Information Disclosure

Use-after-free in Linux kernel q6apm audio driver allows local authenticated attackers with low privileges to achieve arbitrary code execution, denial of service, or information disclosure with high impact to confidentiality, integrity, and availability. The flaw affects Qualcomm ASoC q6apm component registration code used in devices like Lenovo 21N2ZC5PUS laptops. Vendor-released patches are available across multiple kernel version branches (6.12.83, 6.18.24, 6.19.14, 7.0.1). EPSS score of 0.02% (5th percentile) indicates low probability of mass exploitation despite high CVSS 7.8, with no confirmed active exploitation or public POC identified at time of analysis.

Use-after-free in Linux kernel MediaTek video encoder allows local authenticated users to corrupt memory and potentially execute arbitrary code. The flaw affects the vcodec driver's encoder release path where ctx memory is freed before canceling scheduled workqueue tasks, enabling race conditions between cleanup and worker threads that may dereference freed memory. KASAN-confirmed exploitation requires local access with low privileges (CVSS AV:L/PR:L). Patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% (5th percentile) indicates very low probability of automated exploitation, with no public exploit identified at time of analysis.

Local privilege-relevant memory corruption in the Linux kernel's powerz hwmon driver (ChargerLAB POWER-Z USB power monitor) allows a local user to trigger a use-after-free by racing a sysfs read against USB device disconnect, dereferencing a freed URB pointer. The bug affects kernels prior to the stable fixes (7.0.1, 6.19.14, 6.18.24, 6.12.83) and carries CVSS 7.8, but with EPSS at just 0.02% (5th percentile) and no public exploit identified at time of analysis, real-world exploitation risk is low. It is not listed in CISA KEV.

Local privilege escalation via a use-after-free in the Linux kernel's ALSA driver for the TerraTec DMX 6Fire USB audio interface (sound/usb/6fire) lets a local attacker corrupt freed slab memory when the device is disconnected. The flaw is a CVSS 7.8 (CVSS:3.1 AV:L/PR:L) memory-corruption bug with publicly available proof-of-concept code, though EPSS is negligible (0.02%) and it is not on CISA KEV. usb6fire_chip_abort() writes chip->card = NULL after snd_card_free_when_closed() may have already freed the card-owned chip struct, giving an attacker a window to hijack freed kernel memory.

Use-after-free and double-free in the Linux kernel's as102 DVB-T USB media driver (drivers/media/usb/as102) allows a local user to corrupt kernel memory by racing an open() of the device node against an error path in as102_usb_probe(). Because the probe error path frees the as102_dev_t structure immediately after usb_register_dev()/usb_deregister_dev() while a userspace file descriptor may still hold a reference, the later .release() path re-accesses and re-frees that structure. CVSS is 7.8 (local, low-privilege); EPSS is negligible (0.02%), no public exploit is identified, and it is not in CISA KEV.

Local privilege escalation and kernel memory corruption in the Linux kernel's HackRF Software-Defined Radio media (V4L2) driver arises from a use-after-free and double-free in the hackrf_probe() error path. When probe fails after v4l2_device_register() has already exposed the device node, the driver frees the hackrf_dev structure directly with kfree() while an already-open file descriptor still holds a reference, so subsequent ioctl() or close() calls dereference and re-free freed memory. There is no public exploit identified at time of analysis; EPSS is 0.02% (5th percentile) and it is not listed in CISA KEV.

Out-of-bounds heap write in Linux kernel CAN gateway CRC8 checksum processing allows adjacent network attackers to corrupt kernel memory and potentially achieve code execution. The cgw_csum_crc8_rel() function in the CAN gateway subsystem uses raw negative index values instead of bounds-checked variables when accessing canfd_frame data, enabling writes up to 56 bytes before the heap object. Exploitation requires CAP_NET_ADMIN capability to configure CAN gateway CRC8 checksums. EPSS exploitation probability is very low (0.02%, 7th percentile) and no active exploitation has been reported. Vendor patches available across multiple kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0).

Out-of-bounds memory access in Linux Kernel's KVM subsystem for LoongArch architecture allows local authenticated attackers with low privileges to read limited kernel memory and cause system crashes. The vulnerability stems from improper handling of empty EIOINTC coremap values in eiointc_update_sw_coremap(), resulting in invalid array indexing into kvm_arch::phyid_map::phys_map[]. While CVSS rates this 7.3 HIGH, the EPSS score of 0.02% (4th percentile) indicates minimal real-world exploitation activity. No active exploitation (not in CISA KEV) or public POC has been identified. Vendor patches are available across multiple stable kernel branches (6.18.21, 6.19.11, 7.0, and mainline).

