Use-after-free in Foxit PDF Reader and Foxit PDF Editor allows local attackers to execute arbitrary code or crash the application via specially crafted PDF documents. When scripts modify document structures, the software fails to maintain valid object references during page information queries, enabling pointer dereference of freed memory. Successful exploitation requires user interaction to open a malicious PDF file, achieving high confidentiality, integrity, and availability impact with CVSS 7.8. No active exploitation or public exploit code identified at time of analysis, though CVSS vector indicates low attack complexity once victim interaction occurs.
Kernel memory corruption in Linux's MPTCP subsystem allows a use-after-free in __inet_lookup_established affecting IPv6 subflow sockets. Because mptcp_subflow_init() copied tcpv6_prot before inet6_init() had registered its slab cache, MPTCP IPv6 child sockets were allocated from kmalloc-4k without the SLAB_TYPESAFE_BY_RCU guarantee, so lockless RCU ehash lookups could dereference freed socket memory. There is no public exploit identified at time of analysis, and the EPSS score is very low (0.03%), but the flaw is remotely reachable via network traffic on hosts using MPTCP over IPv6.
Local privilege escalation and memory corruption in the Linux kernel's netfilter nf_tables conntrack (nft_ct) subsystem allows a local user with network-admin capability to trigger a use-after-free by destroying a conntrack timeout object while packets on other CPUs still reference it. The flaw stems from nft_ct_timeout_obj_destroy() calling kfree() immediately after nf_ct_untimeout() without waiting for an RCU grace period, leaving a dangling RCU-protected pointer read during nf_conntrack_tcp_packet(). No public exploit identified at time of analysis, and EPSS is very low (0.02%, 7th percentile), but a KASAN reproducer ('exploit' task) is described in the commit and the bug is a classic exploitable CWE-416 heap UAF.
Memory leak (with latent use-after-free risk) in the Linux kernel's DAMON monitoring subsystem (mm/damon/stat) allows a local, privileged user to leak damon_ctx objects and potentially trigger use-after-free by repeatedly toggling the DAMON_STAT 'enabled' control after a damon_call() failure. Affected are kernels on the 6.17-6.19 line prior to the stable fixes; the flaw is classified CWE-416 (Use After Free). There is no public exploit identified at time of analysis, and EPSS is negligible (0.02%, 4th percentile).
Local privilege-escalation potential via a use-after-free in the Linux kernel's vub300 MMC host-controller driver (drivers/mmc/host/vub300.c), affecting kernels built with CONFIG_MMC_VUB300 through 6.17 and stable branches prior to 6.18.23/6.19.13. Because the controller structure was allocated with device-managed (devm) memory while the driver keeps its own explicit reference count, the last reference can outlive driver unbind, letting the kernel dereference freed memory on disconnect or probe deferral. No public exploit identified at time of analysis, and EPSS is negligible (0.02%), consistent with the requirement that the uncommon vub300 USB-to-SDIO hardware be physically present.
Use-after-free in Linux kernel's lan966x network driver allows local authenticated attackers to achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The flaw occurs in lan966x_fdma_reload() when RX buffer allocation fails - freed pages remain referenced by active DMA descriptors, causing hardware to write into memory now controlled by other kernel subsystems. Vendor patches available for stable branches 6.12.82, 6.18.23, 6.19.13, and mainline 7.0. EPSS score of 0.02% (5th percentile) indicates low probability of widespread exploitation. No CISA KEV listing or public exploit identified at time of analysis, but successful exploitation grants kernel-level privileges to local attackers.
Use-after-free in Linux kernel OCFS2 filesystem enables local attackers with low privileges to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability occurs when filemap_fault() drops mmap_lock before returning VM_FAULT_RETRY, allowing concurrent munmap() to free the vm_area_struct while ocfs2_fault() still holds a dangling pointer. Vendor patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS exploitation probability is very low (0.02%, 5th percentile) with no public exploit identified at time of analysis.
