Use-after-free in Linux kernel Bluetooth MGMT subsystem allows local authenticated users to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability stems from improper condition checking in mgmt_add_adv_patterns_monitor_complete(), which can leave dangling pointers after freeing memory without unlinking from the list. Patches available across multiple kernel versions (6.12.80, 6.17, 6.18.21, 6.19.11, 7.0). No evidence of active exploitation (not in CISA KEV), low EPSS score (0.02%, 5th percentile) suggests limited attacker interest despite high CVSS severity.
Double-free memory corruption in Linux kernel bcmasp network driver allows local authenticated attackers with low privileges to achieve arbitrary code execution, privilege escalation, or system crash. The vulnerability affects kernel versions 6.6 through early 7.0 release candidates. Vendor patches available across stable branches (6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (5th percentile) indicates very low real-world exploitation probability, and no active exploitation or public POC has been identified. This represents a low-priority issue for most environments despite the 7.8 CVSS score, as it requires local authenticated access and affects only systems using the specific bcmasp Broadcom network driver.
Out-of-bounds memory write in Linux kernel iavf (Intel Adaptive Virtual Function) driver allows local authenticated attackers with low privileges to achieve high confidentiality, integrity, and availability impact via race condition during concurrent ethtool operations. The vulnerability stems from inconsistent use of queue counters (real_num_tx_queues vs num_active_queues vs num_tx_queues) across ethtool statistics functions, enabling memory corruption when changing network channels via 'ethtool -L' while simultaneously querying statistics with 'ethtool -S'. Patches available for kernel versions 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS exploitation probability is low (0.02%, 5th percentile) with no public exploit or active exploitation identified at time of analysis.
Type confusion in Linux kernel team driver allows local authenticated users to trigger memory corruption and potential privilege escalation. The team_setup_by_port() function incorrectly copies header_ops from non-Ethernet lower devices (such as GRE interfaces) without proper context validation, causing callbacks like dev_hard_header() to interpret netdev_priv() as the wrong structure type when processing stacked network topologies (e.g., gre → bond → team). While CVSS rates this 7.8 (High), EPSS probability is very low at 0.02% (5th percentile), and no active exploitation or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0).
Use-after-free in Linux kernel Bluetooth Intel driver enables local privilege escalation to kernel code execution. Affects Linux kernel 4.3 through 7.0-rc5, with patches available in versions 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0. Exploitation requires local authenticated access with low privileges (CVSS PR:L). EPSS score of 0.02% (5th percentile) indicates low probability of widespread exploitation. No public exploit code or active exploitation confirmed at time of analysis, though technical details in CVE description provide implementation roadmap.
Use-after-free in Linux kernel's xe GPU driver allows local authenticated users to execute arbitrary code with kernel privileges. The vulnerability occurs in the SR-IOV physical function migration restore path when error handling fails to nullify a freed data pointer, enabling subsequent write operations to reference deallocated memory. With CVSS 7.8 (High) and very low EPSS (0.02%), this represents typical kernel memory corruption risk requiring local access and low privileges. Vendor patches are available for affected 6.19 and 7.0-rc versions.
Use-after-free in Linux kernel meson-spicc SPI driver allows local authenticated attackers to escalate privileges or crash the system. The vulnerability stems from a double-put reference counting error during driver removal - devm_spi_register_controller() already handles cleanup automatically, but meson_spicc_remove() explicitly calls spi_controller_put() again, releasing the same memory twice. EPSS probability is low (0.02%, 5th percentile), no active exploitation confirmed, and vendor patches are available across multiple kernel versions (6.12.80, 6.18.21, 6.19.11, 7.0). This targets systems using Amlogic Meson SoC SPI controllers, requiring local authenticated access to exploit.
Use-after-free in Linux kernel AMD display driver allows local authenticated users to execute arbitrary code, corrupt memory, or cause denial of service. Affects systems with AMD graphics using Display Stream Compression (DSC) and multi-stream transport (MST), particularly laptops with integrated displays and external DP-MST monitors. The vulnerability arises when mode changes occur simultaneously with DSC reconfigurations, causing improper stream lifecycle management. Vendor patch available across multiple kernel versions (6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% indicates low exploitation probability in the wild, with no CISA KEV listing or public exploit identified at time of analysis.