Denial of service in the Linux kernel's s390 (IBM Z) secure-execution memory subsystem allows storage donated to the Ultravisor to trigger unresolvable secure-storage-access exception loops. Because donated pages lack the PG_arch_1 bit, the prior fixup path (arch_make_folio_accessible()) returned immediately without exporting the page, causing the fault to repeat indefinitely. No public exploit identified at time of analysis; EPSS is negligible (0.02%, 4th percentile) and exploitation is confined to s390 Protected Virtualization guests.

Use-after-free in Linux kernel AMD GPU driver allows local authenticated users to potentially execute arbitrary code, escalate privileges, or cause denial of service. The amdgpu_amdkfd_submit_ib() function in the AMD KFD (Kernel Fusion Driver) prematurely releases a DMA fence reference before waiting on it, creating a race condition where the fence memory may be freed before use. Vendor-released patches are available for multiple stable kernel branches (6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS exploitation probability is very low at 0.02% (7th percentile), and no public exploit or active exploitation has been identified at time of analysis.

Memory management flaw in Linux kernel's Cadence macb network driver causes kernel warning and potential denial of service. Specifically affects the macb Ethernet driver on ARM64 ZynqMP platforms (kernel versions 6.1+ containing commit 6bc8a5098bf4). The vulnerability stems from calling napi_consume_skb() with IRQs disabled during TX packet cleanup, violating kernel API contracts and potentially causing system instability under network load. EPSS exploitation probability is very low (0.02%, 7th percentile) with vendor-released patches available across all stable kernel branches (6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). No active exploitation or public exploit code identified at time of analysis.

Out-of-bounds array access in Linux kernel KVM subsystem on LoongArch allows local authenticated attackers with low privileges to execute arbitrary code, escalate privileges, or cause denial of service by passing negative cpuid values to kvm_get_vcpu_by_cpuid(). The function lacks bounds checking before indexing phyid_map::phys_map[], enabling read/write beyond array boundaries with container escape potential (CVSS scope change). Vendor patches available across multiple stable kernel branches (6.12.80, 6.18.21, 6.19.11). EPSS score of 0.02% indicates low automated exploitation likelihood, with no confirmed active exploitation or public POC at time of analysis.

A workqueue deadlock in Linux kernel NVMe-over-Fabrics target (nvmet) allows remote denial of service via recursive locking during controller disconnect. The nvmet subsystem's async event handler can trigger reentrant workqueue completion when nvmet_ctrl_free() flushes work on the same queue (nvmet-wq) that invoked it, causing a lockdep-detected recursive lock scenario. EPSS score of 0.02% indicates very low probability of exploitation in the wild. Patches available for kernel versions 6.12.80, 6.18.21, 6.19.11, and mainline 7.0 via upstream commits.

Use-after-free in Linux kernel futex subsystem allows local authenticated attackers to achieve code execution, privilege escalation, or denial of service via sys_futex_requeue() with mismatched flags. Discovered through automated LLM analysis by Nicholas, this affects kernel versions 6.7 through 6.19.x, with patches available in 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% (5th percentile) indicates low observed exploitation probability, and no active exploitation or public POC has been identified. The vulnerability requires local access with low-privilege authenticated user credentials (PR:L), making it a post-compromise escalation vector rather than a remote entry point.

Address calculation error in Linux kernel KVM on ARM64 allows local authenticated attackers with low privileges to corrupt memory descriptors, potentially enabling container escape or privilege escalation to compromise host integrity and confidentiality. The vulnerability affects KVM's stage-1/stage-2 page table descriptor swapping logic where pointer arithmetic incorrectly multiplies the offset by 8, causing writes to unintended memory locations. Vendor patches available for Linux 6.19.11 and mainline with EPSS exploitation probability at 5th percentile, indicating low observed exploitation despite high CVSS severity.

Use-after-free in Linux kernel tracing subsystem allows local authenticated attackers to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability occurs when deleting tracing instances with copy_trace_marker enabled, where improper RCU synchronization leaves freed memory accessible. Exploitation requires local access with low privileges to manipulate kernel tracing facilities. EPSS score of 0.02% (4th percentile) indicates low observed exploitation probability. Vendor patches available across multiple stable kernel versions (6.18.20, 6.19.10, 7.0).

Race condition in Linux kernel SMB Direct receive credit management allows remote denial of service against SMB3 network storage services. The flaw enables remote unauthenticated attackers to exhaust receive buffer credits through timing exploitation of the gap between hardware packet reception and completion processing, causing service disruption. EPSS exploitation probability is low (0.02%, 4th percentile), and patches are available from kernel.org for versions 6.18.x, 6.19.x, and 7.0. This affects only systems using SMB Direct (RDMA-enabled SMB3), not standard SMB implementations.