Use-after-free in Linux kernel memory management allows remote code execution when the folio_unmap_invalidate() function incorrectly accesses freed mapping structures. Kernel versions between 1da177e4c3f4 and patches 6.19.14/7.0.1 are affected. Exploitation probability is low (EPSS 2%, percentile 5%), with no confirmed active exploitation or public POC at time of analysis. Despite the critical CVSS 9.8 score indicating network-based unauthenticated attack, the description suggests this is a kernel memory corruption bug requiring local kernel code paths to trigger, not direct remote network exploitation - CVSS vector conflicts with technical nature and should be validated against vendor guidance.
Use-after-free in Linux kernel KVM x86 MMIO emulation allows local authenticated users with low privileges to potentially execute arbitrary code, escalate privileges, or cause denial of service. The flaw occurs when KVM's emulator initiates MMIO writes using on-stack variables that cross page boundaries between two MMIO pages, creating dangling pointers when fragments are processed across separate KVM_RUN calls, especially when different tasks handle subsequent runs. EPSS exploitation probability is very low (0.02%, 5th percentile), and vendor patches are available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. No active exploitation or public POC identified at time of analysis.
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 blk-cgroup subsystem allows local authenticated users to potentially execute arbitrary code, escalate privileges, or crash the system. The vulnerability occurs in cgwb_release_workfn() when releasing cgroup writeback structures, where a CSS reference is dropped before subsequent dereference, creating a race condition. Meta reports sporadic crashes in production across multiple kernel versions. Patches available for stable branches 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% suggests low widespread exploitation probability, and no 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 escalation and denial of service in the Linux kernel's em28xx USB media driver arises from a use-after-free (CWE-416) in em28xx_v4l2_open(), which reads dev->v4l2 without holding dev->lock. A local attacker who can open the V4L2 device node during a race with the driver's init error path or teardown can trigger a use-after-free on the embedded video_device (via v4l2_fh_init accessing vdev->ctrl_handler) or a NULL dereference in em28xx_resolution_set(). No public exploit identified at time of analysis, and EPSS is very low (0.02%), consistent with a hard-to-win kernel race requiring physical/local USB device presence.
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.
Local privilege escalation and denial of service in the Linux kernel's bcache subsystem stems from a use-after-free of the cached_dev.sb_bio structure; if a cached backing device is stopped while a superblock write is in flight, the freed bio is dereferenced at I/O completion (endio), corrupting kernel memory. Affected systems are those running bcache-backed block devices (observed crashing via librbd/libceph rbd workloads), where a local user with the ability to trigger device teardown during superblock activity can crash the host or potentially corrupt kernel memory. This carries no public exploit identified at time of analysis and an EPSS of just 0.02%, consistent with a hard-to-time race rather than a readily weaponized flaw.
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.
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.
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.
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).
Sandbox escape in Google Chrome's DevTools component (versions prior to 147.0.7727.117) lets an attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page. Rated High by Chromium and CVSS 9.6, this is a use-after-free (CWE-416) that serves as the second link in a multi-stage exploit chain rather than a standalone remote code execution. No public exploit identified at time of analysis, EPSS is very low (0.03%), and CISA SSVC records no observed exploitation, so it is a patch-and-move-on desktop browser fix rather than an emergency.
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.
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.
Use-after-free in Linux kernel CXL (Compute Express Link) subsystem allows local authenticated attackers to corrupt memory and potentially execute arbitrary code or cause kernel panics. The flaw occurs in cxl_detach_ep() during device removal when parent port references are freed prematurely, before child operations complete. Affects Linux kernel 6.3 through 7.0-rc5; patched in versions 6.12.80, 6.18.21, 6.19.11, and 7.0. EPSS score of 0.02% indicates low exploitation probability. No active exploitation or public exploit code identified at time of analysis.
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 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 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 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.
Use-after-free in Linux kernel SPI subsystem (fsl_lpspi driver) causes NULL pointer dereference when DMA channels are torn down while SPI transfers are active. Local attackers with low privileges can trigger denial of service or potentially execute arbitrary code on affected systems running Linux kernel versions from 4.10 through 7.0-rc2, particularly impacting embedded and IoT devices using Freescale LPSPI controllers. EPSS score of 0.02% indicates very low observed exploitation probability, and no public exploit code or active exploitation has been identified at time of analysis. Vendor-released patches available across all affected 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).
