CISA KEV.
Privilege escalation in Foreman (the engine behind Red Hat Satellite 6) lets an authenticated user holding usergroup-management permissions attach arbitrary roles - including the administrator role - to a user group and then enroll themselves, gaining full admin-level control. The Usergroup model fails to validate that the assigning user actually holds the roles being granted, breaking the RBAC delegation boundary. Rated CVSS 8.8; no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and clear escalation path make it a strong patch priority.
Denial of service in libarchive's RAR5 reader allows remote attackers to crash applications that decompress untrusted RAR5 archives via a double-free (CWE-415) of the stale filtered_buf pointer. Reported by Red Hat and affecting libarchive as shipped across Red Hat Enterprise Linux 6 through 10, OpenShift Container Platform 4, and Red Hat Hardened Images, the flaw is triggered purely by parsing a malicious archive entry. No public exploit has been identified and the issue is not in CISA KEV; impact is limited to availability (CVSS 7.5, A:H only) with no code execution or data exposure claimed.
Arbitrary VS Code command execution in the Red Hat vscode-java extension allows a malicious Java source file to embed hidden commands inside JavaDoc hover Markdown, so that a developer who simply clicks a crafted link in a hover popup triggers attacker-chosen commands that can escalate to full system compromise in trusted workspaces. The flaw stems from the extension rendering JavaDoc hovers as fully-trusted Markdown, and it also affects Red Hat OpenShift Dev Spaces, which bundles the extension. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the network reach combined with only a single click of user interaction makes it high-impact.
Cross-tenant VM compromise in KubeVirt (and Red Hat OpenShift Virtualization 4) occurs when spec.configuration.migrations.disableTLS is set to true, causing virt-handler to expose an unauthenticated plaintext TCP proxy into a virt-launcher's virtqemud control socket on all interfaces. An authenticated tenant who can run any pod on the cluster network can reach this listener and issue arbitrary libvirt RPC commands against another tenant's virtual machine - reading guest memory, altering VM state via QMP, or destroying the VM. No public exploit identified at time of analysis; not listed in CISA KEV, and no EPSS score was provided.
Server-side request forgery in Red Hat Build of Apicurio Registry 3 allows a Developer-role user to coerce the registry server into issuing HTTP requests to arbitrary internal URLs. The flaw stems from the WSDLReaderAccessor instantiating a wsdl4j WSDLReader with the javax.wsdl.importDocuments feature left enabled, so a crafted WSDL artifact with attacker-controlled import locations is fetched when content validation runs at FULL strictness. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; CVSS is 7.4 (scope-changed) and exploitation requires authenticated low-privilege access plus a non-default validation setting.
Server-side request forgery and denial of service in Red Hat Build of Apicurio Registry 3 stem from unsafe XML parsing in the ContentTypeUtil.isParsableXml() method, which builds a SAXParserFactory without secure processing or external-entity restrictions (CWE-611, XXE). An attacker with artifact-write permission - or any unauthenticated client when the registry runs in its default configuration - can upload a crafted XML artifact whose external DTD/entity references force the server to fetch attacker-chosen URLs (blind SSRF into internal networks) or expand nested entities for resource-exhaustion DoS. CVSS is 8.5 (scope-changed, high availability impact); no public exploit identified at time of analysis.
Signature-verification bypass in Keycloak (and Red Hat's Keycloak-based products such as Red Hat Single Sign-On 7 and Red Hat Build of Keycloak 26.6/26.6.4) lets an attacker holding valid client credentials abuse a JWT algorithm-confusion weakness in the JWT Authorization Grant flow to forge client assertions and mint unauthorized access tokens. The forged tokens allow impersonation of any federated user tied to the affected Identity Provider, yielding unauthorized access and potential privilege escalation. There is no public exploit identified at time of analysis and the issue is not on CISA KEV; Red Hat rates it 8.1 (High).
Stored Cross-Site Scripting in Red Hat Build of Keycloak lets an authenticated administrator with `manage-client` permission (or access to client registration endpoints) register a malicious client whose redirect URI uses a case-insensitive `javascript:` or `data:` scheme, bypassing URI validation. When a victim later clicks a crafted link - for example during the logout flow or within the Admin Console - the script executes in the Keycloak origin, enabling session/token theft and effective code execution in that trusted context. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; it carries a CVSS 7.3 (PR:L, UI:R).
Privilege escalation in Keycloak (Red Hat Build of Keycloak) lets an authenticated delegated admin with management rights over a single low-privilege group hijack the entire realm. A missing authorization check in the Admin REST API's GroupResource.addChild() endpoint allows reparenting an arbitrary group; when Fine-Grained Admin Permissions v2 (FGAPv2) is enabled, an attacker can move a privileged group (e.g., one holding realm-admin) under a group they control, inheriting management and password-reset rights over its members. There is no public exploit identified at time of analysis and the issue is not in CISA KEV, but the resulting full realm takeover makes it a serious escalation primitive in environments that delegate group administration.
Authorization bypass in the Keycloak Policy Enforcer allows any authenticated user to circumvent all enforced access controls - role, scope, and User-Managed Access (UMA) permission checks - by embedding the configured access-denied page path inside a request URL as a path segment or query parameter. The affected component ships in the Red Hat Build of Keycloak, and successful exploitation grants unauthorized access to protected resources. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Session hijacking in the foreman-mcp-server component (shipped with Red Hat Satellite 6) allows local attackers to take over active administrative sessions by reusing leaked session IDs that the server caches without re-validating authentication tokens. Because session IDs are written to standard logs, any user with log read access can replay them to gain administrative control and pivot to infrastructure-wide code execution. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Credential disclosure in Red Hat Ansible Automation Platform 2.5 and 2.6 allows any authenticated user to retrieve plaintext OAuth tokens, vault passwords, and SSH keys by sending forged Worker messages to the Event-Driven Ansible websocket endpoint. The /api/eda/ws/ansible-rulebook endpoint fails to verify permissions on activation_id values, enabling lateral credential theft across tenants. No public exploit identified at time of analysis, but the low attack complexity and scope-changed CVSS of 9.6 make this a high-priority patch.
Credential theft in Red Hat OpenShift Container Platform's Windows Machine Config Operator (WMCO) allows adjacent-network attackers to intercept SSH sessions to Windows worker nodes and steal WICD and kubelet bootstrap credentials. WMCO fails to verify the remote SSH host key when configuring Windows nodes, enabling a man-in-the-middle attacker positioned on the cluster network to capture credentials sufficient to assume Windows node identities. No public exploit identified at time of analysis, and the issue is not in CISA KEV.
Privilege escalation in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform allows a compromised Windows worker node holding WICD credentials to obtain a cluster-administrator client certificate. The WICD CSR auto-approver checks for the system:wicd-nodes organization but fails to reject additional organization values such as system:masters, enabling full cluster takeover. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in the cifs-utils cifs.upcall helper allows low-privileged Linux users to gain root by abusing the kernel request_key interface to load a malicious NSS module inside an attacker-controlled mount namespace. The root-owned helper fails to drop privileges before performing user-name resolution, so the attacker's NSS module executes with full root capabilities. No public exploit identified at time of analysis, but the bug affects every supported Red Hat Enterprise Linux release (6 through 10) and OpenShift Container Platform 4, making it a high-priority hardening fix for any host with CIFS/SMB client functionality.
Remote code execution in galaxy_ng's legacy role import API (v1) allows an authenticated user controlling a git repository to execute arbitrary commands on the pulp worker by crafting a branch or tag name containing shell metacharacters. The flaw stems from unsanitized git ref interpolation into a subprocess.run() call with shell=True inside do_git_checkout(), and only affects deployments where GALAXY_ENABLE_LEGACY_ROLES is explicitly enabled (non-default). No public exploit identified at time of analysis.