Denial of service in Linux kernel SMB server (ksmbd) affects versions 6.18 through 7.0-rc via race condition in SMBDirect receive credit management. Remote unauthenticated attackers can trigger resource exhaustion through crafted SMB packets exploiting the window between hardware reception and completion processing. Vendor patches released for stable branches 6.18.11, 6.19.1, and mainline 7.0. Low EPSS score (0.02%) indicates limited exploitation interest despite network attack vector and no authentication requirement.

Use-after-free in Linux kernel SMB server (ksmbd) RDMA handling allows remote unauthenticated attackers to execute arbitrary code, escalate privileges, or crash the system via crafted SMB Direct connections. The vulnerability arises when batched RDMA send operations without IB_SEND_SIGNALED flags are prematurely freed during connection failures, causing memory corruption. Vendor patches are available for kernel versions 6.18.11, 6.19.1, and 7.0. EPSS score of 0.02% suggests low observed exploitation probability, and no active exploitation or public POC is confirmed at time of analysis, though the critical CVSS score (9.8) reflects severe potential impact if the SMB Direct feature is enabled.

Privilege escalation in Azure IoT Central enables authenticated attackers to gain unauthorized access to sensitive information and elevate their permissions across tenant boundaries. An attacker with low-privilege credentials can exploit exposed sensitive data over the network to compromise confidentiality, integrity, and availability of other tenant resources. Microsoft has published security guidance, but no independent confirmation of patch availability exists at time of analysis.

Heap over-read in Open Virtual Network (OVN) DHCPv6 client ID processing allows remote unauthenticated attackers to extract sensitive memory contents across network boundaries. The vulnerability affects OVN's DHCPv6 implementation and carries a CVSS score of 8.6 with scope change, enabling cross-tenant information disclosure in multi-tenant virtualized environments. Public advisory released via oss-security mailing list on 2026-04-20, though no confirmed active exploitation or public POC identified at time of analysis.

Remote code execution in Delta Electronics AS320T industrial automation server allows unauthenticated network attackers to trigger memory corruption via malformed GET/PUT requests to the web service. The incorrect buffer size calculation (CWE-131) enables stack-based overflow attacks against network-exposed management interfaces. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N) indicating trivial exploitation conditions and CRITICAL severity, this vulnerability represents an immediate risk to industrial control systems deploying this Delta OT product, though no public exploit or active exploitation confirmed at time of analysis.

Kyverno's apiCall feature automatically attaches the admission controller's ServiceAccount token to HTTP requests without validating the destination URL, enabling authenticated attackers to exfiltrate tokens to attacker-controlled servers and achieve full cluster compromise through webhook configuration tampering. Affects Kyverno versions prior to 1.18.0-rc1, 1.17.2-rc1, and 1.16.4. Vendor-released patches available across all three affected version branches. EPSS data not provided, but the vulnerability enables privilege escalation from low-privilege Kubernetes user to cluster admin via token theft, representing critical risk in multi-tenant environments.

Out-of-bounds read and write in OP-TEE OS PKCS#11 Trusted Application (versions 3.13.0-4.10.0) allows authenticated local attackers with low privileges to read up to 7 bytes beyond heap boundaries and write arbitrary attribute values outside allocated buffers, potentially compromising the integrity and confidentiality of the Trusted Execution Environment. The vulnerability affects Arm TrustZone-based TEE implementations running alongside Linux kernels on Cortex-A cores. Patches available in three upstream commits targeting version 4.11.0. EPSS data not provided; no CISA KEV status indicating targeted rather than widespread exploitation. CVSS 8.7 reflects high confidentiality/integrity impact with scope change, representing potential TEE compromise from the normal world.

Authentication bypass in SenseLive X3050 web management interface allows remote unauthenticated attackers to gain administrative access using default or previously-set credentials. After factory restore via SenseLive Config 2.0 tool, password updates fail to propagate correctly - the interface falsely reports success while the backend continues accepting old credentials. CISA ICS-CERT has issued an advisory (ICSA-26-111-12), indicating this affects industrial control system deployments. With CVSS 9.3 (AV:N/AC:L/PR:N) and CWE-522 (Insufficiently Protected Credentials), this represents critical risk for remotely accessible devices where administrators believe credentials have been changed but remain exploitable.

Information disclosure in FlowiseAI Flowise before 3.1.0 exposes plaintext credentials through the unauthenticated GET /api/v1/public-chatflows/:id and public-chatbotConfig endpoints, which return the full raw flowData for any chatflow flagged public. Because the sanitizeFlowDataForPublicEndpoint helper is absent from the released v3.0.13 Docker image, remote attackers can retrieve credential IDs, plaintext API keys, and password-type fields without authentication. No public exploit is identified at time of analysis and EPSS probability is low (0.04%), but the disclosure is trivially automatable per CISA SSVC.