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 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.
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).
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.
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.
Use-after-free memory corruption (CWE-416) in Mozilla Firefox 149 and ESR 115.34/140.9, plus the shared Gecko engine in Thunderbird 149 and Thunderbird ESR 140.9, can lead to arbitrary code execution within the browser process when a victim renders attacker-controlled web content. This is a rolled-up batch of memory-safety bugs reported by Mozilla's own developers; Mozilla states some showed evidence of memory corruption presumed exploitable for code execution. There is no public exploit identified at time of analysis, the bug is not in CISA KEV, and EPSS is very low (0.06%, 17th percentile), consistent with the CVSS 7.5 rating being held down by high attack complexity (AC:H) and required user interaction (UI:R).
Memory corruption in Firefox's Widget: Cocoa component on macOS enables remote denial of service through use-after-free exploitation. Mozilla patched this in Firefox 150 and Firefox ESR 140.10 after internal discovery. The CVSS vector indicates network-accessible exploitation requiring no authentication or user interaction, though SSVC assessment classifies technical impact as partial and exploitation as non-automatable. No public exploit identified at time of analysis, with SSVC indicating no evidence of active exploitation.
Use-after-free in Firefox's WebAssembly JavaScript engine enables remote denial-of-service attacks against users running unpatched versions below Firefox 150. The vulnerability allows network-based attackers to crash the browser without authentication or user interaction by triggering memory corruption in WebAssembly processing. Mozilla patched this in Firefox 150 (MFSA2026-30). EPSS data not available, not listed in CISA KEV, and SSVC framework rates exploitation as 'none' with non-automatable, partial technical impact-suggesting lower real-world risk despite CVSS 7.5 severity.
Remote attackers can crash Mozilla Firefox by triggering a use-after-free in the JavaScript Engine, exploiting freed memory during JS execution to cause denial of service. Affects all unpatched Firefox versions below 150, ESR 115.35, and ESR 140.10. CVSS 7.5 (High) reflects network-accessible exploitation with no authentication required, though SSVC assessment indicates non-automatable exploitation with partial technical impact. No public exploit code or active exploitation (KEV) confirmed at time of analysis, and ENISA tracking suggests European-focused monitoring.
High-severity denial-of-service in Firefox WebRTC component allows remote unauthenticated attackers to crash the browser via network-based use-after-free memory corruption. Affects Firefox versions prior to 150 and Firefox ESR prior to 140.10. Vendor-released patches available (Firefox 150, Firefox ESR 140.10). CVSS 7.5 reflects high availability impact with low attack complexity and no privileges required. No public exploit identified at time of analysis, though SSVC framework classifies technical impact as partial and exploitation as none, suggesting limited real-world activity despite the theoretical ease of exploitation indicated by CVSS.
High-severity denial-of-service condition in Mozilla Firefox DOM processing allows remote attackers to crash the browser via network-delivered content without authentication or user interaction. Fixed in Firefox 150, Firefox ESR 115.35, and Firefox ESR 140.10. CVSS 7.5 reflects network attack vector with low complexity (AV:N/AC:L/PR:N/UI:N) but impact limited to availability (A:H). EPSS data not provided. Not listed in CISA KEV, indicating no confirmed active exploitation. SSVC framework rates exploitation as 'none' and technical impact as 'partial', suggesting lower real-world priority despite high CVSS score.
Remote code execution in Google Chrome on Android versions prior to 147.0.7727.101 is possible through a use-after-free vulnerability in the Payments feature. Attackers who successfully convince users to perform specific UI interactions on a malicious webpage can achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The vulnerability requires high attack complexity and user interaction (CVSS:3.1/AV:N/AC:H/PR:N/UI:R), indicating social engineering is necessary. Google has released Chrome 147.0.7727.101 to address this issue. No evidence of active exploitation (not in CISA KEV) or public proof-of-concept code has been identified at time of analysis.
