The flaw affects all Linux kernel versions in the CPE range and has been resolved through reference counting fixes in the L2CAP connection cleanup path; no public exploit code is currently identified, but the vulnerability requires local access to trigger via Bluetooth device manipulation.

Use-after-free in Linux kernel Bluetooth L2CAP layer allows local attackers to cause denial of service or potentially execute code via a race condition in l2cap_unregister_user(). The vulnerability arises because l2cap_register_user() and l2cap_unregister_user() access conn->users without proper locking (conn->lock), while l2cap_conn_del() protects the same structure with conn->lock, creating concurrent access to freed memory. All Linux kernel versions with Bluetooth L2CAP support are affected. Patch available via Linux stable kernel commits.

Use-after-free in Linux kernel netfilter ctnetlink module allows local attackers to read freed kernel memory by triggering multiple-round netlink dump operations on conntrack expectations, exploiting improper reference counting in ctnetlink_dump_exp_ct() that drops conntrack references before the dump callback completes. The vulnerability requires local network namespace access and CAP_NET_ADMIN capability but enables information disclosure of kernel heap contents via KASAN-detected slab-use-after-free on ct->ext dereference.

Use-after-free in Linux kernel MANA hardware channel teardown (net/mana driver) allows concurrent interrupt handlers to dereference freed memory in mana_hwc_destroy_channel(), potentially causing NULL pointer dereference or memory corruption. The vulnerability stems from improper teardown ordering where hwc->caller_ctx is freed before CQ/EQ IRQ handlers are fully synchronized, affecting all Linux kernel versions with the MANA driver. Fixes are available across stable kernel branches via upstream commit reordering.

NULL dereference and use-after-free in the Linux kernel's SMC (Shared Memory Communications) socket implementation occur when smc_tcp_syn_recv_sock() races with socket close operations, allowing a local attacker to trigger a kernel panic via concurrent manipulation of TCP SYN handling and SMC listen socket closure. The vulnerability affects the Linux kernel across multiple versions via the net/smc subsystem and is addressed through RCU-protected access and refcount validation rather than lock-based serialization.

A use-after-free vulnerability in the Linux kernel's mshv (Microsoft Hyper-V) driver allows local attackers to trigger a kernel panic by unmapping user memory after a failed mshv_map_user_memory() call. The error path incorrectly calls vfree() without unregistering the associated MMU notifier, leaving a dangling reference that fires when userspace performs subsequent memory operations. This is a memory safety issue affecting the Hyper-V virtualization subsystem in the Linux kernel.

Use-after-free in the Linux kernel's in-kernel SMB server (ksmbd) lets an authenticated remote attacker corrupt kernel memory, crash the host, or potentially achieve kernel code execution by sending a single crafted compound SMB2 request. The flaw sits in the compound-request fast path: smb2_get_ksmbd_tcon() reuses work->tcon without re-validating tcon->t_state, so an earlier SMB2_TREE_DISCONNECT in the same compound frees share_conf and a later command such as SMB2_WRITE dereferences the freed object (KASAN slab-use-after-free in smb2_write). Affected systems are those running a vulnerable kernel with ksmbd loaded and at least one share exported, plus a valid SMB credential; ksmbd is not enabled by default on most distributions, EPSS is only 0.02% (7th percentile), and no public exploit identified at time of analysis.

Use-after-free in Linux kernel's ksmbd SMB server allows remote attackers to crash the kernel or potentially execute code via malicious SMB2 DURABLE_REQ_V2 replay operations. The vulnerability occurs when parse_durable_handle_context() unconditionally reassigns file handle connection pointers during replay operations, causing stale pointer dereferences when the reassigned connection is subsequently freed. A KASAN report confirms the use-after-free in spin_lock operations during file descriptor closure, triggered during SMB2 connection handling in the ksmbd-io workqueue. No public exploit code or active exploitation has been confirmed at time of analysis.