Heap buffer overflow in GNOME localsearch (formerly tracker-miners) tracker-extract-mp3 component on Red Hat Enterprise Linux 8/9/10, Ubuntu, Debian, and SUSE allows remote attackers to trigger an out-of-bounds heap read by delivering a malformed MP3 file with crafted ID3 performer tags, leading to crashes (DoS) or disclosure of process memory contents. No public exploit identified at time of analysis, and the EPSS score of 0.19% (9th percentile) plus CISA SSVC 'Exploitation: none' indicate low real-world exploitation activity despite the 8.1 CVSS rating. Vendor patches are available across Red Hat (RHSA), Ubuntu USN-8019-1, Debian, and SUSE-SU-2026:0780/21854.
Out-of-bounds read in GStreamer's VMnc decoder allows remote attackers to crash the application or disclose memory contents when a victim opens a maliciously crafted VMnc video file. The flaw stems from a signed integer overflow in payload-size arithmetic that bypasses a length check when cursor dimensions are abnormally large. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Heap buffer overflow in GStreamer's librfb (RFB/VNC client) allows a malicious VNC server to corrupt heap memory on a connecting client, potentially leading to remote code execution or denial of service. The flaw stems from validating rectangle area instead of individual dimensions, letting attacker-controlled rectangles extend beyond the framebuffer. No public exploit identified at time of analysis, though the issue affects GStreamer as shipped across Red Hat Enterprise Linux 6 through 10.
Out-of-bounds read and denial-of-service in GStreamer's RealMedia demuxer (gst-plugins-ugly) allows remote attackers to crash, hang, or potentially leak limited adjacent memory when a victim opens a maliciously crafted RealMedia (.rm) file. The flaw stems from unvalidated offsets in re_skip_pascal_string() and an attacker-controlled loop counter in the FILEINFO metadata parser. No public exploit identified at time of analysis, and the CVE is not on the CISA KEV list.
Out-of-bounds read in the GStreamer RealMedia demuxer (gst-plugins-ugly) allows a maliciously crafted .rm file to crash the consuming application and potentially leak small amounts of adjacent heap memory through stream metadata. The flaw affects Red Hat Enterprise Linux 7, 8, 9, and 10 systems shipping the vulnerable demuxer, and exploitation requires a user to open or otherwise process the file (UI:R). There is no public exploit identified at time of analysis, and the issue is not on the CISA KEV list.
Heap memory corruption in the WavPack audio decoder of GStreamer's gst-plugins-good package allows remote attackers to crash applications or potentially achieve arbitrary code execution when a victim opens a malicious WavPack (.wv) audio file. The flaw, tracked as CVE-2026-53705 and reported by Red Hat, affects Red Hat Enterprise Linux versions 7, 8, 9, and 10, and stems from an integer overflow during buffer size calculation that produces an undersized heap allocation later overrun by decoded samples. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the multimedia decoder attack surface combined with RCE potential makes it a meaningful patching priority.
Out-of-bounds read in the VA JPEG decoder shipped in GStreamer's gst-plugins-bad allows a remote attacker to crash the decoder or potentially leak adjacent memory contents when a victim opens a maliciously crafted JPEG file. The flaw stems from the JPEG parser trusting a segment-length value from the bitstream without verifying it fits within the buffer, and affects Red Hat Enterprise Linux 6 through 10 where the plugin is consumed. There is no public exploit identified at time of analysis and the issue is not in CISA KEV.
Local privilege escalation via arbitrary root-owned file overwrite affects libreport's ABRT post-create event handler scripts on Red Hat Enterprise Linux 6, 7, and 8. The event scripts write output using shell redirections that lack the O_NOFOLLOW flag, so a local low-privileged user who plants a symlink in a writable crash-dump path can cause the root shell to follow it and clobber any file on the system, which can be leveraged for full system compromise. SSVC rates technical impact as total, but there is no public exploit identified at time of analysis and EPSS is negligible (0.02%, 5th percentile).
Local privilege escalation in the abrt-dbus D-Bus service on Red Hat Enterprise Linux 6, 7, and 8 allows a low-privileged local user to race the ChownProblemDir method against still-running post-create event handlers. By invoking ChownProblemDir while privileged event scripts hold a write lock on the dump directory, the attacker gains filesystem ownership of files being written by root-context handlers, enabling tampering with privileged output and potential privilege escalation. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in the abrt-dbus D-Bus service on Red Hat Enterprise Linux 6, 7, and 8 allows any unprivileged local user to win a TOCTOU race against the SetElement method, writing arbitrary text files into root-owned dump directories. By exploiting the gap between dump directory creation and post-create event execution, an attacker bypasses package validation and persists crash data for unpackaged binaries inside privileged paths, with no public exploit identified at time of analysis.
Heap buffer overflow in 389 Directory Server (389-ds-base) SASL I/O layer allows authenticated remote attackers to crash the LDAP service or achieve remote code execution after a successful SASL bind with integrity protection (SSF > 0). The flaw stems from an integer overflow in sasl_io_start_packet() that bypasses the nsslapd-maxsasliosize ceiling, enabling roughly 2 MB of attacker-controlled heap corruption. No public exploit identified at time of analysis, and the impact is amplified in FreeIPA and Red Hat Identity Management deployments where any enrolled user, host, or service principal qualifies as an authenticated attacker.
Root command injection in dracut's legacy DHCP path allows adjacent-network attackers to execute arbitrary commands inside the initramfs by sending crafted DHCP options (e.g., malicious hostname) that are written unescaped into temporary shell scripts. The flaw affects Red Hat Enterprise Linux 6 through 10, Red Hat Hardened Images, and OpenShift Container Platform 4, granting full system compromise during early boot. No public exploit identified at time of analysis, and EPSS is low (0.16%, 36th percentile), but SSVC rates technical impact as total.
Remote denial of service in 389 Directory Server (Red Hat Directory Server 11/12/13 and Red Hat Enterprise Linux 6 through 10) allows unauthenticated network attackers to crash the LDAP daemon by exploiting an unchecked BER structure allocation in the dereference control plugin when the host is under memory pressure. No public exploit identified at time of analysis, and EPSS exploitation probability is very low (0.09%, 25th percentile), but the unauthenticated network-reachable nature warrants prompt patching of internet-facing or business-critical directory services.
Privilege escalation in Keycloak allows a limited administrator to become a full realm administrator by importing users with realm-admin role mappings via the POST /admin/realms/{realm}/partialImport endpoint, bypassing Fine-Grained Admin Permissions (FGAP). Exploitation requires a high-privilege authenticated user, and while a proof-of-concept exploit exists, the EPSS score is very low (0.03%) and there is no evidence of active exploitation.
Out-of-bounds heap write in X.Org X server and Xwayland DRI2 buffer handling allows a local authenticated client to corrupt server memory by requesting multiple DRI2BufferBackLeft attachments alongside one DRI2BufferFrontLeft. Successful exploitation crashes the display server or, when the X server runs setuid root (a still-common legacy deployment), enables local privilege escalation to root. No public exploit is identified at time of analysis and the issue is not listed in CISA KEV.
Local privilege escalation in the X.Org X server and Xwayland arises from a use-after-free in SyncChangeCounter() that a local authenticated attacker can trigger by orchestrating two client connections - one creating multiple SyncCounters, the other destroying them while they are being changed. On systems where the X server still runs as root (common on legacy Linux setups), successful exploitation yields root code execution; at minimum it crashes the display server. No public exploit identified at time of analysis, but the bug is confirmed by Red Hat and a fix has landed upstream in xserver.
