No public exploit identified at time of analysis, and the issue is not present on the CISA KEV list.

Use-after-free in the Linux kernel SPI controller driver for Freescale MPC52xx (spi-mpc52xx) occurs when controller registration fails and the previously requested interrupts are not properly disabled or released, leaving dangling interrupt handlers tied to freed memory. Local users with the ability to load or interact with this SPI driver on affected systems could potentially trigger memory corruption or information disclosure. EPSS is 0.02% and there is no public exploit identified at time of analysis, but the issue is rated CVSS 7.8 due to high impact on confidentiality, integrity, and availability.

Local privilege escalation potential via use-after-free in Linux Kernel iris media driver affects kernels 6.18.16-6.18.31, 6.19.6-6.19.x, and 7.0 series prior to the fix commits. The flaw resides in iris_release_internal_buffers(), where session_release_buf() may free a buffer that the caller subsequently dereferences, a regression introduced by commit 1dabf00ee206. No public exploit identified at time of analysis and EPSS probability is very low (0.02%), but local low-privileged attackers on systems with the Qualcomm iris video accelerator driver could potentially leverage the freed-memory access.

Local privilege escalation in the Linux kernel's vsock (virtio sockets) subsystem stems from inverted buffer-size clamping logic in vsock_update_buffer_size(), allowing a local user to grow vsk->buffer_size beyond the configured vsk->buffer_max_size and violate intended socket memory boundaries. Affected branches include stable trees prior to 6.6.140, 6.12.90, 6.18.32, 7.0.9, and 7.1-rc1; no public exploit identified at time of analysis and EPSS is 0.02% (5th percentile).

Local privilege escalation in the Linux kernel SCTP subsystem allows unprivileged users to trigger a use-after-free or type confusion in the SCTP_SENDALL code path. The flaw stems from a stale iterator cursor in sctp_sendmsg() that survives across a dropped socket lock, and the type-confusion variant yields a controlled indirect call via outqueue.sched->init_sid. No public exploit identified at time of analysis, and EPSS is very low (0.02%), but the vendor description explicitly notes both bugs are reachable from CapEff=0.

Use-after-free in the Linux kernel's MPC52xx SPI driver (spi-mpc52xx) can be triggered when the driver is unbound, because the interrupt-scheduled state machine work is not cancelled after interrupts are disabled. Local users with the ability to unbind the driver could potentially corrupt kernel memory, with confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and EPSS exploitation probability is very low at 0.02%.

Use-after-free in the Linux kernel's DRM (Direct Rendering Manager) GEM handle subsystem allows a local authenticated attacker to trigger memory corruption via a race condition in the change_handle ioctl. The flaw stems from a window where a single GEM object briefly held two IDR entries, letting a concurrent gem_close call dereference a dangling handle. No public exploit identified at time of analysis and EPSS exploitation probability is low (0.02%), but the CVSS 7.8 reflects full confidentiality, integrity, and availability impact on affected systems.

Use-after-free in the Linux kernel's appletb-kbd HID driver allows local low-privileged users on Apple Touch Bar-equipped MacBooks to potentially trigger memory corruption during driver tear-down. The flaw stems from incorrect ordering of timer cleanup and device reference release in the inactivity-timer cleanup path, leaving two race windows where a softirq can dereference freed backlight_device memory. EPSS is very low (0.02%) and no public exploit identified at time of analysis; impact is limited to systems running the appletb-kbd driver, primarily Apple MacBook Pro hardware with Touch Bars.

Use-after-free in the Linux kernel's batman-adv (B.A.T.M.A.N. Advanced) mesh networking module's bridge loop avoidance (BLA) subsystem allows adjacent attackers on the same Layer-2 segment to potentially trigger memory corruption when claim entries are deleted. The flaw, with a CVSS of 8.8 (AV:A/AC:L/PR:N/UI:N), exists in batadv_bla_del_backbone_claims() where a claim reference may be released before its final use, enabling exploitation by anyone able to inject mesh traffic. EPSS is very low (0.02%) and no public exploit identified at time of analysis, but upstream fixes have been released across multiple stable kernel branches.