Interrupt storm in Linux kernel dpaa2-switch driver occurs when a bounds check rejects an out-of-bounds if_id in the IRQ handler but fails to clear the interrupt status, causing repeated spurious interrupts. This denial-of-service condition affects the NXP DPAA2 Ethernet switch driver on systems running vulnerable Linux kernel versions. An attacker with the ability to trigger malformed frames or hardware state transitions could exhaust CPU resources through interrupt flooding.

EPSS data not available; no public exploit identified at time of analysis. Vendor-released patches available across all affected major version branches.

Use-after-free in Electron's powerMonitor module allows local attackers to trigger memory corruption or application crashes through system power events. All Electron applications (versions <38.8.6, <39.8.1, <40.8.0, <41.0.0-beta.8) that subscribe to powerMonitor events (suspend, resume, lock-screen) are vulnerable when garbage collection frees the PowerMonitor object while OS-level event handlers retain dangling pointers. Exploitation requires local access and specific timing conditions (CVSS 7.0 HIGH, AC:H). No public exploit identified at time of analysis, though the technical details are publicly documented in the GitHub security advisory.

Use-after-free vulnerability in Linux kernel futex handling allows local attackers to read freed memory via race condition between futex_key_to_node_opt() and vma_replace_policy(). When mbind() concurrently replaces virtual memory area policies, __futex_key_to_node() may dereference a freed mempolicy structure, enabling information disclosure of kernel memory. The vulnerability requires local access and precise timing but poses memory safety risk in multi-threaded applications using futex operations alongside memory policy changes.

Use-after-free in Linux kernel clsact qdisc initialization and destruction rollback allows local denial of service or potential information disclosure when qdisc replacement fails midway during tcf_block_get_ext() operations. The vulnerability stems from asymmetric initialization and cleanup paths where egress_entry references from a previous clsact instance remain valid during failure scenarios, leading to double-free or use-after-free conditions. Affected Linux kernel versions across all distributions that include the clsact traffic control qdisc require patching.

Use-after-free in Linux kernel netfilter BPF hook memory management allows local attackers to read sensitive kernel memory via concurrent nfnetlink_hooks dumping operations. The vulnerability arises from premature memory release in hook structures before RCU readers complete their access, enabling information disclosure through netlink interface. No active exploitation confirmed, but the KASAN report demonstrates reliable reproducer availability.

This vulnerability affects all Linux kernel versions with the vulnerable nf_tables code and was discovered via KASAN reports during hook dumping operations; while not currently listed in known exploited vulnerabilities (KEV) databases, the use-after-free nature presents a real risk for denial of service or information disclosure in environments utilizing netfilter flowtables.

A buffer overflow vulnerability exists in the Linux kernel's dma_map_sg tracepoint that can be triggered when tracing large scatter-gather lists, particularly with devices like virtio-gpu that create large DRM buffers exceeding 1000 entries. The vulnerability affects all Linux kernel versions prior to the fix and can cause perf buffer overflow warnings and potential kernel instability when dynamic array allocations exceed PERF_MAX_TRACE_SIZE (8192 bytes). While this is a kernel-level issue requiring local access to trigger tracing functionality, it poses a denial-of-service risk and memory safety concern for systems using performance tracing on workloads with large scatter-gather operations.

A buffer overflow vulnerability exists in the Linux kernel's IFE (Intermediate Functional Element) traffic control action module where metadata list replacement incorrectly appends new metadata instead of replacing old entries, causing unbounded metadata accumulation. This affects all Linux kernel versions with the vulnerable IFE scheduling code (cpe:2.3:a:linux:linux). An attacker with the ability to modify traffic control rules can trigger an out-of-bounds write via the ife_tlv_meta_encode function, potentially achieving kernel memory corruption and denial of service. The vulnerability is not listed as actively exploited in public KEV databases, but patches are available across multiple stable kernel branches.