Local privilege escalation in the X.Org X server and Xwayland arises from a use-after-free in FreeCounter() when SyncCounter objects are destroyed across multiple client connections. Authenticated local attackers on affected Red Hat Enterprise Linux 6 through 10 systems can crash the server or escalate to root when the X server runs with elevated privileges. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in X.Org X server and Xwayland stems from an incomplete fix for CVE-2025-26597, where CheckKeyTypes() fails to clamp non-canonical key types to XkbMaxShiftLevel, enabling stack-based buffer overflows. Authenticated local users on Red Hat Enterprise Linux 6 through 10 can crash the display server or, when X runs as root, escalate to root privileges. No public exploit identified at time of analysis, though the upstream commit reveals the vulnerable code path and the prior CVE-2025-26597 has known exploitation history.
Stack-based buffer overflow in X.Org X server and Xwayland's _XkbSetMapChecks() function allows local authenticated attackers to crash the server or potentially escalate privileges to root when the X server runs with elevated privileges. The flaw resides in CheckKeyTypes() writing to a fixed mapWidths[256] stack buffer at a client-controlled offset, affecting Red Hat Enterprise Linux versions 6 through 10. No public exploit identified at time of analysis, but an upstream fix has been merged into the xserver repository.
Local privilege escalation in the X.Org X server and Xwayland stems from a stack-based buffer overflow during font alias resolution, where a 256-byte server-side stack buffer is overrun by libXfont2 alias target names of up to 1023 bytes. An authenticated local attacker who can influence font alias files can crash the server or, when the X server runs as root, escalate to root privileges. No public exploit is identified at time of analysis and CVSS is 7.8 (Local/Low complexity/Low privileges).
Local privilege escalation in X.Org X server and Xwayland enables authenticated local users to trigger a use-after-free in miSyncDestroyFence() by racing two client connections against a shared fence object. Successful exploitation can crash the display server or escalate privileges to root when the X server runs as root, which remains common on legacy and embedded Linux deployments. No public exploit identified at time of analysis, but an upstream fix has been committed by the X.Org maintainers.
Deploy-time policy bypass in Red Hat Advanced Cluster Security for Kubernetes 4 lets a user with Kubernetes Deployment-create permission spoof workload identity by setting the openshift.io/encoded-deployment-config label to "null", forcing ACS to record the workload with empty UID, name and labels and a "default" namespace. This evades ACS deploy-time policy detection and enforcement visibility and corrupts Central's persistence, violation reporting and compliance correlation. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Token exchange in Keycloak bypasses Google Workspace domain allowlist restrictions, enabling any valid Google account holder - regardless of their domain - to swap a Google OAuth token for a Keycloak realm token and gain unauthorized access. Affected deployments are those specifically configured to restrict Google-based logins to approved Workspace domains while also having token exchange enabled; both conditions must be present. No public exploit code has been identified at time of analysis, and EPSS sits at 0.20% (10th percentile), consistent with SSVC's exploitation status of 'none', though SSVC rates technical impact as 'total' given that successful exploitation delivers full realm access.
Tenant-restriction bypass in Keycloak's Microsoft identity provider integration allows attackers holding any valid Microsoft OAuth token - even from a completely unrelated Azure AD organization - to authenticate into a Keycloak realm via the token exchange feature. Affected deployments include Red Hat Build of Keycloak, Red Hat Single Sign-On 7, and Red Hat JBoss EAP Expansion Pack. With CVSS PR:L reflecting the need for a valid Microsoft credential (trivially obtained by registering a free Azure tenant), successful exploitation grants high confidentiality and integrity impact within the realm. No public exploit or active exploitation has been identified at time of analysis; EPSS sits at 0.19% (9th percentile), consistent with SSVC exploitation=none.
Local privilege escalation to root via argument injection in the APT backend of yggdrasil-worker-package-manager, the Red Hat Insights remote package-management worker shipped with Red Hat Enterprise Linux 10. Because package names are passed directly to apt-get without an argument terminator, a name beginning with a hyphen is parsed as a command-line option rather than a package, letting an attacker who can influence the package list achieve root-level remote code execution. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but an upstream source fix is already merged and released in versions 0.1.4 and 0.2.4.
Confidential Active Directory attribute disclosure in Samba's Active Directory Domain Controller allows an authenticated low-privilege domain user to read protected directory attributes by abusing how LDAP Compare requests are handled. Because Samba fails to validate user-supplied attribute names (LDAP filter injection, CWE-90) and runs the resulting internal search in a trusted context, normal ACL enforcement is bypassed; in gMSA-enabled deployments this permits extraction of msKds-RootKeyData and offline derivation of Group Managed Service Account passwords, which can escalate to full domain compromise. No public exploit identified at time of analysis and the issue is not listed in CISA KEV, but a vendor patch is available.
Remote unauthenticated denial of service in Performance Co-Pilot (PCP), the system performance monitoring toolkit shipped with Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4, allows an attacker to permanently disable a PCP daemon by triggering a signed integer overflow (CWE-190) in the __pmGetPDU() PDU-length handling routine. A crafted network packet sent during normal PDU processing or SASL authentication negotiation corrupts the read logic so that the daemon can no longer read any subsequent packets, requiring a manual restart. There is no public exploit identified at time of analysis and the flaw yields no code execution or data exposure - impact is availability-only (CVSS 7.5, A:H).
Remote unauthenticated access-control bypass in the Performance Co-Pilot (PCP) pmproxy component lets attackers reach the /store endpoint and overwrite arbitrary PMDA (Performance Metrics Domain Agent) metric values, which the reporter (Red Hat) states can escalate to arbitrary code execution and full system takeover. The flaw affects PCP as shipped across Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the network-reachable, no-authentication attack surface makes exposed pmproxy instances a meaningful risk.
Local privilege escalation in Performance Co-Pilot (PCP) on Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4 arises from the linux_sockets module exposing an unsecured internal connection. An attacker who already holds low-level code execution on the host can leverage this leaked/unprotected socket to run arbitrary commands as root. No public exploit has been identified at time of analysis and the flaw is not in CISA KEV, so exploitation would require an existing foothold rather than remote unauthenticated access.
Local privilege-relevant command injection in Performance Co-Pilot's (PCP) linux_sockets PMDA lets an authenticated user inject shell metacharacters through the network.persocket.filter metric, causing arbitrary commands to run as the PMDA user each time metrics refresh. Reported by Red Hat, it affects the pcp packages shipped across Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Robot account token disclosure in Red Hat Quay 3 allows a user assigned to the GLOBAL_READONLY_SUPER_USERS role to read the tokens of robot accounts belonging to repositories they are not a member of. Because these tokens are long-lived registry credentials, the read-only superuser can escalate a view-only role into full impersonation of any robot account, gaining whatever push/pull and repository permissions that robot holds. No public exploit identified at time of analysis; not listed in CISA KEV.
Out-of-bounds write in GNU binutils' BFD library (bfd/elf32-dlx.c) lets a crafted ELF/DLX object file corrupt memory and achieve arbitrary code execution when parsed by any BFD-consuming tool (objdump, readelf, strip, ld, nm, objcopy). Reported by Red Hat and tracked against RHEL 6-10, Hardened Images and OpenShift 4, the flaw is only reachable when binutils is compiled with the DLX backend (typically --enable-targets=all), so exposure is gated by a non-default build option. There is no public exploit identified at time of analysis (not in CISA KEV), though the researcher demonstrated code execution via a File Stream Oriented Programming (FSOP) attack on glibc FILE structures.
Privilege escalation in CRIU allows a malicious container process to spoof credentials during checkpoint, resulting in elevated capabilities upon restore. On Red Hat platforms, effective exploitation is mitigated by mandatory access controls, user namespaces, and the requirement for privileged checkpoint initiation. No public exploit identified at time of analysis.