Local privilege escalation and memory corruption in the Linux kernel's iris media driver allows local users with low privileges to trigger a use-after-free condition via concurrent access during Macro Blocks Per Frame (MBPF) checks. The flaw affects Linux kernel 6.18 and stems from improper lock ordering where fmt_src and fmt_dst structures are freed under inst->lock while the instance remains in the core list traversed under core->lock. EPSS is very low at 0.02% (5th percentile) and no public exploit identified at time of analysis, but the high CVSS score reflects severe local impact.

Local privilege escalation potential exists in the Linux kernel's DRM/GEM framebuffer subsystem (drm_gem_fb_init_with_funcs) where inconsistent plane dimension calculations between integer division and DIV_ROUND_UP cause a size-check bypass. A local low-privileged user able to invoke the framebuffer ioctl with specific pixel formats (e.g., NV12) and crafted dimensions can trigger an out-of-bounds GPU memory access on the chroma plane, leading to memory corruption with high confidentiality, integrity, and availability impact. No public exploit identified at time of analysis, and EPSS is very low (0.02%), suggesting limited near-term exploitation risk despite the 7.8 CVSS.

Local privilege escalation via out-of-bounds buffer access in the Linux kernel's AMD KFD (Kernel Fusion Driver) SVM ioctl interface allows authenticated local users to corrupt kernel memory by supplying an attacker-controlled nattr attribute count that exceeds the buffer size. The flaw affects systems running AMD GPUs with the amdkfd driver and has been resolved upstream across multiple stable branches. EPSS is very low (0.02%, 5th percentile) and there is no public exploit identified at time of analysis, but the high CIA impact warrants prompt patching on AMD GPU compute workstations and HPC nodes.

Local privilege escalation risk in the Linux kernel's brcmfmac Broadcom FullMAC Wi-Fi driver stems from a use-after-free in the watchdog kthread teardown path, where the watchdog task can exit between send_sig() and kthread_stop(), leaving stale memory accessible. Successful exploitation by a local low-privileged attacker who can trigger driver teardown could yield kernel memory corruption with high confidentiality, integrity, and availability impact (CVSS 7.8). No public exploit identified at time of analysis and EPSS is very low (0.02%), suggesting limited near-term exploitation interest.

Memory corruption in the Linux kernel scheduler exit path allows local low-privileged users to trigger use-after-free or double-free of task stacks when an exiting task oopses, per CVE-2026-46173. The flaw stems from make_task_dead() invoking do_task_dead() with preemption enabled, violating the scheduler's requirement that __schedule() run with preemption disabled, which can leave two tasks running on the same stack. No public exploit identified at time of analysis, and EPSS rates exploitation probability at just 0.02%.

Use-after-free in the Linux kernel mac80211 wireless subsystem allows attackers on the adjacent wireless network to corrupt kernel memory by triggering radar detection cancellation paths that free a channel context still being iterated. No public exploit identified at time of analysis, and EPSS exploitation probability is 0.02% (5th percentile), but the high CVSS reflects severe potential impact on confidentiality, integrity, and availability if exploited. A vendor-released patch is available in stable kernel updates including 6.12.88, 6.18.30, and 7.0.7.

Local privilege escalation potential exists in the Linux kernel's sched_ext (SCX) subsystem where a use-after-free condition in cgroup setter operations can be triggered when a BPF scheduler is swapped concurrently with cgroup weight, idle, or bandwidth updates. The flaw affects kernel 6.18 and related stable branches and stems from reading scx_root outside the scx_cgroup_ops_rwsem, allowing a stale pointer to be dereferenced after the previous scheduler is freed via RCU. EPSS is very low (0.02%) and no public exploit is identified at time of analysis.

Local privilege escalation in the Linux kernel's RDMA/mana driver allows an authenticated low-privileged user to corrupt kernel memory by supplying an oversized rx_hash_key_len via the uAPI structure, which is passed unchecked to memcpy. The flaw affects kernels using the Microsoft Azure Network Adapter (MANA) RDMA driver and can lead to heap/stack overflow within kernel space, enabling potential code execution or system compromise. No public exploit identified at time of analysis, and EPSS is very low at 0.02% (5th percentile), indicating limited exploitation interest so far.