This vulnerability is a race condition in the Linux kernel's PCI Designware endpoint driver where MSI-X interrupt writes to the host can complete after the corresponding Address Translation Unit (ATU) entry is unmapped, potentially corrupting host memory or triggering IOMMU errors. The vulnerability affects all Linux kernel versions with the vulnerable code path in the PCI DWC endpoint implementation (cpe:2.3:a:linux:linux:*:*:*:*:*:*:*:*), specifically impacting systems using PCI endpoint devices with MSI-X interrupt support such as NVMe-PCI endpoint function drivers. An attacker with the ability to trigger high-frequency MSI-X interrupts from a malicious endpoint device could exploit this race condition to cause denial of service through IOMMU faults or potentially corrupt host memory.

A stack-out-of-bounds write vulnerability exists in the Linux kernel's BPF devmap implementation where the get_upper_ifindexes() function iterates over upper network devices without properly validating buffer bounds. An attacker with the ability to create multiple virtual network devices (e.g., more than 8 macvlans) and trigger XDP packet processing with BPF_F_BROADCAST and BPF_F_EXCLUDE_INGRESS flags can write beyond allocated stack memory, potentially causing denial of service or arbitrary code execution. The vulnerability affects all Linux kernel versions using the vulnerable devmap code path and has been patched across multiple stable kernel branches, indicating recognition as a real security concern requiring immediate updates.

Use-after-free in Linux kernel's netfilter nft_set_pipapo enables local privilege escalation to kernel-level access (confidentiality/integrity/availability compromise). Affects Linux kernel 5.6+ through multiple stable branches (6.1.x, 6.6.x, 6.12.x, 6.18.x, 6.19.x). Vendor patches available across all affected kernel series. EPSS score of 0.03% (9th percentile) indicates low automated exploitation likelihood, consistent with local-access requirement and lack of public exploit code at time of analysis.

A use-after-free vulnerability exists in the Linux kernel's crypto subsystem (CCP driver) within the sev_tsm_init_locked() function error path, where a pr_err() statement dereferences freed memory to access structure fields t->tio_en and t->tio_init_done after kfree(t) has been executed. This vulnerability can lead to information disclosure by reading freed memory contents. The issue affects Linux kernel versions across distributions using the affected CCP crypto driver code and was identified by the Smatch static analyzer.

A memory corruption vulnerability exists in the Linux kernel's XDP (eXpress Data Path) subsystem where negative tailroom calculations are incorrectly reported as large unsigned integers, allowing buffer overflows during tail growth operations. This affects Linux kernel versions across multiple stable branches when certain Ethernet drivers (notably ixgbevf) report incorrect DMA write sizes, leading to heap corruption, segmentation faults, and general protection faults as demonstrated in the xskxceiver test utility. The vulnerability has no CVSS score assigned and shows no active KEV exploitation status, but represents a critical memory safety issue affecting systems using XDP with affected Ethernet drivers.

Use-after-free in Linux kernel network traffic control subsystem allows local authenticated attackers to execute arbitrary code with high privileges when changing network queue pair configurations on lockless qdiscs (virtio-net confirmed affected). Race condition between qdisc_reset_all_tx_gt() and dequeue operations causes memory to be freed while still in use. Vendor-released patches available for stable kernel branches 6.1.167, 6.6.130, 6.12.77, 6.18.17, 6.19.7, and mainline 7.0-rc3. EPSS exploitation probability is low (0.02%, 7th percentile) and no active exploitation confirmed at time of analysis, though a reliable reproducer exists using iperf3 and ethtool queue manipulation.

Use-after-free in Linux kernel cfg80211 WiFi subsystem allows local authenticated users with low privileges to achieve high impact on confidentiality, integrity, and availability through rfkill work-queue exploitation. The vulnerability affects Linux kernel versions 2.6.31 through 6.19-rc2, with patches released for stable branches 6.1.167, 6.6.130, 6.12.77, 6.18.17, 6.19.7, and 7.0-rc2. EPSS score of 0.02% (7th percentile) indicates very low probability of mass exploitation. No CISA KEV listing or public exploit identified at time of analysis, though the issue was discovered via syzkaller fuzzing, demonstrating automated exploit development potential.