Arbitrary command execution as root via udev property injection in sg3_utils when sg_inq --export parses a SCSI device with a crafted name string. Affects multiple Red Hat Enterprise Linux versions shipping sg3_utils. Publicly available exploit code exists as a proof-of-concept in the upstream fix; no active exploitation has been reported.
Identity header smuggling in OpenShift Container Platform 4.x allows authenticated low-privilege users to escalate privileges by injecting forged identity headers that upstream applications may trust. The oauth-proxy fails to strip underscore-variant headers, enabling WSGI and PHP frameworks to normalize them into the legitimate identity, potentially overriding the true authenticated user. No known active exploitation or public exploit code has been identified.
Header injection in the cluster-proxy service-proxy component of Red Hat Advanced Cluster Management for Kubernetes (RHACM) and multicluster-engine (MCE) allows an authenticated hub principal to escalate to cluster-admin across all managed spoke clusters. The service-proxy forwards Kubernetes impersonation group headers to spoke clusters without stripping caller-supplied values first; because the spoke ServiceAccount holds unrestricted impersonation rights, an injected Impersonate-Group header (e.g., system:masters) is honored by every downstream cluster API server. No public exploit has been identified at time of analysis, and EPSS sits at 0.23%, though SSVC rates technical impact as total given the blast radius across the entire managed fleet.
Denial of service in OpenPrinting libcupsfilters (as shipped in Red Hat Enterprise Linux 7 through 10) allows a network-adjacent attacker to pin a CPU at 100% by broadcasting a crafted printer advertisement. The flaw lies in cfIEEE1284NormalizeMakeModel(), which enters an infinite loop (CWE-835) when parsing an IEEE-1284 device ID whose model field is empty. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; impact is limited to availability with no data compromise.
Authentication bypass in the odh-dashboard web console of Red Hat OpenShift AI (RHOAI) lets a low-privileged actor already inside the cluster impersonate any user — including cluster administrators — by supplying an arbitrary access token to a component that was incorrectly bound to a reachable network interface. Because the impersonated identity is honored against the Kubernetes API, this escalates to arbitrary code execution, privilege escalation, and information disclosure across the cluster. There is no public exploit identified at time of analysis, no CISA KEV listing, and no EPSS score was provided, but the CVSS 8.8 (High) rating and full C/I/A impact make it a serious internal-threat priority.
Local code execution in the Visual Studio Code Ansible (Lightspeed) extension lets a malicious project run arbitrary shell commands on a developer's machine by abusing the ansible.executionEnvironment.containerOptions and volumeMounts settings, which fail to sanitize shell separators (CWE-78). Because these are workspace-scoped settings, simply opening a booby-trapped repository can auto-trigger execution during Language Server initialization, yielding code execution as the VS Code user. No public exploit has been identified at time of analysis, and the flaw is not listed in CISA KEV; CVSS is 7.8 (High).
Arbitrary command execution in ansible-core allows an attacker who controls a collection source URI to run commands on a victim's machine when that victim executes 'ansible-galaxy collection install' against the malicious git source. The flaw lives in _extract_collection_from_git() in concrete_artifact_manager.py, which builds git clone commands without a '--' end-of-options separator, letting crafted URIs be parsed as git arguments. It is an incomplete fix for CVE-2026-11332, which patched the analogous role-install path but left the collection-install path exposed; there is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Privilege escalation via authentication bypass in libssh affects servers that enable GSSAPIKeyExchange, where the gssapi-keyex authentication path fails to confirm that the authenticated Kerberos principal is actually authorized for the local user account being requested. An already-authenticated client holding any valid Kerberos principal in the realm can therefore log in as an arbitrary user, including potentially privileged accounts, on Red Hat Enterprise Linux 8, 9, and 10 and Red Hat Hardened Images. No public exploit is identified at time of analysis and the issue is not listed in CISA KEV, but the CVSS of 8.8 reflects a straightforward, low-complexity abuse once a valid Kerberos credential is held.
Denial of service (and potential use-after-free) in libssh occurs when the library processes SSH data packets that arrive after a channel has been closed, causing channel data callbacks to fire against already-freed memory. Any application or system linking the affected libssh - including Red Hat Enterprise Linux 8, 9, and 10 and Red Hat Hardened Images - can be crashed by a malicious SSH peer that sends channel data at the wrong point in the connection lifecycle. There is no public exploit identified at time of analysis, EPSS is low (0.26%), and CISA SSVC scores exploitation as none, indicating a real but non-urgent memory-safety fix.
Denial of service in libssh affects clients that use automatic certificate-based public key authentication, where logic errors cause the client to loop indefinitely when configured certificates are absent or are repeatedly rejected by the SSH server. Reported by Red Hat and shipped in Red Hat Enterprise Linux 8, 9, and 10 plus Red Hat Hardened Images, the flaw lets a hostile or misconfigured server hang a connecting client and consume CPU. There is no public exploit identified at time of analysis, and EPSS is low at 0.17% (7th percentile), consistent with an availability-only, client-side bug rather than a mass-exploited issue.
Integrity-protection bypass in libssh builds compiled against the OpenSSL crypto backend, caused by incorrect AES-GCM finalization checks that fail to verify the authentication tag. An in-path (man-in-the-middle) attacker positioned on an SSH session can silently alter plaintext bytes on the wire without triggering a MAC/integrity failure, defeating a core guarantee of the SSH transport layer. There is no public exploit identified at time of analysis, EPSS risk is low (0.28%, 20th percentile), and CISA SSVC rates exploitation as 'none' though 'automatable: yes'.
Denial of service in libcupsfilters and cups-filters (the OpenPrinting image-filtering stack bundled with Red Hat Enterprise Linux 7 through 10) allows an unauthenticated attacker to abort the CUPS image filter by submitting a specially crafted PNG print job. The PNG reader instantiates a libpng decoder without registering an error-recovery handler, so a malformed image triggers libpng's default fatal-error path and terminates the filter process, killing the in-flight print job. No public exploit identified at time of analysis; this is a print-job availability issue, not a code-execution or data-exposure flaw.
Arbitrary file write in pulpcore's FilesystemExport feature allows an authenticated administrator to escape the intended export directory via directory-traversal sequences embedded in a user-controlled relative_path. Because the exported file content is also attacker-supplied (an uploaded artifact), the flaw lets a privileged user plant or overwrite arbitrary files anywhere the Pulp service user can write, enabling service compromise or broader host takeover. Rated CVSS 9.0 and reported by Red Hat, it affects pulpcore as embedded in Ansible Automation Platform 2, Satellite 6, and Red Hat Update Infrastructure 4/5; there is no public exploit identified at time of analysis.
Local privilege escalation to root in the QEMU Guest Agent (qga) affects Red Hat Enterprise Linux 6 through 10, RHEL for NVIDIA 26, and OpenShift Container Platform 4, where a local unprivileged guest user abuses the guest-ssh-add-authorized-keys command handler through symlink manipulation to seize ownership of arbitrary root-owned files. Two attack variants exist - a deterministic directory-symlink bypass and a TOCTOU file-symlink race - both requiring an external management layer such as libvirt to invoke the code path. No public exploit is identified at time of analysis and it is not listed in CISA KEV, but the CVSS 7.3 rating and clean path to full root access make it a meaningful local escalation risk in multi-tenant virtualization estates.
Out-of-bounds heap write in the freedesktop xdgmime library (bundled with GLib-based MIME detection) allows a local attacker to crash or corrupt the memory of any application that guesses content types via g_content_type_guess(). The flaw lives in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c and triggers on little-endian systems when a maliciously crafted MIME magic file placed in a user-writable XDG data location is parsed, producing a 2-byte out-of-bounds write. Red Hat rates it 7.1 (Important); no public exploit is identified at time of analysis and it is not listed in CISA KEV.