Local privilege escalation and kernel memory corruption in the Linux kernel's Intel Xe (drm/xe) GPU driver arises from incorrect prev/next tracking in the VM bind ioctl unwind path, affecting kernel 6.8 through 7.0-rc6 and stable branches before the 6.12.80/6.18.21/6.19.11 fixes. When a vectored bind operation fails and unwinds, the driver leaves overlapping GPU virtual-memory areas (VMAs) in place, corrupting VM state and triggering a WARNING at xe_vm.c:1217; a local user with access to the DRM/render device can reach this via crafted xe_vm_bind_ioctl calls (as observed with the vkd3d Direct3D-to-Vulkan translation layer). No public exploit identified at time of analysis, and EPSS is negligible at 0.02%.
Use-after-free in Linux kernel ISO-TP CAN protocol driver allows local authenticated users to read freed memory, corrupt kernel state, or execute arbitrary code with kernel privileges. Affects kernels from commit 96d1c81e to 6.6.131, 6.12.80, 6.18.21, and 6.19.11. Vendor-released patches available across stable kernel branches. EPSS score 0.02% (5th percentile) indicates low probability of mass exploitation, and no public exploit identified at time of analysis, though CVSS 7.8 reflects high local privilege escalation potential if successfully exploited.
Memory corruption in the Linux kernel VFIO PCI subsystem allows local authenticated users to trigger double-free conditions and potentially execute arbitrary code with kernel privileges. The vulnerability stems from an incorrect error-handling path in the dma-buf export feature that calls dma_buf_put() before dma_buf_export() succeeds, leading to unbalanced reference counts and memory corruption during file descriptor exhaustion scenarios. Exploitation probability remains very low (EPSS 0.02%, 5th percentile) with no public exploit code or evidence of active exploitation. Patches are available in stable kernel versions 6.19.11 and 7.0.
Buffer overflow in Linux kernel ext4 filesystem allows local attackers with user interaction to achieve arbitrary code execution via crafted extent tree metadata. The ext4_ext_correct_indexes() function fails to validate index pointer bounds when walking up the extent tree, enabling slab-out-of-bounds memory reads when processing malicious filesystem images. With CVSS 7.8 (high severity) but only 0.02% EPSS (5th percentile), this represents elevated theoretical risk with minimal observed real-world exploitation. Vendor patches available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0), and no public exploit code or active exploitation confirmed at time of analysis.
Use-after-free in Linux kernel RDMA/EFA driver allows local authenticated users with low privileges to execute arbitrary code with high confidentiality, integrity, and availability impact. The vulnerability affects the admin queue completion handling where completion context data is accessed after being freed, creating a window for memory corruption exploitation. Affects kernel versions from 5.12 through 7.0-rc7, with vendor patches available for stable branches 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability, and no public exploit code or CISA KEV listing identified at time of analysis.
Memory corruption in the Linux kernel sma1307 ASoC driver allows local authenticated users to trigger a double-free condition leading to potential privilege escalation, denial of service, or information disclosure. The vulnerability stems from improper cleanup of device-managed memory allocations in error paths within the sma1307_setting_loaded() function, where devm_kzalloc()-allocated resources are incorrectly freed with kfree(), causing devres to later release the same memory a second time. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability, and no active exploitation or public POC has been identified.
Use-after-free in Linux kernel XFRM IPTFS subsystem allows local authenticated attackers to trigger high-severity memory corruption through failed state cloning operations. The vulnerability stems from premature publication of mode_data pointer before allocation completion, enabling arbitrary code execution, privilege escalation, or denial of service when IPsec IP-TFS (IP Traffic Flow Security) mode cloning fails. Vendor patches available for kernel versions 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (4th percentile) indicates very low observed exploitation probability despite CVSS 7.8 rating, likely due to the specific IPTFS configuration prerequisite and local access requirement.
Use-after-free in Linux kernel idxd DMA engine driver allows local authenticated attackers to execute arbitrary code, disclose sensitive memory, or crash the system when Function Level Reset operations fail to allocate scratch memory. The vulnerability affects Linux kernels from commit 98d187a98903 through versions 6.14, 6.18.x before 6.18.21, and 6.19.x before 6.19.11. Vendor patches are available across stable branches with EPSS indicating 0.02% exploitation probability (4th percentile), suggesting limited active targeting despite the high CVSS 7.8 score. No CISA KEV listing or public exploit code identified at time of analysis.