Arbitrary code execution within Chrome's sandbox affects all versions prior to 147.0.7727.101 via crafted HTML pages exploiting a use-after-free in codec processing. Remote attackers require user interaction (visiting a malicious page) but need no authentication. CVSS 8.8 (High) with network attack vector, low complexity, and high impact across confidentiality, integrity, and availability. Google patched this in the stable channel update released April 15, 2026. No public exploit code or CISA KEV listing identified at time of analysis, though Chromium issue tracker #495996858 indicates vendor-confirmed vulnerability.

Low-complexity attack requires only low-privileged local access to achieve full system compromise (SYSTEM-level privileges). Microsoft has released patches for all affected versions. No public exploit identified at time of analysis, but the low attack complexity (AC:L) and requirement for only low privileges
Use-after-free in Foxit PDF Reader and Foxit PDF Editor allows local attackers to execute arbitrary code or crash the application via specially crafted PDF documents. When scripts modify document structures, the software fails to maintain valid object references during page information queries, enabling pointer dereference of freed memory. Successful exploitation requires user interaction to open a malicious PDF file, achieving high confidentiality, integrity, and availability impact with CVSS 7.8. No active exploitation or public exploit code identified at time of analysis, though CVSS vector indicates low attack complexity once victim interaction occurs.
Kernel memory corruption in Linux's MPTCP subsystem allows a use-after-free in __inet_lookup_established affecting IPv6 subflow sockets. Because mptcp_subflow_init() copied tcpv6_prot before inet6_init() had registered its slab cache, MPTCP IPv6 child sockets were allocated from kmalloc-4k without the SLAB_TYPESAFE_BY_RCU guarantee, so lockless RCU ehash lookups could dereference freed socket memory. There is no public exploit identified at time of analysis, and the EPSS score is very low (0.03%), but the flaw is remotely reachable via network traffic on hosts using MPTCP over IPv6.
Local privilege escalation and memory corruption in the Linux kernel's netfilter nf_tables conntrack (nft_ct) subsystem allows a local user with network-admin capability to trigger a use-after-free by destroying a conntrack timeout object while packets on other CPUs still reference it. The flaw stems from nft_ct_timeout_obj_destroy() calling kfree() immediately after nf_ct_untimeout() without waiting for an RCU grace period, leaving a dangling RCU-protected pointer read during nf_conntrack_tcp_packet(). No public exploit identified at time of analysis, and EPSS is very low (0.02%, 7th percentile), but a KASAN reproducer ('exploit' task) is described in the commit and the bug is a classic exploitable CWE-416 heap UAF.
Memory leak (with latent use-after-free risk) in the Linux kernel's DAMON monitoring subsystem (mm/damon/stat) allows a local, privileged user to leak damon_ctx objects and potentially trigger use-after-free by repeatedly toggling the DAMON_STAT 'enabled' control after a damon_call() failure. Affected are kernels on the 6.17-6.19 line prior to the stable fixes; the flaw is classified CWE-416 (Use After Free). There is no public exploit identified at time of analysis, and EPSS is negligible (0.02%, 4th percentile).
Local privilege-escalation potential via a use-after-free in the Linux kernel's vub300 MMC host-controller driver (drivers/mmc/host/vub300.c), affecting kernels built with CONFIG_MMC_VUB300 through 6.17 and stable branches prior to 6.18.23/6.19.13. Because the controller structure was allocated with device-managed (devm) memory while the driver keeps its own explicit reference count, the last reference can outlive driver unbind, letting the kernel dereference freed memory on disconnect or probe deferral. No public exploit identified at time of analysis, and EPSS is negligible (0.02%), consistent with the requirement that the uncommon vub300 USB-to-SDIO hardware be physically present.
Use-after-free in Linux kernel's lan966x network driver allows local authenticated attackers to achieve arbitrary code execution with high impact to confidentiality, integrity, and availability. The flaw occurs in lan966x_fdma_reload() when RX buffer allocation fails - freed pages remain referenced by active DMA descriptors, causing hardware to write into memory now controlled by other kernel subsystems. Vendor patches available for stable branches 6.12.82, 6.18.23, 6.19.13, and mainline 7.0. EPSS score of 0.02% (5th percentile) indicates low probability of widespread exploitation. No CISA KEV listing or public exploit identified at time of analysis, but successful exploitation grants kernel-level privileges to local attackers.