Denial-of-service in the Linux kernel mt76/mt7921 MediaTek Wi-Fi driver lets a buffer-length (buf_len) underflow occur while iterating the CLC (country location configuration) power table, producing a near-infinite loop or an invalid power setting that crashes driver initialization. Systems running affected kernels with MediaTek MT7921 Wi-Fi hardware are impacted; classified CWE-787 (out-of-bounds write) with a vendor-assigned CVSS of 7.8 (local, AV:L). No public exploit identified at time of analysis and EPSS is very low (0.02%), consistent with a reliability/DoS defect rather than a readily weaponizable memory-corruption primitive.

Use-after-free/double-free in the Linux kernel's mac80211 wireless subsystem affects systems with Multi-Link Operation (MLO) Wi-Fi connections when debugfs is enabled. The flaw occurs when connection preparation fails for MLO connections and the interface is reset to non-MLD without removing the associated station, corrupting debugfs state. EPSS probability is 0.02% (5th percentile) and no public exploit identified at time of analysis, but the CVSS 8.8 score reflects high impact on adjacent-network reachable systems.

Out-of-bounds read and information disclosure in the Linux kernel's virtio_bt (virtio Bluetooth) driver allows a malicious or buggy virtio backend to leak uninitialized kernel heap memory into received Bluetooth skbs. The virtbt_rx_work() function trusted the device-reported length from virtqueue_get_buf() without clamping it to the 1000-byte buffer actually exposed via sg_init_one(), so a hostile backend can report lengths between 1001 and skb_tailroom() - or 0 - causing skb_put() to expose untouched heap bytes or virtbt_rx_handle() to read an uninitialized pkt_type. No public exploit identified at time of analysis and EPSS is 0.02% (5th percentile), but a vendor patch is available.

Use-after-free in the Linux kernel's DAMON sysfs interface (mm/damon/sysfs-schemes) lets a local actor with access to the 'memcg_path' file race a read against a concurrent write that frees the underlying buffer, accessing freed kernel memory. The flaw affects DAMON-enabled builds across the 6.6.96, 6.12.36, 6.15.5 and 6.16-rc lines, and is fixed by serializing both direct reads and writes under damon_sysfs_lock. EPSS is negligible (0.02%, 5th percentile) and there is no public exploit identified at time of analysis; it is not in CISA KEV.

Local privilege escalation and kernel memory corruption in the Linux kernel's IPv6 GRE (ip6_gre) subsystem stem from ip6erspan_changelink() using dev_net(dev) instead of the cached t->net after IFLA_NET_NS_FD migration, causing a tunnel to be re-inserted into the wrong per-netns hash. When the original network namespace is later destroyed, the stale entry triggers a slab-use-after-free (flagged by KASAN) and a kernel BUG at LIST_POISON1, reachable from an unprivileged user namespace. No public exploit identified at time of analysis, though the bug is trivially reachable via unshare and EPSS exploitation probability is low (0.02%).

Use-after-free in the Linux kernel's xfrm (IPsec) state management subsystem allows local attackers with low privileges to trigger memory corruption via concurrent xfrm_state lifecycle operations. The flaw resides in __xfrm_state_delete() where value-based predicates on x->km.seq and x->id.spi can race with xfrm_alloc_spi() outside of xfrm_state_lock, leading to slab-use-after-free writes through LIST_POISON pointers on the byseq/byspi/bydst/bysrc hash chains. No public exploit identified at time of analysis, and EPSS is very low at 0.02% (5th percentile), but a vendor patch is available.

Use-after-free in the Linux kernel's KVM x86 shadow MMU allows a malicious guest VM to corrupt host memory and potentially escalate privileges on the hypervisor. The flaw occurs when a guest modifies its page tables between VM entries, causing KVM to install rmap entries outside the expected GFN range of a direct-mapped shadow page; subsequent rmap walks (e.g., during dirty logging or MMU notifier invalidations from MADV_DONTNEED) then dereference a freed kvm_mmu_page. EPSS is very low (0.02%) and no public exploit identified at time of analysis, but the bug has existed since the earliest KVM versions and is now patched upstream.

Local privilege escalation potential in the Linux kernel Bluetooth subsystem (hci_conn) stems from a use-after-free in create_big_sync() when a Broadcast Isochronous Group (BIG) creation races against connection teardown. A local low-privileged attacker on a system with active Bluetooth LE Audio operations could trigger the freed hci_conn dereference through hci_connect_cfm()/hci_conn_del(), enabling memory corruption with high impact to confidentiality, integrity, and availability. No public exploit identified at time of analysis, and EPSS is very low (0.02%, 5th percentile), reflecting limited weaponization despite the CVSS 7.8 rating.