Privilege escalation to root in uutils coreutils chroot utility allows low-privileged local attackers with write access to the chroot target directory to execute arbitrary code via malicious NSS module injection. The vulnerability triggers when --userspec option causes getpwnam() to load attacker-controlled shared libraries from the new root before dropping privileges, enabling container escape or full system compromise on glibc-based systems. CVSS 7.8 with Scope Changed indicates host compromise from containerized environments. SSVC framework confirms POC availability and total technical impact, though exploitation requires specific configuration (writable NEWROOT) and is not automatable.
Heap buffer overflow in GNU Binutils XCOFF linker allows arbitrary code execution when a local user processes a malicious object file. Red Hat Enterprise Linux versions 6 through 10 are confirmed affected via CPE data. CVSS 7.8 reflects local attack vector requiring user interaction (opening/linking the crafted file). No active exploitation confirmed (not in CISA KEV), and no public proof-of-concept identified at time of analysis. Real-world risk depends heavily on whether development workflows involve linking untrusted XCOFF files, which is uncommon outside AIX/PowerPC cross-compilation scenarios.
Insecure direct object reference in Fullstep V5 allows authenticated users to enumerate and modify other users' supplier registration data via predictable API endpoints. Authenticated attackers with low privileges can exploit vulnerable GET and POST endpoints to list sensitive user information (/api/suppliers/v1/suppliers/) and update arbitrary user profiles including personal details and documents (/#/supplier-registration/supplier-registration/). CVSS 7.6 reflects high confidentiality and integrity impact with low attack complexity. No public exploit code identified at time of analysis, but the IDOR pattern is trivial to exploit once authenticated. INCIBE-CERT advisory confirms patch availability from vendor.
Remote code execution in Red Hat Apache Camel Infinispan component allows low-privileged attackers to execute arbitrary code via unsafe deserialization in ProtoStream remote aggregation repository. Exploiting this vulnerability requires network access and low-privilege credentials but grants full system compromise affecting confidentiality, integrity, and availability. The attack complexity is rated high (AC:H), suggesting specific configuration or timing requirements. No active exploitation confirmed at time of analysis (not in CISA KEV), and public exploit code status is unknown.
Identity spoofing in IBM WebSphere Application Server Liberty 17.0.0.3 through 26.0.0.4 allows authenticated attackers with low privileges to impersonate other users and escalate privileges when applications are deployed without proper authentication and authorization controls. The vulnerability requires high attack complexity and low-privilege credentials, but enables complete compromise of confidentiality, integrity, and availability within the application scope. CVSS 7.5 (High) reflects the significant impact once exploitation conditions are met. No public exploit identified at time of analysis, and vendor patch is available per IBM advisory.
Path matching bypass in Spring Security 7.0.0-7.0.4 allows unauthenticated remote attackers to evade authentication, authorization, and other security controls when applications use securityMatchers(String) with a PathPatternRequestMatcher.Builder bean to prepend servlet paths. Improper matcher configuration causes filter chains to silently fail, leaving protected endpoints exposed without intended security controls. No active exploitation confirmed, but CVSS 7.5 with network attack vector (AV:N/AC:L/PR:N) indicates readily exploitable if applications use the specific configuration pattern. VMware-reported vulnerability requires immediate patching for affected Spring Security 7.x deployments.
Remote unauthenticated denial of service crashes Nimiq blockchain nodes by exploiting a protocol state machine flaw. Attackers can force panic conditions in the libp2p discovery handler by opening duplicate protocol substreams, immediately taking peer-to-peer networking offline until manual restart. Vendor-released patch available in version 1.3.0 with no workarounds for unpatched systems, creating urgent upgrade requirement for blockchain node operators.
Denial of service in nimiq-primitives (Nimiq blockchain core library) allows remote unauthenticated attackers to crash nodes via malformed peer-to-peer messages. Attackers announce election macro blocks containing invalid compressed BLS voting keys, triggering an unwrap() panic during header hash validation. Affects all versions prior to 1.3.0. CVSS 7.5 (High) with network attack vector and no complexity. No public exploit identified at time of analysis, but attack is trivial to execute given the network-accessible attack surface and lack of authentication requirements.
Unauthenticated remote attackers can crash free5GC Policy Control Function (PCF) versions before 1.4.3 via repeated HTTP requests to the OAM endpoint over the Service-Based Interface. Each request leaks memory by registering duplicate CORS middleware in the Gin router handler chain, causing progressive memory exhaustion that prevents all User Equipment from establishing 5G sessions. Patched in version 1.4.3 via commit 599803b. EPSS data unavailable; not listed in CISA KEV. CVSS 7.5 High severity reflects network-accessible unauthenticated attack with high availability impact.