Broken access control in SpiceJet's Online Booking System exposes complete passenger records through the public booking-retrieval page, which requires only a PNR code and passenger last name with no authentication or ownership verification. Any unauthenticated internet user who obtains or guesses these two inputs can retrieve extensive personal, travel, and booking metadata. No public exploit has been identified at time of analysis and EPSS is low (0.06%), but CISA's SSVC framework rates the flaw as automatable, meaning enumeration at scale is technically feasible.

Sign-up restriction bypass in Mastodon (self-hosted ActivityPub social server) before v4.5.9, v4.4.16, and v4.3.22 allows remote attackers to register accounts on instances that restrict registration by e-mail domain. Because Mastodon validates addresses but does not restrict characters that downstream mail servers interpret differently, a crafted address can pass the allow/deny-list check while ultimately delivering mail to a domain the operator intended to block. No public exploit identified at time of analysis, and EPSS is very low (0.04%), but SSVC rates the flaw automatable with partial technical impact.

Unauthenticated sensitive data disclosure in FlowiseAI Flowise before 3.1.0 lets any remote party retrieve stored secrets by requesting /api/v1/public-chatbotConfig/:id with only a chatflow UUID. The endpoint returns the full flowData object - including plaintext password-type fields (e.g. Unstructured API keys), HTTP Authorization headers from Requests nodes, and internal endpoint/webhook URLs - with no authorization check, enabling credential theft and downstream pivoting. Publicly available exploit code exists (vendor GHSA advisory with PoC), though EPSS is very low (0.05%, 15th percentile) and it is not on CISA KEV.

Sandbox escape in Google Chrome on Windows before 147.0.7727.117 lets a remote attacker exploit a race condition (CWE-362) in the GPU process by luring a victim into loading a crafted video file, potentially breaking out of the browser sandbox. Google rates the Chromium severity Medium, but the CVSS scope-changing vector drives an 8.3 score; there is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.06%, 19th percentile).

Sandbox escape in Google Chrome's GPU process on Android (versions prior to 147.0.7727.117) can be triggered by an attacker who has already compromised the renderer process, using a crafted HTML page to force an out-of-bounds read (CWE-125) that leaks GPU-process memory and potentially breaks out of the renderer sandbox. Rated High by Chromium and CVSS 9.6, it is a second-stage bug requiring prior renderer compromise. No public exploit identified at time of analysis, and EPSS is low at 0.07% (21st percentile).

Use-after-free in the Linux kernel's kernel TLS (net/tls) data path lets a local attacker corrupt kernel memory by racing the -EBUSY crypto-backlog error path of tls_do_encryption(). When crypto_aead_encrypt() returns -EBUSY, both the async tls_encrypt_done() callback and the synchronous error path clean up encrypt_pending and the scatterlist, double-decrementing a sentinel so a later sendmsg frees an in-flight tls_rec while a cryptd callback is still pending. Despite an NVD CVSS of 9.8, EPSS is 0.01% and there is no public exploit identified at time of analysis, reflecting the narrow race conditions required.

Out-of-bounds memory read in the X.Org X server's XKB key types request handling allows a local, authenticated client to disclose adjacent server memory or crash the server (DoS), with higher-impact outcomes possible in certain configurations. The flaw affects the X server component shipped across Red Hat Enterprise Linux 6 through 10 and corresponding SUSE releases, and stems from missing bounds validation on an XKB request. There is no public exploit identified at time of analysis, EPSS is negligible (0.01%), and CISA/SSVC records no known exploitation.

Denial of service in the CODESYS EtherNet/IP adapter stack (versions 1.0.0.0 up to but not including 4.9.0.0) lets an unauthenticated remote attacker exhaust all available TCP connections, blocking legitimate EtherNet/IP clients from establishing new sessions. The flaw is remotely reachable with no authentication or user interaction (CVSS 4.0 8.7, VA:H). No public exploit has been identified at time of analysis and EPSS is low (0.14%), but CISA SSVC rates it automatable with partial technical impact.

Use-after-free in Linux kernel CAN raw socket implementation allows local authenticated attackers to corrupt memory and potentially achieve code execution. The vulnerability stems from premature deallocation of percpu uniq storage in raw_release() while raw_rcv() may still access it via deferred RCU callbacks. Patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS exploitation probability remains low (0.02%, 5th percentile) with no active exploitation confirmed at time of analysis.

Information disclosure in Google BigQuery materialized view refresh allows authenticated users to extract sensitive data via crafted views that generate error messages containing confidential information. Google Cloud Platform patched this server-side vulnerability on 29 January 2026 with automatic remediation requiring no customer action. The CVSS 4.0 score of 7.1 reflects high confidentiality impact with network-accessible attack vector and low attack complexity, though no public exploit or CISA KEV listing exists at time of analysis.