This vulnerability is a memory leak in the Linux kernel's AF_XDP socket implementation where buffers fail to be properly returned to the free list due to improper list node reinitialization. The vulnerability affects all Linux kernel versions with the AF_XDP subsystem enabled, potentially allowing local attackers or unprivileged users to exhaust kernel memory over time. While not actively exploited in the wild according to available intelligence, the vulnerability has clear patches available in stable kernel branches and represents a real denial-of-service risk for systems relying on XDP functionality.

The Apple Silicon SMC hwmon driver (macsmc-hwmon) in the Linux kernel contains critical memory safety bugs in sensor population and float conversion logic. Specifically, voltage sensors are incorrectly registered to the temperature sensor array, and float-to-32-bit conversion has flawed exponent handling, potentially leading to out-of-bounds memory access, data corruption, or incorrect fan control on affected Apple Silicon systems. The vulnerability affects Linux kernel versions with the macsmc-hwmon driver and has been patched; no active exploitation or POC is currently known, but the nature of the bugs suggests high real-world risk for systems relying on thermal management.

A use-after-free and list corruption vulnerability exists in the Linux kernel's IPMI (Intelligent Platform Management Interface) subsystem when the SMI sender returns an error. The vulnerability affects all Linux kernel versions with the vulnerable IPMI code path, allowing local attackers or processes with IPMI access to trigger denial of service conditions through list corruption and NULL pointer dereferences. The vulnerability is not currently listed in CISA's KEV catalog, and no CVSS or EPSS scores have been published; however, the technical nature indicates high reliability for exploitation by local actors with kernel interface access.

A use-after-free (UAF) vulnerability exists in the Linux kernel's BPF subsystem within the bpf_trampoline_link_cgroup_shim function, where a race condition allows a process to reference memory after it has been freed. An attacker with CAP_BPF or CAP_PERFMON capabilities can trigger this vulnerability to cause a kernel crash (denial of service). A proof-of-concept has been demonstrated by the reporter, showing the bug can be reliably reproduced; the vulnerability is not listed on the CISA KEV catalog but affects all Linux kernel versions until patched.

A use-after-free vulnerability exists in the Linux kernel's pm8001 SCSI driver where the pm8001_queue_command() function incorrectly returns -ENODEV after already freeing a SAS task, causing the upper-layer libsas driver to attempt a second free operation. This affects all Linux kernel versions with the vulnerable pm8001 driver code, and while not remotely exploitable by default, it can lead to kernel memory corruption and denial of service on systems using PM8001-compatible SCSI controllers. No CVSS score, EPSS data, or active KEV status is currently available, but multiple stable kernel patches have been released across multiple branches.

Use-after-free in the Linux kernel's libertas wireless driver (lbs_free_adapter()) allows local privileged users to corrupt memory when a timer callback races with adapter teardown. The flaw stems from using non-synchronous timer_delete() instead of timer_delete_sync() on command_timer and tx_lockup_timer, leaving callbacks free to dereference freed driver_lock, cur_cmd, and dev fields. EPSS is very low (0.02%, 7th percentile) and there is no public exploit identified at time of analysis, but the bug has existed since the driver's introduction and on stable trees through 6.18.x.

Improper bounds checking in Apple macOS (Sequoia 15.7.4 and earlier, Sonoma 14.8.4 and earlier, Tahoe 26.3 and earlier) permits a local attacker to write out-of-bounds memory through a malicious application, potentially allowing modification of protected filesystem areas. The vulnerability requires user interaction to execute the malicious app and affects the file system's integrity rather than confidentiality. No patch is currently available for this out-of-bounds write condition.

Apple's iOS, iPadOS, macOS, tvOS, and watchOS contain a use-after-free vulnerability that could allow a local attacker to corrupt kernel memory or cause unexpected system crashes. An installed application can trigger this memory corruption flaw through user interaction, potentially leading to denial of service or unauthorized kernel-level modifications.