Uncontrolled resource consumption in Progress Telerik UI for AJAX RadAsyncUpload component allows remote unauthenticated attackers to exhaust disk space by uploading files exceeding configured size limits through chunked upload bypass. The vulnerability arises from missing cumulative size validation during chunk reassembly, enabling attackers to circumvent intended upload restrictions. No authentication required (CVSS:3.1/AV:N/AC:L/PR:N/UI:N), making this exploitable against any internet-facing application using affected versions. Patch available in version 2026.1.421. No CISA KEV listing or public exploit code identified at time of analysis, but low attack complexity and no authentication barrier indicate straightforward exploitation potential.
Authorization bypass in Spring Security 7.0.0-7.0.4 allows unauthenticated remote attackers to circumvent access controls when applications use servlet-path-based intercept-url configurations. The framework fails to include the servlet path when computing pattern matches for authorization rules, causing protected endpoints to become accessible without proper authorization checks. No public exploit code identified at time of analysis, but the straightforward bypass condition (misconfigured servlet-path directives) and network attack vector (CVSS AV:N/AC:L/PR:N) make this readily exploitable in affected deployments.
Memory exhaustion and kernel crash in Linux kernel's ksmbd SMB server allows remote unauthenticated denial of service via crafted lock requests. The smb2_lock() function contains three critical error-handling defects: memory leaks when vfs_lock_file() returns unexpected errors, stale error propagation in UNLOCK operations, and NULL pointer dereference during rollback when smb_flock_init() allocation fails. CVSS vector indicates network-accessible, low-complexity exploitation requiring no authentication. EPSS score of 0.02% (7th percentile) suggests minimal observed scanning activity, and no KEV listing confirms no widespread exploitation detected. However, the network attack vector (AV:N) and high availability impact (A:H) make this a realistic DoS risk for systems running ksmbd. Vendor patches available across stable kernel series 5.15-6.19.
Deadlock in Linux kernel EROFS filesystem bio completion path enables remote denial of service. When EROFS decompress operations occur in process context (e.g., dm-verity scenarios), vm_map_ram() called with GFP_KERNEL can trigger memory swapping I/O under low memory conditions, causing submit_bio_wait() to deadlock when bio_list is already initialized. CVSS rates this 7.5 High with network attack vector requiring no authentication, yet EPSS scores only 0.02% (7th percentile), suggesting theoretical rather than observed exploitation. Patches available across multiple stable kernel branches (5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). Not listed in CISA KEV and no public exploit identified at time of analysis.
Remote denial of service in dnsdist allows unauthenticated attackers to crash the DNS load balancer by sending specially crafted DNSCrypt queries that trigger a divide-by-zero error. The vulnerability requires no authentication, low attack complexity, and directly impacts service availability for all DNS traffic routed through affected dnsdist instances. Organizations using DNSCrypt protocol support in dnsdist face immediate risk of service disruption from remote attackers.
Cross-site scripting (XSS) in GitLab CE/EE 18.11 before 18.11.1 allows authenticated users to inject unauthorized content into other users' browsers through improper input validation in the Mermaid diagram sandbox. An attacker must have valid GitLab credentials and the victim must view a malicious diagram, limiting real-world impact despite the publicly available exploit code. SSVC analysis rates this as non-automatable with partial technical impact, consistent with the low CVSS 3.5 score.
Remote attackers can corrupt PowerDNS Authoritative Server configuration via specially crafted DNS NOTIFY requests, causing persistent denial of service requiring manual administrator intervention. The attack adds malformed secondary domains to the bind backend, rendering the configuration invalid and preventing the server from restarting. No active exploitation confirmed at time of analysis, but the network-accessible attack vector and lack of authentication requirements elevate risk for internet-facing authoritative DNS servers.
Code injection in Microsoft Kiota versions prior to 1.31.1 allows attackers who control or tamper with OpenAPI descriptions to inject malicious code into generated HTTP client libraries. Exploitation requires developers to generate clients from untrusted or compromised OpenAPI specifications, then compile and execute the poisoned code. The attack chain culminates in arbitrary code execution within the context of applications using the tainted generated clients. CVSS 7.3 with local attack vector and user interaction required suggests lower immediate urgency, though EPSS data is unavailable. No public exploit code or active exploitation confirmed at time of analysis.