PRNG state reuse across forked processes in CryptX for Perl allows remote attackers to recover private signing keys through cryptographic nonce-reuse attacks. When Crypt::PK objects are created before fork() in preforking web servers like Starman, every child process inherits identical PRNG state, causing duplicate randomness in cryptographic operations. Two ECDSA or DSA signatures generated by different worker processes are sufficient to mathematically recover the private key. EPSS exploitation probability is low (0.02%), but CISA SSVC framework confirms proof-of-concept availability and automatable exploitation. Vendor patch released in CryptX 0.088.

DLL hijacking in LiveOn Meet Client and Canon Network Camera Plugin installers allows local attackers to execute arbitrary code with installer privileges when users run vulnerable installer executables from directories containing malicious DLLs. The flaw affects four installer executables (Downloader5Installer.exe, Downloader5InstallerForAdmin.exe, CanonNWCamPlugin.exe, CanonNWCamPluginForAdmin.exe) version 1.0.0.0. No public exploit identified at time of analysis, though the attack technique is well-documented. CVSS 8.4 (High) reflects significant impact contingent on user interaction and attacker's ability to place malicious files in the installer directory before execution - real-world risk depends heavily on organizational download practices and endpoint controls preventing untrusted DLL placement.

Mass deletion of content, assets, and user accounts in Statamic CMS versions prior to 5.73.20 and 6.13.0 occurs via query parameter manipulation on Control Panel endpoints (requiring minimal authentication like 'view entries' permission) or unauthenticated exploitation through REST/GraphQL APIs if explicitly enabled without authentication. Authenticated attackers with low-privilege viewer roles can escalate to delete resources they should only read. Unauthenticated attackers can exploit misconfigured API endpoints (non-default configuration) to achieve the same destructive impact. CVSS 8.1 (High) reflects network-accessible attack with low complexity, though exploitation conditions vary significantly by deployment configuration. No active exploitation confirmed (not in CISA KEV), EPSS data not provided.

XML node injection in the @xmldom/xmldom npm package allows remote attackers to inject arbitrary XML elements via maliciously crafted comment content containing the sequence '-->' which prematurely terminates comments during serialization. Applications processing untrusted input through createComment() or manipulating comment node data can emit structurally altered XML that downstream consumers parse as attacker-controlled elements. Public exploit code exists (GitHub PR #987). CVSS:4.0 rates this 8.7 (High) with network vector, low complexity, and no privileges required. Vendor-released patches require opt-in protection flag { requireWellFormed: true } to maintain backward compatibility with W3C spec defaults; existing code remains vulnerable unless explicitly migrated.

Path traversal in EspoCRM admin template management allows authenticated administrators to read, create, overwrite, or delete arbitrary files on the server filesystem. The vulnerability affects all versions prior to 9.3.4 and stems from unsanitized `name` and `scope` parameters in template path construction. Publicly available exploit code exists (GitHub security advisory GHSA-44c3-xjfp-3jrh), though no CISA KEV listing or confirmed active exploitation. CVSS 7.2 reflects high impact across confidentiality, integrity, and availability, but exploitation requires high-privilege (admin) access, significantly limiting real-world exposure to insider threats or compromised admin credentials.

Server-side request forgery in monetr's Lunch Flow integration allows authenticated users on self-hosted instances to force the server to issue HTTP GET requests to arbitrary URLs, with response bodies from failed requests reflected in API error messages. This enables information disclosure attacks against internal networks, cloud metadata endpoints (AWS EC2 instance metadata without IMDSv2), and RFC1918 private addresses. The vulnerability is compounded by unbounded response buffering that creates a denial-of-service vector via memory exhaustion. Patch available in v1.12.5. The hosted my.monetr.app service is not affected as Lunch Flow is disabled there. Self-hosted instances with default configuration (Lunch Flow enabled, public signup allowed) are at highest risk.

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.

Integer truncation in Nimiq core-rs-albatross's skip block proof verification allows authenticated validators to forge consensus quorum with insufficient signatures. Prior to v1.3.0, attackers exploit usize-to-u16 casting during BitSet iteration by inserting indices spaced at 65536 intervals - these inflate the quorum count via len() but collapse onto identical u16 slots during BLS signature aggregation, enabling a single malicious validator to masquerade as 2f+1 signers and pass verification. CVSS 9.6 (Critical) reflects network vector with low complexity and changed scope impacting integrity and availability of the Proof-of-Stake consensus. No EPSS or KEV data available; vendor-released patch confirmed in v1.3.0 via GitHub advisory and commit d020590.