Sandbox escape in PipeWire's PulseAudio compatibility layer lets a low-privileged process inside a confined environment such as Flatpak load an attacker-controlled library and execute arbitrary code on the host user's session. The flaw (CWE-427) is present in PipeWire as shipped in Red Hat Enterprise Linux 7, 8, 9 and 10 and carries a scope-changing CVSS 3.1 score of 8.8. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV.
Denial of service in libsolv's PGP signature verification (solv_pgpvrfy) allows remote attackers to crash automated package and repository processing by supplying a crafted Ed25519 signature. The flaw is a stack-based buffer overflow (CWE-121) triggered when the EdDSA 's' MPI is copied into a fixed 64-byte stack buffer using an attacker-controlled mismatched length. It affects the libsolv dependency solver embedded in Red Hat Enterprise Linux 7/8/9/10, OpenShift, Satellite, RHUI, openSUSE/SUSE, Ubuntu and Debian; no public exploit identified at time of analysis and it is not in CISA KEV.
Access-control bypass in Keycloak (fixed in 26.5.3) lets a disabled user account still obtain valid tokens through the JWT authorization grant preview feature. When that feature is enabled, Keycloak omits the account-enabled check during JWT authorization grant processing, so a low-privileged remote attacker who can present a valid assertion token from an external identity provider can mint a JWT for an account an administrator has explicitly disabled, regaining access to protected resources. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Out-of-bounds heap write in QEMU lets a local attacker operating inside a guest virtual machine corrupt memory in the host emulator process, enabling information disclosure, data-integrity corruption, or denial of service. The flaw stems from cpu_physical_memory_map() returning a shorter buffer length than the caller assumes, so subsequent writes spill past the allocation. Rated CVSS 7.8 (CWE-787); no public exploit identified at time of analysis, but multiple distributions (Red Hat, Ubuntu, SUSE, Debian) have shipped fixes.
Denial of service in the Feast Feature Server (the Python feature-store serving component, also shipped within Red Hat OpenShift AI/RHOAI) lets remote unauthenticated attackers exhaust host resources through its `/ws/chat` WebSocket endpoint. Because the endpoint accepts unlimited concurrent connections and unbounded message traffic, opening many simultaneous sockets drains memory, CPU, and file descriptors until legitimate clients are locked out. There is no public exploit identified at time of analysis and this is not listed in CISA KEV; the upstream fix in PR #192 caps connections, message size, and message rate.
mTLS authentication bypass in the Red Hat Ansible Automation Platform (AAP) Gateway Envoy proxy allows unauthenticated remote attackers to inject spoofed events into protected Event-Driven Ansible (EDA) event streams. The non-mTLS route to EDA event streams fails to strip the client-supplied Subject HTTP header even though the source defines requestHeadersToRemove for it, so an attacker can forge a Subject value matching a legitimate client certificate's Distinguished Name and impersonate an authenticated client. No public exploit identified at time of analysis; the issue is tracked by Red Hat (CWE-290, CVSS 8.2) but is not on CISA KEV and no EPSS score was provided.
Privilege escalation in CRI-O (the OCI container runtime used by Red Hat OpenShift Container Platform 4 and many Kubernetes clusters) lets an attacker who can set container environment variables inject a newline into the HOME variable and append arbitrary lines to /etc/passwd, enabling creation of a rootful or otherwise privileged account inside the container. It is a bypass of the incomplete fix for CVE-2022-4318, whose HOME sanitization was insufficient. No public exploit identified at time of analysis and it is not listed in CISA KEV.
Denial of service in Red Hat OpenShift GitOps (Argo CD operator) lets a tenant who controls a namespace-scoped Argo CD instance delete a ClusterRole belonging to a cluster-scoped Argo CD instance by crafting a name collision. Because the ClusterRole reconciler skips ownership validation (CWE-862), a low-privileged tenant can disrupt a higher-privileged, cluster-wide GitOps instance across the trust boundary. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the cross-tenant scope change makes it a meaningful multi-tenancy integrity concern.
Remote denial of service in libsoup, the GNOME HTTP client/server library, allows unauthenticated attackers to crash any application using libsoup's WebSocket support by sending a single malformed control frame. The parser fails to enforce RFC 6455's 125-byte limit on PING/PONG/CLOSE control frames and mishandles the oversized payload instead of cleanly closing the connection, causing an internal processing crash. Red Hat reports the flaw across RHEL 6 through 10; no public exploit has been identified at time of analysis and no EPSS score was provided.
Denial of service in libsoup's WebSocket permessage-deflate implementation lets a remote, unauthenticated attacker crash applications by sending a small, highly compressed 'decompression bomb' that expands without bound during inflation, exhausting memory and triggering an Out-of-Memory kill. All Red Hat Enterprise Linux 6 through 10 ship the affected libsoup HTTP/WebSocket library, and client connections are especially exposed because the decompressed-size guard (max_total_message_size) is disabled by default for clients. There is no public exploit identified at time of analysis and this CVE is not listed in CISA KEV.
Remote code execution in the Argo CD repo-server component (as shipped in Red Hat OpenShift GitOps and the argoproj argo-helm chart) allows an unauthenticated attacker with network access to the repo-server to run arbitrary code and, under certain conditions, poison cached manifests to push malicious Kubernetes resources into managed clusters, enabling full cluster takeover. The root cause is missing authentication (CWE-306) on a critical internal service that the default Helm chart left network-exposed. There is no public exploit identified at time of analysis, but detailed third-party technical research (Synacktiv) and press coverage exist, and the flaw was reported unpatched at disclosure.
Privilege escalation in Red Hat OpenShift's incluster-checks diagnostic tool lets any authenticated user holding the standard 'edit' RBAC role escalate to root on the underlying cluster nodes. The tool provisions privileged debug pods with host-filesystem access inside the shared default namespace, so a low-privileged tenant can simply exec into an existing pod and break out to the host. No public exploit identified at time of analysis, and no CISA KEV listing; EPSS data was not provided in the source intelligence.
Sensitive information disclosure in Red Hat OpenShift AI's vllm-orchestrator-gateway component exposes bearer tokens and full chat payloads because the production binary writes all incoming Authorization headers and complete request bodies to persistent logs. Any user holding logging privileges can read these logs to harvest live credentials and potentially PII-laden conversation content. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Server-side request forgery in the file_type content detector of guardrails-detectors (a component shipped with Red Hat OpenShift AI/RHOAI) allows a remote attacker to submit an arbitrary XML Schema Definition (XSD) that the parser resolves without restriction, coercing the server into fetching attacker-chosen URLs or reading local files. Because the CVSS vector is AV:N/PR:N/UI:N with a changed scope and high confidentiality impact (base score 9.3), an unauthenticated attacker can pivot into internal networks and harvest secrets such as cloud provider credentials. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Denial of service in GStreamer's DTLS plugin allows a remote unauthenticated attacker to crash any application that performs a DTLS handshake (notably WebRTC/webrtcbin pipelines) by presenting a TLS certificate with an oversized Subject Distinguished Name. The Subject DN is written into a fixed 2048-byte stack buffer with no bounds checking (CWE-121), and overflowing it corrupts the stack and terminates the process. There is no public exploit identified at time of analysis and it is not listed in CISA KEV; impact is limited to availability (process crash), with no code execution or data exposure claimed.