Use-after-free in Linux kernel OCFS2 filesystem enables local attackers with low privileges to achieve arbitrary code execution, privilege escalation, or denial of service. The vulnerability occurs when filemap_fault() drops mmap_lock before returning VM_FAULT_RETRY, allowing concurrent munmap() to free the vm_area_struct while ocfs2_fault() still holds a dangling pointer. Vendor patches available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS exploitation probability is very low (0.02%, 5th percentile) with no public exploit identified at time of analysis.
Use-after-free in Linux kernel memory management allows remote code execution when the folio_unmap_invalidate() function incorrectly accesses freed mapping structures. Kernel versions between 1da177e4c3f4 and patches 6.19.14/7.0.1 are affected. Exploitation probability is low (EPSS 2%, percentile 5%), with no confirmed active exploitation or public POC at time of analysis. Despite the critical CVSS 9.8 score indicating network-based unauthenticated attack, the description suggests this is a kernel memory corruption bug requiring local kernel code paths to trigger, not direct remote network exploitation - CVSS vector conflicts with technical nature and should be validated against vendor guidance.
Use-after-free in Linux kernel KVM x86 MMIO emulation allows local authenticated users with low privileges to potentially execute arbitrary code, escalate privileges, or cause denial of service. The flaw occurs when KVM's emulator initiates MMIO writes using on-stack variables that cross page boundaries between two MMIO pages, creating dangling pointers when fragments are processed across separate KVM_RUN calls, especially when different tasks handle subsequent runs. EPSS exploitation probability is very low (0.02%, 5th percentile), and vendor patches are available for kernel versions 6.12.83, 6.18.24, 6.19.14, and 7.0.1. No active exploitation or public POC identified at time of analysis.
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 blk-cgroup subsystem allows local authenticated users to potentially execute arbitrary code, escalate privileges, or crash the system. The vulnerability occurs in cgwb_release_workfn() when releasing cgroup writeback structures, where a CSS reference is dropped before subsequent dereference, creating a race condition. Meta reports sporadic crashes in production across multiple kernel versions. Patches available for stable branches 6.12.83, 6.18.24, 6.19.14, and 7.0.1. EPSS score of 0.02% suggests low widespread exploitation probability, and no 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 escalation and denial of service in the Linux kernel's em28xx USB media driver arises from a use-after-free (CWE-416) in em28xx_v4l2_open(), which reads dev->v4l2 without holding dev->lock. A local attacker who can open the V4L2 device node during a race with the driver's init error path or teardown can trigger a use-after-free on the embedded video_device (via v4l2_fh_init accessing vdev->ctrl_handler) or a NULL dereference in em28xx_resolution_set(). No public exploit identified at time of analysis, and EPSS is very low (0.02%), consistent with a hard-to-win kernel race requiring physical/local USB device presence.
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.
Local privilege escalation and denial of service in the Linux kernel's bcache subsystem stems from a use-after-free of the cached_dev.sb_bio structure; if a cached backing device is stopped while a superblock write is in flight, the freed bio is dereferenced at I/O completion (endio), corrupting kernel memory. Affected systems are those running bcache-backed block devices (observed crashing via librbd/libceph rbd workloads), where a local user with the ability to trigger device teardown during superblock activity can crash the host or potentially corrupt kernel memory. This carries no public exploit identified at time of analysis and an EPSS of just 0.02%, consistent with a hard-to-time race rather than a readily weaponized flaw.
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.
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.
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.
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).
Sandbox escape in Google Chrome's DevTools component (versions prior to 147.0.7727.117) lets an attacker who has already compromised the renderer process break out of the browser sandbox via a crafted HTML page. Rated High by Chromium and CVSS 9.6, this is a use-after-free (CWE-416) that serves as the second link in a multi-stage exploit chain rather than a standalone remote code execution. No public exploit identified at time of analysis, EPSS is very low (0.03%), and CISA SSVC records no observed exploitation, so it is a patch-and-move-on desktop browser fix rather than an emergency.
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.