Xerte Online Toolkits versions 3.15 and earlier expose the server-side filesystem root path through an unauthenticated GET request to the /setup page, allowing remote attackers to retrieve sensitive path information rendered in HTML responses. This information disclosure enables exploitation of path-dependent vulnerabilities such as relative path traversal in connector.php, potentially leading to unauthorized file access or further system compromise.

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.

Cross-site scripting (XSS) in GitLab CE/EE versions 18.10.0-18.10.3 and 18.11.0 enables unauthenticated attackers to execute arbitrary JavaScript in victim browser sessions via improper path validation. GitLab disclosed this vulnerability with publicly available exploit code (HackerOne report 3572231), though CISA SSVC indicates no active exploitation confirmed at time of analysis. CVSS 8.0 reflects the changed scope (S:C) allowing impact beyond the vulnerable component, though High attack complexity (AC:H) and required user interaction (UI:R) limit ease of exploitation. Patched in versions 18.10.4 and 18.11.1.

Out-of-bounds memory access in Linux kernel perf subsystem allows local authenticated attackers with low privileges to achieve high confidentiality, integrity, and availability impact. The vulnerability occurs when group_sched_in() fails during performance monitoring event handling and event inheritance uses the wrong PMU (Performance Monitoring Unit) context, leading to improper rollback and memory corruption. Despite high CVSS score (7.8), EPSS probability indicates very low real-world exploitation likelihood (0.02%, 5th percentile). Vendor patches available across multiple stable kernel branches (6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0) per git.kernel.org commit references.

Use-after-free in Linux Kernel platform driver core allows local authenticated attackers to achieve high-severity impacts including code execution, privilege escalation, or denial of service. The vulnerability stems from unsafe access to the driver_override field during device probing when the bus match() callback executes without device lock protection. Patches are available across multiple kernel branches (6.12.80, 6.18.21, 6.19.11, 7.0) per vendor commits. EPSS score of 0.02% (5th percentile) indicates low observed exploitation probability, and no CISA KEV listing exists, suggesting this remains a theoretical risk rather than actively exploited threat despite the high CVSS 7.8 score.

Use-after-free in Linux kernel XFRM subsystem allows local authenticated attackers to achieve arbitrary code execution with high privileges. The vulnerability arises when XFRM policy hash threshold work items (policy_hthresh.work) outlive network namespace teardown, dereferencing freed struct net memory in xfrm_hash_rebuild(). Vendor patches available across multiple stable kernel versions (6.12.80, 6.18.21, 6.19.11, 7.0) confirm the issue affects kernels since commit 880a6fab8f6b. EPSS score of 0.02% (5th percentile) indicates low observed exploitation probability despite CVSS:3.1 score of 7.8; no CISA KEV listing or public POC identified at time of analysis.

Buffer over-read in Linux kernel Bluetooth L2CAP allows adjacent network attackers to disclose sensitive kernel memory and crash systems via malformed Enhanced Credit Based Connection Requests. Affects multiple stable kernel versions (6.12.x, 6.18.x, 6.19.x). Vendor patches available for all affected branches. EPSS score of 0.02% indicates low observed exploitation probability despite the network-adjacent attack vector and lack of required authentication. No public exploit identified at time of analysis.

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.

Use-after-free in Linux kernel Open vSwitch module causes system crash when deleting network interfaces on PREEMPT_RT kernels. The vulnerability is confirmed patched in multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0) with upstream fixes available via kernel.org commits. EPSS score of 0.02% (7th percentile) indicates very low exploitation likelihood. No active exploitation confirmed (not in CISA KEV). Local authenticated access required (CVSS AV:L/PR:L) with high impact (CVSS 7.8), but exploitation depends on PREEMPT_RT kernel configuration and specific Open vSwitch teardown race conditions.

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.

Use-after-free in Linux kernel packet socket handling allows local attackers with low privileges to achieve kernel memory corruption, potentially leading to privilege escalation, information disclosure, or denial of service. The vulnerability stems from a race condition in packet_release() where NETDEV_UP events can re-register a socket into a fanout group's array after cleanup begins but before the socket number is zeroed, leaving dangling pointers. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score is low (0.02%, 7th percentile) and no active exploitation is confirmed (not in CISA KEV), suggesting limited real-world exploitation despite high CVSS 7.8 rating.

Use-after-free in Linux kernel ICSSG PRU Ethernet driver allows remote code execution with CVSS 9.8 scoring. Affects TI ICSSG network driver in kernels 6.15 through 7.0 (patched in 6.19.11 and 7.0). The flaw causes CPPI descriptors to be freed before timestamp processing completes on every received packet, creating a exploitable memory corruption condition. Despite critical CVSS scoring, EPSS probability is very low (0.02%, 5th percentile) and no active exploitation or public POC has been identified. The network attack vector (AV:N) combined with zero-day timing suggests this may be scored for worst-case remote exploitation scenario, but actual exploitability via network packets requires deeper investigation of ICSSG hardware context and packet processing pipeline.