Heap buffer overflow in GStreamer's rfbsrc (RFB/VNC source) plugin lets a malicious VNC server crash or corrupt the memory of any client that connects to it. When the server advertises a 16bpp framebuffer and sends Hextile-encoded updates, the background-fill path writes 32-bit pixels into a 16-bit buffer, producing an out-of-bounds heap write. No public exploit identified at time of analysis; the primary confirmed impact is denial of service, with potential for further memory corruption. This is a client-side flaw requiring the victim to connect to attacker-controlled infrastructure.
Denial of service in Red Hat / 389 Directory Server (389-ds-base, versions since ~1.3.2/2013) allows an authenticated LDAP client to crash the server by sending an oversized UNBIND packet over a SASL integrity-protected connection. The oversized data overflows a fixed 512-byte heap receive buffer in sasl_io_recv() (sasl_io.c), and in FreeIPA / Red Hat IdM any domain user, enrolled host, or service account with a valid Kerberos ticket can trigger it after GSSAPI authentication. There is no public exploit identified at time of analysis, and this flaw is distinct from the earlier CVE-2025-14905 schema.c overflow, which did not fix this code path.
Privilege escalation to root and Kerberos-based authentication bypass in SSSD's Active Directory GPO provider affects Red Hat Enterprise Linux 6 through 10 and OpenShift Container Platform 4. Because ad_gpo_extract_smb_components() fails to sanitize '..' sequences in the gPCFileSysPath LDAP attribute (CWE-23), an actor holding AD GPO management rights can force an SSSD-enrolled host to write attacker-controlled files outside the GPO cache as root, injecting Kerberos configuration to bypass authentication. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
Local-to-domain-wide root privilege escalation in SSSD's LDAP sudo provider allows an authenticated LDAP directory user with write access to any subtree to inject a malicious sudoRole object and gain root-level sudo on every SSSD-enrolled host. The flaw exists because, when ldap_sudo_search_base is left unset, SSSD searches the entire directory tree for sudoRole objects, trusting rules planted anywhere in the DIT. Rated CVSS 8.8 by Red Hat and reported against RHEL 6 through 10 and OpenShift Container Platform 4; no public exploit identified at time of analysis and it is not listed in CISA KEV.
Heap memory corruption in GIMP's PSD (Photoshop) file parser allows a malicious .psd image to overflow an integer in read_RLE_channel(), producing an undersized heap allocation for the RLE row-length table that is then overwritten row-by-row, potentially yielding denial of service or arbitrary code execution. The flaw affects GIMP as shipped across Red Hat Enterprise Linux 6 through 9 and is triggered when a victim opens or imports a crafted PSD file. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
Stack-based memory corruption in GIMP's PNM image parser lets an attacker execute code or crash the application when a victim opens a malicious PNM/PBM/PGM/PPM file. The flaw is an off-by-one in pnmscanner_gettoken() that writes a null terminator one byte past a stack buffer; it is local and requires the user to open the crafted file (UI:R). No public exploit is identified at time of analysis, and EPSS is low (0.12%), consistent with the CISA SSVC 'Exploitation: none' judgment.
Authenticated denial of service in Red Hat Advanced Cluster Security for Kubernetes (RHACS) 4 allows any user holding a valid API token to exhaust Central's resources. Because Central does not cap the nesting depth of queries served on its authenticated GraphQL API, a single deeply nested query can drive excessive CPU and memory consumption and take down the RHACS management plane. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV, but the low-privilege network vector makes it trivial for any token holder to trigger.
Heap-based buffer overflow in GIMP's Paint Shop Pro (PSP) image format parser lets an attacker achieve arbitrary code execution or crash the application when a victim opens a maliciously crafted PSP file. The flaw stems from incorrect buffer-size arithmetic on low bit-depth images, and affects GIMP as shipped across Red Hat Enterprise Linux 6 through 9. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; exploitation requires local file-open interaction (CVSS 7.3).
Remote code execution and privilege escalation in HPLIP (HP Linux Imaging and Printing) affects the hpcups print filter across Red Hat Enterprise Linux 6 through 10, where an integer overflow triggered by specially crafted print data can corrupt memory. This is an incomplete-fix follow-up to CVE-2026-8631, meaning the original patch did not fully close the flaw, and no public exploit has been identified at time of analysis. The Red Hat CVSS of 9.8 reflects a network-reachable, unauthenticated attack path, though realistic exploitation depends on how the CUPS print pipeline is exposed.
Memory corruption in GIMP's Paint Shop Pro (.psp) import parser lets an attacker crash the application or possibly execute code by persuading a victim to open a crafted PSP image file. The root cause is a double-free (CWE-415) in the read_layer_block() routine; exploitation requires local user interaction to open the file and results in per-user, client-side compromise rather than server-side or unattended exploitation. There is no public exploit identified at time of analysis, the SSVC decision framework rates exploitation as 'none' and automatable as 'no', and EPSS is low at 0.12% (2nd percentile), yet Red Hat tracks the defect across RHEL 6 through 9 and a vendor patch plus an upstream commit are available.
Arbitrary file write in the Feast Feature Server's `/save-document` endpoint lets an unauthenticated remote attacker write attacker-controlled JSON to the host filesystem, bypassing the endpoint's path restrictions to overwrite application configuration or startup scripts. Because no credentials are required (CVSS 9.1, PR:N), any network-reachable attacker can corrupt system integrity, cause denial of service through disk exhaustion, or potentially achieve remote code execution. This flaw also ships in Red Hat OpenShift AI (RHOAI), which bundles Feast; there is no public exploit identified at time of analysis and it is not in CISA KEV.
Privilege escalation in Foreman (the engine behind Red Hat Satellite 6) lets an authenticated user holding usergroup-management permissions attach arbitrary roles - including the administrator role - to a user group and then enroll themselves, gaining full admin-level control. The Usergroup model fails to validate that the assigning user actually holds the roles being granted, breaking the RBAC delegation boundary. Rated CVSS 8.8; no public exploit identified at time of analysis and it is not listed in CISA KEV, but the low attack complexity and clear escalation path make it a strong patch priority.
Denial of service in libarchive's RAR5 reader allows remote attackers to crash applications that decompress untrusted RAR5 archives via a double-free (CWE-415) of the stale filtered_buf pointer. Reported by Red Hat and affecting libarchive as shipped across Red Hat Enterprise Linux 6 through 10, OpenShift Container Platform 4, and Red Hat Hardened Images, the flaw is triggered purely by parsing a malicious archive entry. No public exploit has been identified and the issue is not in CISA KEV; impact is limited to availability (CVSS 7.5, A:H only) with no code execution or data exposure claimed.
Arbitrary VS Code command execution in the Red Hat vscode-java extension allows a malicious Java source file to embed hidden commands inside JavaDoc hover Markdown, so that a developer who simply clicks a crafted link in a hover popup triggers attacker-chosen commands that can escalate to full system compromise in trusted workspaces. The flaw stems from the extension rendering JavaDoc hovers as fully-trusted Markdown, and it also affects Red Hat OpenShift Dev Spaces, which bundles the extension. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the network reach combined with only a single click of user interaction makes it high-impact.
Cross-tenant VM compromise in KubeVirt (and Red Hat OpenShift Virtualization 4) occurs when spec.configuration.migrations.disableTLS is set to true, causing virt-handler to expose an unauthenticated plaintext TCP proxy into a virt-launcher's virtqemud control socket on all interfaces. An authenticated tenant who can run any pod on the cluster network can reach this listener and issue arbitrary libvirt RPC commands against another tenant's virtual machine - reading guest memory, altering VM state via QMP, or destroying the VM. No public exploit identified at time of analysis; not listed in CISA KEV, and no EPSS score was provided.