Server-Side Request Forgery in Squidex versions prior to 7.23.0 allows authenticated users with asset upload permissions to force the CMS server to fetch arbitrary URLs, including internal network resources and localhost endpoints, storing the retrieved content as platform assets. This enables reconnaissance of internal infrastructure, exfiltration of cloud metadata endpoints (AWS/Azure credentials), and access to services not exposed to the internet. CVSS 7.3 (High) with CVSS 4.0 E:P (Proof-of-concept exists). Vendor patch available in version 7.23.0 per GitHub security advisory GHSA-x7cq-4f4c-8qcv.
Server-Side Request Forgery (SSRF) in Squidex versions before 7.23.0 allows authenticated users with schema editing permissions to force the server to make arbitrary HTTP requests to internal services and cloud metadata endpoints through the Jint scripting engine. The vulnerability can expose cloud provider credentials (e.g., AWS IMDS) and enable lateral movement within internal networks. Exploitation requires only low-privilege authentication (PR:L) and has publicly available exploit code (E:P in CVSS 4.0 vector). Vendor-confirmed patch available in version 7.23.0.
Apache HttpClient 5.6 skips mutual authentication verification in SCRAM-SHA-256 handshakes, allowing network attackers to impersonate legitimate servers without credentials. Affected clients accept unauthenticated server responses, enabling man-in-the-middle attacks that compromise confidentiality and integrity of authenticated sessions. Apache released patched version 5.6.1 addressing the missing authentication check. EPSS score of 0.03% suggests low current exploitation activity, though the network-accessible attack surface (AV:N/AC:L/PR:N) and availability of detailed vendor advisory increase exploitation risk once attackers adapt tooling for SCRAM protocol manipulation.
Recursive chmod operations can bypass --preserve-root protection in uutils coreutils versions prior to 0.6.0, allowing local authenticated users to execute destructive permission changes across the entire root filesystem. The vulnerability stems from incomplete path canonicalization that permits path traversal variants (/../) and symbolic links to circumvent safety checks, potentially causing system-wide denial of service. EPSS score of 0.01% indicates minimal exploitation probability in the wild, with no public exploit code identified and vendor patch available in version 0.6.0.
Arbitrary file write in HTTP Headers plugin for WordPress versions ≤1.19.2 enables authenticated administrators to achieve remote code execution by manipulating htpasswd file path configuration and injecting PHP code via unsanitized username input. Administrators can set a malicious file path (e.g., webroot/shell.php) through 'hh_htpasswd_path' option and inject executable code via the 'hh_www_authenticate_user' field, which is written directly to disk without validation. Wordfence disclosure includes direct source code references showing the vulnerable apache_auth_credentials() and update_auth_credentials() functions. No public exploit code or active exploitation confirmed at time of analysis.
Memory corruption in rust-openssl's key derivation functions allows heap or stack buffer overflow when applications pass undersized buffers to Deriver::derive or PkeyCtxRef::derive on OpenSSL 1.1.x. The vulnerability affects X25519, X448, DH, and HKDF-extract operations where OpenSSL ignores the caller-specified buffer length and unconditionally writes the full shared secret, causing safe Rust code to trigger memory corruption. Vendor patch available in v0.10.78; OpenSSL 3.x deployments are not affected as newer providers correctly validate buffer lengths.
Out-of-bounds memory write in rust-openssl's AES key unwrap function allows attackers who control buffer sizes to corrupt memory via safe API misuse. The aes::unwrap_key() function contains an inverted bounds assertion that accepts undersized output buffers and rejects correctly sized ones, causing the function to write beyond allocated memory by in_.len() - 8 - out.len() bytes. Vendor patch available via GitHub PR #2604 and commit 718d07ff, released in openssl-v0.10.78. No evidence of active exploitation (not in CISA KEV) or public proof-of-concept at time of analysis, but the logic flaw is clearly documented in vendor advisory GHSA-8c75-8mhr-p7r9.
Server-Side Request Forgery in Squidex's backup restoration endpoint allows authenticated administrators to probe internal network services and access cloud metadata endpoints. The RestoreController.PostRestoreJob endpoint accepts arbitrary URLs without SSRF protection, enabling internal reconnaissance through the application's HTTP client. Exploitation requires high privileges (admin authentication) but grants access to confidential internal resources and sensitive cloud service metadata. Version 7.23.0 patches this vulnerability. EPSS exploitation probability and active exploitation status are not reported in available intelligence.