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 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.

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.

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.

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.

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%.

Information disclosure and memory corruption in the Linux kernel's in-kernel SMB3 server (ksmbd) arises from smb2_calc_max_out_buf_len() being called with a hardcoded header length instead of the true offsetof() of the response ->Buffer field, after the read-compound rework in commit e2b76ab8b5c9. On affected kernels running ksmbd (6.6 through 7.0-rc3, plus stable backports), a miscalculated maximum output buffer length can cause the server to over-read into the response IOV, leaking adjacent kernel memory to an SMB client or corrupting response buffers. No public exploit identified at time of analysis, and EPSS is very low (0.03%, 9th percentile), consistent with a niche, non-default kernel subsystem rather than mass exploitation.

Remote unauthenticated denial-of-service in Linux kernel's ksmbd SMB server allows attackers to terminate arbitrary active user sessions by sending crafted multichannel binding requests with invalid credentials. The flaw affects ksmbd (kernel-mode SMB server) across multiple stable kernel branches (6.1.x through 7.0). Vendor patches available for all affected versions. EPSS score of 0.08% (23rd percentile) indicates low observed exploitation likelihood, with no CISA KEV listing or public POC identified at time of analysis. The CVSS 8.2 rating reflects network-accessible attack surface with high availability impact, though actual exploitation requires specific SMB multichannel configuration.

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 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.

Use-after-free in Linux kernel media subsystem allows local authenticated attackers to potentially execute arbitrary code, escalate privileges, or cause system crashes. The race condition between MEDIA_REQUEST_IOC_REINIT and VIDIOC_REQBUFS(0) affects request-capable V4L2 media devices in kernels since version 4.20. Patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and 7.0). EPSS score of 0.02% indicates very low likelihood of mass exploitation, 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 virtio_net driver allows local authenticated attackers with low privileges to potentially achieve high confidentiality, integrity, and availability impact. The flaw triggers when virtio_net is configured with napi_tx=N (non-NAPI transmit mode) and the IFF_XMIT_DST_RELEASE flag is cleared by tc route filter rules. When a network namespace is destroyed while packets remain queued in the virtio transmit ring, the freed dst_ops structure is later dereferenced during packet cleanup, causing kernel memory corruption. Vendor patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (7th percentile) suggests low probability of mass exploitation, and no active exploitation or public POC has been identified at time of analysis.

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.

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.

Out-of-bounds memory access in Linux kernel's IBM Virtual Fibre Channel (ibmvfc) driver allows adjacent network attackers to leak kernel memory contents. A compromised or malicious VIO server can supply a crafted num_written value exceeding max_targets in discover targets MAD responses, causing unbounded indexing into disc_buf[] and embedding out-of-bounds kernel data in subsequent PLOGI and Implicit Logout MADs sent back to the attacker. Vendor patches available across all maintained kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% (7th percentile) indicates low observed exploitation probability. No public exploit code or CISA KEV listing identified at time of analysis.

Use-after-free vulnerability in Linux kernel iomap subsystem allows memory corruption when filesystem block size differs from I/O granularity. The flaw occurs during buffered read operations when ctx->cur_folio is accessed after ownership transfers to the I/O helper, potentially leading to data corruption, information disclosure, or system crashes. Affects Linux kernel 6.19.x series. CVSS 9.8 critical severity, but EPSS exploitation probability is very low (0.02%, 5th percentile). Vendor patches available via mainline kernel commits. No active exploitation or public POC identified at time of analysis.

Use-after-free in Linux Kernel XFS filesystem allows local authenticated users to execute arbitrary code, escalate privileges, or cause system crashes during filesystem unmount operations. The vulnerability stems from a race condition where background reclaim and inodegc processes continue running while the Active Item List (AIL) is being flushed during unmount, enabling concurrent access to freed memory structures. Patches are available across multiple stable kernel versions (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, 7.0). EPSS score of 0.02% suggests very low probability of mass exploitation, and no active exploitation or public POC is identified at time of analysis.

Use-after-free in Linux Kernel XFS file system allows local authenticated users to execute arbitrary code, escalate privileges, or cause denial of service. The vulnerability affects XFS implementations from kernel 5.9 onward due to improper handling of Active Item List (AIL) pointers when performing buffer I/O in inode and quota push callbacks. With EPSS exploitation probability at 0.02% and no confirmed active exploitation, this represents a moderate real-world risk limited by local access requirements and low attack complexity. Patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 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.