Server-side request forgery in Red Hat Build of Apicurio Registry 3 allows a Developer-role user to coerce the registry server into issuing HTTP requests to arbitrary internal URLs. The flaw stems from the WSDLReaderAccessor instantiating a wsdl4j WSDLReader with the javax.wsdl.importDocuments feature left enabled, so a crafted WSDL artifact with attacker-controlled import locations is fetched when content validation runs at FULL strictness. There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV; CVSS is 7.4 (scope-changed) and exploitation requires authenticated low-privilege access plus a non-default validation setting.
Server-side request forgery and denial of service in Red Hat Build of Apicurio Registry 3 stem from unsafe XML parsing in the ContentTypeUtil.isParsableXml() method, which builds a SAXParserFactory without secure processing or external-entity restrictions (CWE-611, XXE). An attacker with artifact-write permission - or any unauthenticated client when the registry runs in its default configuration - can upload a crafted XML artifact whose external DTD/entity references force the server to fetch attacker-chosen URLs (blind SSRF into internal networks) or expand nested entities for resource-exhaustion DoS. CVSS is 8.5 (scope-changed, high availability impact); no public exploit identified at time of analysis.
Signature-verification bypass in Keycloak (and Red Hat's Keycloak-based products such as Red Hat Single Sign-On 7 and Red Hat Build of Keycloak 26.6/26.6.4) lets an attacker holding valid client credentials abuse a JWT algorithm-confusion weakness in the JWT Authorization Grant flow to forge client assertions and mint unauthorized access tokens. The forged tokens allow impersonation of any federated user tied to the affected Identity Provider, yielding unauthorized access and potential privilege escalation. There is no public exploit identified at time of analysis and the issue is not on CISA KEV; Red Hat rates it 8.1 (High).
Stored Cross-Site Scripting in Red Hat Build of Keycloak lets an authenticated administrator with `manage-client` permission (or access to client registration endpoints) register a malicious client whose redirect URI uses a case-insensitive `javascript:` or `data:` scheme, bypassing URI validation. When a victim later clicks a crafted link - for example during the logout flow or within the Admin Console - the script executes in the Keycloak origin, enabling session/token theft and effective code execution in that trusted context. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV; it carries a CVSS 7.3 (PR:L, UI:R).
Privilege escalation in Keycloak (Red Hat Build of Keycloak) lets an authenticated delegated admin with management rights over a single low-privilege group hijack the entire realm. A missing authorization check in the Admin REST API's GroupResource.addChild() endpoint allows reparenting an arbitrary group; when Fine-Grained Admin Permissions v2 (FGAPv2) is enabled, an attacker can move a privileged group (e.g., one holding realm-admin) under a group they control, inheriting management and password-reset rights over its members. There is no public exploit identified at time of analysis and the issue is not in CISA KEV, but the resulting full realm takeover makes it a serious escalation primitive in environments that delegate group administration.
Authorization bypass in the Keycloak Policy Enforcer allows any authenticated user to circumvent all enforced access controls - role, scope, and User-Managed Access (UMA) permission checks - by embedding the configured access-denied page path inside a request URL as a path segment or query parameter. The affected component ships in the Red Hat Build of Keycloak, and successful exploitation grants unauthorized access to protected resources. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Session hijacking in the foreman-mcp-server component (shipped with Red Hat Satellite 6) allows local attackers to take over active administrative sessions by reusing leaked session IDs that the server caches without re-validating authentication tokens. Because session IDs are written to standard logs, any user with log read access can replay them to gain administrative control and pivot to infrastructure-wide code execution. No public exploit identified at time of analysis and the issue is not listed in CISA KEV.
Credential disclosure in Red Hat Ansible Automation Platform 2.5 and 2.6 allows any authenticated user to retrieve plaintext OAuth tokens, vault passwords, and SSH keys by sending forged Worker messages to the Event-Driven Ansible websocket endpoint. The /api/eda/ws/ansible-rulebook endpoint fails to verify permissions on activation_id values, enabling lateral credential theft across tenants. No public exploit identified at time of analysis, but the low attack complexity and scope-changed CVSS of 9.6 make this a high-priority patch.
Credential theft in Red Hat OpenShift Container Platform's Windows Machine Config Operator (WMCO) allows adjacent-network attackers to intercept SSH sessions to Windows worker nodes and steal WICD and kubelet bootstrap credentials. WMCO fails to verify the remote SSH host key when configuring Windows nodes, enabling a man-in-the-middle attacker positioned on the cluster network to capture credentials sufficient to assume Windows node identities. No public exploit identified at time of analysis, and the issue is not in CISA KEV.
Privilege escalation in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform allows a compromised Windows worker node holding WICD credentials to obtain a cluster-administrator client certificate. The WICD CSR auto-approver checks for the system:wicd-nodes organization but fails to reject additional organization values such as system:masters, enabling full cluster takeover. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in the cifs-utils cifs.upcall helper allows low-privileged Linux users to gain root by abusing the kernel request_key interface to load a malicious NSS module inside an attacker-controlled mount namespace. The root-owned helper fails to drop privileges before performing user-name resolution, so the attacker's NSS module executes with full root capabilities. No public exploit identified at time of analysis, but the bug affects every supported Red Hat Enterprise Linux release (6 through 10) and OpenShift Container Platform 4, making it a high-priority hardening fix for any host with CIFS/SMB client functionality.
Remote code execution in galaxy_ng's legacy role import API (v1) allows an authenticated user controlling a git repository to execute arbitrary commands on the pulp worker by crafting a branch or tag name containing shell metacharacters. The flaw stems from unsanitized git ref interpolation into a subprocess.run() call with shell=True inside do_git_checkout(), and only affects deployments where GALAXY_ENABLE_LEGACY_ROLES is explicitly enabled (non-default). No public exploit identified at time of analysis.
Heap buffer overflow in GNOME localsearch (formerly tracker-miners) tracker-extract-mp3 component on Red Hat Enterprise Linux 8/9/10, Ubuntu, Debian, and SUSE allows remote attackers to trigger an out-of-bounds heap read by delivering a malformed MP3 file with crafted ID3 performer tags, leading to crashes (DoS) or disclosure of process memory contents. No public exploit identified at time of analysis, and the EPSS score of 0.19% (9th percentile) plus CISA SSVC 'Exploitation: none' indicate low real-world exploitation activity despite the 8.1 CVSS rating. Vendor patches are available across Red Hat (RHSA), Ubuntu USN-8019-1, Debian, and SUSE-SU-2026:0780/21854.
Out-of-bounds read in GStreamer's VMnc decoder allows remote attackers to crash the application or disclose memory contents when a victim opens a maliciously crafted VMnc video file. The flaw stems from a signed integer overflow in payload-size arithmetic that bypasses a length check when cursor dimensions are abnormally large. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Heap buffer overflow in GStreamer's librfb (RFB/VNC client) allows a malicious VNC server to corrupt heap memory on a connecting client, potentially leading to remote code execution or denial of service. The flaw stems from validating rectangle area instead of individual dimensions, letting attacker-controlled rectangles extend beyond the framebuffer. No public exploit identified at time of analysis, though the issue affects GStreamer as shipped across Red Hat Enterprise Linux 6 through 10.
Out-of-bounds read and denial-of-service in GStreamer's RealMedia demuxer (gst-plugins-ugly) allows remote attackers to crash, hang, or potentially leak limited adjacent memory when a victim opens a maliciously crafted RealMedia (.rm) file. The flaw stems from unvalidated offsets in re_skip_pascal_string() and an attacker-controlled loop counter in the FILEINFO metadata parser. No public exploit identified at time of analysis, and the CVE is not on the CISA KEV list.