Missing authorization in a+HRD API allows authenticated low-privilege remote attackers to read arbitrary database contents. The vulnerability exists in a specific API method that fails to properly verify user permissions, enabling lateral privilege escalation to access sensitive data beyond the attacker's authorization scope. The CVSS 4.0 score of 7.1 reflects high confidentiality impact with network attack vector and low attack complexity, though exploitation requires valid user credentials.
SQL injection in aEnrich a+HRD allows authenticated remote attackers to read database contents through malicious SQL command injection. The vulnerability requires low-privilege authentication but enables complete confidentiality breach of database information. No active exploitation confirmed via CISA KEV, and EPSS data not available, but the low attack complexity (AC:L) and network attack vector (AV:N) make this exploitable by any authenticated user with basic SQL injection knowledge.
Out-of-bounds read in the Linux kernel io_uring fdinfo handler allows a local, low-privileged user to leak adjacent kernel memory (and potentially crash the kernel) by reading /proc fdinfo for an io_uring instance created with IORING_SETUP_SQE_MIXED. The flaw affects Linux 6.19 and the 7.0 release candidates (rc1-rc7) and is fixed in 6.19.11 and 7.0. EPSS is negligible (0.02%, 5th percentile), there is no public exploit identified at time of analysis, and it is not on the CISA KEV list.
A buffer validation flaw in Linux kernel's TDX guest driver (versions 6.7+) allows local authenticated attackers to leak kernel memory beyond allocated quote buffers into userspace, potentially crossing container isolation boundaries in multi-tenant TDX environments. The vulnerability stems from insufficient validation of host-controlled quote_buf->out_len values during remote attestation operations. Patches available for stable branches 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. EPSS score of 0.02% (5th percentile) indicates low exploitation probability in the wild, with no public exploit code or active exploitation confirmed at time of analysis.
Improper locking in the Linux kernel's PMBus hardware monitoring core (drivers/hwmon/pmbus) allows a local low-privileged attacker to trigger a race condition against unserialized regulator voltage operations, corrupting shared PMBus register state and per-page data. The pmbus_regulator_get_voltage(), set_voltage(), and list_voltage() paths accessed shared data without holding update_lock, and the fix reworks notification delivery through a worker to avoid a mutex deadlock. There is no public exploit identified at time of analysis and EPSS is very low (0.02%), consistent with a hardware-dependent local integrity/availability issue rather than a broadly exploitable flaw.
Path traversal in InstructLab's chat session handler enables local authenticated attackers to write files to arbitrary filesystem locations by manipulating the logs_dir parameter. Red Hat Enterprise Linux AI 3 deployments are confirmed affected. CVSS 7.1 (High) reflects significant confidentiality and integrity impact, though exploitation requires local access and low-level privileges. No active exploitation (CISA KEV) or public proof-of-concept identified at time of analysis. EPSS data not available, suggesting limited immediate widespread exploitation risk despite high severity rating.
Local privilege escalation in uutils coreutils mkfifo allows authenticated users to downgrade permissions on arbitrary files to world-readable mode. When mkfifo attempts to create a FIFO at a path where a file already exists, it erroneously continues execution and calls set_permissions on the existing file, changing its mode to default (typically 644 after umask). This can expose sensitive files like SSH private keys (~/.ssh/id_rsa) or application secrets to unauthorized local users. CISA SSVC confirms proof-of-concept code exists with total technical impact, though EPSS data is not available and the vulnerability is not yet in CISA KEV, indicating exploitation remains theoretical rather than widespread.
OpenRemote Manager allows privilege escalation to Keycloak master realm administrator through improper authorization in the Manager API. Users with write:admin permission in any non-master realm can manipulate realm role assignments in other realms, including master, by exploiting missing authorization checks in the updateUserRealmRoles endpoint. An attacker controlling any user in the master realm can grant themselves admin privileges, achieving full Keycloak administrator access. Vendor-released patch version 1.22.1 addresses this vulnerability. No public exploit code identified at time of analysis, though a detailed proof-of-concept is documented in the advisory.
Privilege escalation in uutils coreutils mkfifo utility allows local attackers with low privileges to manipulate file permissions on arbitrary system files. A TOCTOU race condition between FIFO creation and permission setting enables symlink swapping attacks, redirecting chmod operations to unintended targets. SSVC framework indicates proof-of-concept exists with total technical impact. While CVSS rates this 7.0 (High), exploitation requires high attack complexity (race condition timing), low privileges, and write access to the parent directory where mkfifo is executed - most impactful when the utility runs with elevated privileges in automated scripts or system processes. No active exploitation confirmed (not in CISA KEV); EPSS data not available.