Linux kernel ext4 filesystem allows mounting of maliciously crafted filesystems with bigalloc and non-zero s_first_data_block, potentially triggering memory corruption or information disclosure. Affects all Linux kernel versions from 2.6.12 (commit 1da177e) through 7.0, with patches released in stable branches 5.10.253, 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, and 6.19.11. CVSS 7.8 indicates high severity with local access and user interaction required. EPSS score of 0.02% (7th percentile) suggests low probability of widespread exploitation, and no active exploitation confirmed (not in CISA KEV).

Use-after-free in Linux kernel ext4 filesystem allows local attackers to potentially execute arbitrary code or cause denial of service during unmount operations. The vulnerability stems from a race condition between ext4_put_super() teardown and update_super_work() error notification, where sysfs_notify() accesses a freed kernfs_node object after kobject_del() has released it. Fixed in stable kernel releases 5.15.203, 6.1.168, 6.6.131, 6.12.80, 6.18.21, 6.19.11, and mainline 7.0. EPSS score of 0.02% (7th percentile) suggests low probability of exploitation in the wild, though CVSS vector indicates straightforward local exploitation requiring user interaction.

Use-after-free and NULL pointer dereference vulnerabilities in Linux kernel's ksmbd SMB server allow remote unauthenticated attackers to achieve arbitrary code execution, information disclosure, or denial of service. The flaws occur during oplock (opportunistic lock) publication when error handling frees memory still referenced by concurrent readers, and when global lease lists are accessed before critical pointers are initialized. With CVSS 9.8 (AV:N/AC:L/PR:N/UI:N), this represents a critical remote attack surface, though EPSS score of 0.02% (5th percentile) suggests minimal observed exploitation activity. Vendor patches are available across affected kernel versions 6.6.130-6.19.9.

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.

Read retry logic in the Linux kernel's netfs subsystem can incorrectly abandon all remaining subrequests due to an uninitialized or invalid pointer, potentially exposing unintended memory contents or causing denial of service through kernel crashes. Affects Linux kernel 6.12 through early 6.19 and 7.0 development branches. Vendor patches available for 6.18.21, 6.19.11, and mainline 7.0. EPSS score of 0.02% (4th percentile) indicates low real-world exploitation probability. Not listed in CISA KEV. CVSS 8.8 reflects network attack vector with user interaction required.

Privilege escalation in Augmentt 1.0 allows authenticated low-privilege users to manipulate HTTP parameters and gain super administrator access, exposing all tenant data and configurations to unauthorized modification. CVSS 9.6 critical severity with scope change indicates cross-tenant impact potential. Public proof-of-concept code exists on GitHub (PENGUINSECQ repository). SSVC framework rates this as proof-of-concept exploitation with partial technical impact, not automatable due to authentication requirement.

Memory corruption in Linux kernel's algif_aead cryptographic interface allows local authenticated users to achieve arbitrary kernel memory read/write, leading to privilege escalation to root. The vulnerability stems from improper handling of in-place operations introduced in commit 72548b093ee3, affecting kernel versions from 4.14 through 6.19.x. Multiple public exploit codes exist including proof-of-concept demonstrations from security researchers, with EPSS score of 0.01% indicating currently low widespread exploitation likelihood despite POC availability.

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.

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.

Authentication bypass via user impersonation affects Spring Security 7.0.0 through 7.0.4, where the SubjectX500PrincipalExtractor mishandles malformed CN values in X.509 client certificates and extracts the wrong username. Authenticated attackers presenting a carefully crafted certificate can be authenticated as a different (potentially higher-privileged) user. No public exploit identified at time of analysis; EPSS is very low (0.02%) and CISA SSVC marks exploitation as none.

Local privilege escalation in FreeBSD 13.5 through 15.0 allows unprivileged processes to gain root privileges by exploiting a use-after-free condition in the TIOCNOTTY ioctl implementation. When a process detaches from its controlling terminal and exits, a dangling pointer in the terminal structure references freed session memory, which attackers can manipulate to escalate privileges. This vulnerability affects multiple stable and release branches with CVSS 8.4 (High) but low EPSS probability (0.02%, 5th percentile), indicating theoretical severity without observed widespread exploitation. Not listed in CISA KEV, suggesting no confirmed active exploitation at time of analysis.

Session fixation in pyLoad 0.5.0b3.dev97 and earlier allows authenticated users to retain revoked administrative privileges until logout. After an administrator demotes a user's role or revokes permissions, the affected user's active session continues to operate with the old cached privileges, enabling unauthorized administrative actions. Publicly available exploit code exists via GitHub commit e95804fb0d06cbb07d2ba380fc494d9ff89b68c1. With CVSS 8.8 (High) but requiring low-privilege authentication (PR:L), this represents an elevation-of-privilege vector in multi-user pyLoad deployments where role changes are expected to take immediate effect.