Out-of-bounds read in the GStreamer RealMedia demuxer (gst-plugins-ugly) allows a maliciously crafted .rm file to crash the consuming application and potentially leak small amounts of adjacent heap memory through stream metadata. The flaw affects Red Hat Enterprise Linux 7, 8, 9, and 10 systems shipping the vulnerable demuxer, and exploitation requires a user to open or otherwise process the file (UI:R). There is no public exploit identified at time of analysis, and the issue is not on the CISA KEV list.
Heap memory corruption in the WavPack audio decoder of GStreamer's gst-plugins-good package allows remote attackers to crash applications or potentially achieve arbitrary code execution when a victim opens a malicious WavPack (.wv) audio file. The flaw, tracked as CVE-2026-53705 and reported by Red Hat, affects Red Hat Enterprise Linux versions 7, 8, 9, and 10, and stems from an integer overflow during buffer size calculation that produces an undersized heap allocation later overrun by decoded samples. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but the multimedia decoder attack surface combined with RCE potential makes it a meaningful patching priority.
Out-of-bounds read in the VA JPEG decoder shipped in GStreamer's gst-plugins-bad allows a remote attacker to crash the decoder or potentially leak adjacent memory contents when a victim opens a maliciously crafted JPEG file. The flaw stems from the JPEG parser trusting a segment-length value from the bitstream without verifying it fits within the buffer, and affects Red Hat Enterprise Linux 6 through 10 where the plugin is consumed. There is no public exploit identified at time of analysis and the issue is not in CISA KEV.
Local privilege escalation via arbitrary root-owned file overwrite affects libreport's ABRT post-create event handler scripts on Red Hat Enterprise Linux 6, 7, and 8. The event scripts write output using shell redirections that lack the O_NOFOLLOW flag, so a local low-privileged user who plants a symlink in a writable crash-dump path can cause the root shell to follow it and clobber any file on the system, which can be leveraged for full system compromise. SSVC rates technical impact as total, but there is no public exploit identified at time of analysis and EPSS is negligible (0.02%, 5th percentile).
Local privilege escalation in the abrt-dbus D-Bus service on Red Hat Enterprise Linux 6, 7, and 8 allows a low-privileged local user to race the ChownProblemDir method against still-running post-create event handlers. By invoking ChownProblemDir while privileged event scripts hold a write lock on the dump directory, the attacker gains filesystem ownership of files being written by root-context handlers, enabling tampering with privileged output and potential privilege escalation. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in the abrt-dbus D-Bus service on Red Hat Enterprise Linux 6, 7, and 8 allows any unprivileged local user to win a TOCTOU race against the SetElement method, writing arbitrary text files into root-owned dump directories. By exploiting the gap between dump directory creation and post-create event execution, an attacker bypasses package validation and persists crash data for unpackaged binaries inside privileged paths, with no public exploit identified at time of analysis.
Heap buffer overflow in 389 Directory Server (389-ds-base) SASL I/O layer allows authenticated remote attackers to crash the LDAP service or achieve remote code execution after a successful SASL bind with integrity protection (SSF > 0). The flaw stems from an integer overflow in sasl_io_start_packet() that bypasses the nsslapd-maxsasliosize ceiling, enabling roughly 2 MB of attacker-controlled heap corruption. No public exploit identified at time of analysis, and the impact is amplified in FreeIPA and Red Hat Identity Management deployments where any enrolled user, host, or service principal qualifies as an authenticated attacker.
Root command injection in dracut's legacy DHCP path allows adjacent-network attackers to execute arbitrary commands inside the initramfs by sending crafted DHCP options (e.g., malicious hostname) that are written unescaped into temporary shell scripts. The flaw affects Red Hat Enterprise Linux 6 through 10, Red Hat Hardened Images, and OpenShift Container Platform 4, granting full system compromise during early boot. No public exploit identified at time of analysis, and EPSS is low (0.16%, 36th percentile), but SSVC rates technical impact as total.
Remote denial of service in 389 Directory Server (Red Hat Directory Server 11/12/13 and Red Hat Enterprise Linux 6 through 10) allows unauthenticated network attackers to crash the LDAP daemon by exploiting an unchecked BER structure allocation in the dereference control plugin when the host is under memory pressure. No public exploit identified at time of analysis, and EPSS exploitation probability is very low (0.09%, 25th percentile), but the unauthenticated network-reachable nature warrants prompt patching of internet-facing or business-critical directory services.
Privilege escalation in Keycloak allows a limited administrator to become a full realm administrator by importing users with realm-admin role mappings via the POST /admin/realms/{realm}/partialImport endpoint, bypassing Fine-Grained Admin Permissions (FGAP). Exploitation requires a high-privilege authenticated user, and while a proof-of-concept exploit exists, the EPSS score is very low (0.03%) and there is no evidence of active exploitation.
Out-of-bounds heap write in X.Org X server and Xwayland DRI2 buffer handling allows a local authenticated client to corrupt server memory by requesting multiple DRI2BufferBackLeft attachments alongside one DRI2BufferFrontLeft. Successful exploitation crashes the display server or, when the X server runs setuid root (a still-common legacy deployment), enables local privilege escalation to root. No public exploit is identified at time of analysis and the issue is not listed in CISA KEV.
Local privilege escalation in the X.Org X server and Xwayland arises from a use-after-free in SyncChangeCounter() that a local authenticated attacker can trigger by orchestrating two client connections - one creating multiple SyncCounters, the other destroying them while they are being changed. On systems where the X server still runs as root (common on legacy Linux setups), successful exploitation yields root code execution; at minimum it crashes the display server. No public exploit identified at time of analysis, but the bug is confirmed by Red Hat and a fix has landed upstream in xserver.
Local privilege escalation in the X.Org X server and Xwayland arises from a use-after-free in FreeCounter() when SyncCounter objects are destroyed across multiple client connections. Authenticated local attackers on affected Red Hat Enterprise Linux 6 through 10 systems can crash the server or escalate to root when the X server runs with elevated privileges. No public exploit identified at time of analysis, and the issue is not listed in CISA KEV.
Local privilege escalation in X.Org X server and Xwayland stems from an incomplete fix for CVE-2025-26597, where CheckKeyTypes() fails to clamp non-canonical key types to XkbMaxShiftLevel, enabling stack-based buffer overflows. Authenticated local users on Red Hat Enterprise Linux 6 through 10 can crash the display server or, when X runs as root, escalate to root privileges. No public exploit identified at time of analysis, though the upstream commit reveals the vulnerable code path and the prior CVE-2025-26597 has known exploitation history.
Stack-based buffer overflow in X.Org X server and Xwayland's _XkbSetMapChecks() function allows local authenticated attackers to crash the server or potentially escalate privileges to root when the X server runs with elevated privileges. The flaw resides in CheckKeyTypes() writing to a fixed mapWidths[256] stack buffer at a client-controlled offset, affecting Red Hat Enterprise Linux versions 6 through 10. No public exploit identified at time of analysis, but an upstream fix has been merged into the xserver repository.
Local privilege escalation in the X.Org X server and Xwayland stems from a stack-based buffer overflow during font alias resolution, where a 256-byte server-side stack buffer is overrun by libXfont2 alias target names of up to 1023 bytes. An authenticated local attacker who can influence font alias files can crash the server or, when the X server runs as root, escalate to root privileges. No public exploit is identified at time of analysis and CVSS is 7.8 (Local/Low complexity/Low privileges).
Local privilege escalation in X.Org X server and Xwayland enables authenticated local users to trigger a use-after-free in miSyncDestroyFence() by racing two client connections against a shared fence object. Successful exploitation can crash the display server or escalate privileges to root when the X server runs as root, which remains common on legacy and embedded Linux deployments. No public exploit identified at time of analysis, but an upstream fix has been committed by the X.Org maintainers.