Out-of-bounds write in Samsung's Escargot JavaScript engine allows attacker-supplied scripts to corrupt memory through the ArrayBuffer.prototype.transfer() built-in, with high confidentiality, integrity, and availability impact (CVSS 8.8). The flaw stems from a missing length-bounds check when transferring an ArrayBuffer to a new byte length, enabling writes past the allocated buffer that can lead to remote code execution if a victim runs the malicious script. No public exploit has been identified at time of analysis, and no EPSS or CISA KEV data was provided.

Out-of-bounds write in LibVNCClient (shipped in the LibVNCServer project, versions 0.9.15 and earlier) lets a malicious or compromised VNC server corrupt memory in any client that connects to it. The Tight encoding decoder's Gradient filter uses fixed 2048-pixel scratch buffers but never validates the server-supplied rectangle width, so a crafted FramebufferUpdate with a width above 2048 overruns those buffers, threatening confidentiality, integrity, and availability (CVSS 8.8). There is no public exploit identified at time of analysis and it is not listed in CISA KEV; the issue is fixed by upstream commit 5b270544.

Use-after-free in the Linux kernel's edt-ft5x06 capacitive touchscreen driver (CWE-416) lets a local actor with access to the driver's per-client debugfs interface read or corrupt freed kernel memory during device teardown. The regression was introduced by commit 68743c500c6e, which removed manual debugfs cleanup and left a window where debugfs files referencing tsdata->raw_buffer remained accessible after the buffer was freed. No public exploit identified at time of analysis; EPSS is very low (0.02%, 4th percentile) and it is not in CISA KEV, but a vendor (stable-tree) patch is available.

Local privilege escalation potential via use-after-free in the Linux kernel's ALSA aloop (snd-aloop) driver allows authenticated local users to trigger memory corruption by racing PCM stream close against a peer format-change stop. The flaw stems from snd_pcm_stop() running after cable->lock is dropped, leaving a stale peer substream pointer that can be freed by a concurrent close. Upstream fixes are merged into stable trees (6.12.88, 6.18.27, 7.0.4, 7.1-rc2); no public exploit identified at time of analysis and EPSS is very low at 0.02%.

Use-after-free in the Linux kernel's RDMA mana_ib driver (Microsoft Azure Network Adapter) lets a local user trigger stale firmware RX steering after destroying an RSS QP, so incoming completions land on reused CQ IDs and corrupt kernel state. It affects Linux deployments on Azure VMs using MANA with RDMA/DPDK; an attacker who can create and destroy RSS QPs (e.g., via a DPDK application exit while a peer keeps transmitting) can drive completions onto TX CQs and crash or corrupt the driver. There is no public exploit identified at time of analysis and EPSS is negligible (0.02%, 5th percentile), indicating low real-world exploitation likelihood.

Local privilege escalation via memory corruption in Linux Kernel crypto subsystem (acomp) affects systems using asynchronous hardware compression accelerators such as Intel QAT. The flaw stems from acomp_save_req() storing the wrong pointer (&req->chain instead of req itself) in req->base.data, causing the completion callback acomp_reqchain_done() to dereference fields at incorrect offsets. No public exploit identified at time of analysis, and EPSS is very low at 0.02%, but the high CVSS (7.8) reflects potential for memory corruption with high confidentiality, integrity, and availability impact.

Local privilege escalation and memory corruption in the Linux kernel's atmel-sha204a crypto driver allows an attacker who can remove or unbind the device to trigger a use-after-free during the driver teardown path. The flaw stems from failing to unregister the hwrng and flush the Atmel I2C workqueue before teardown, letting a queued ->read() callback execute against freed state, and an early return that also leaks the hwrng.priv allocation. EPSS is very low (0.02%) and there is no public exploit identified at time of analysis, so this is a defense-in-depth hardening fix rather than an urgent emergency.

Out-of-bounds read in the Linux kernel md/raid5 journal recovery path allows a local privileged user supplying a corrupted MD RAID5 journal device to trigger memory disclosure or kernel crashes during journal replay. The flaw exists in r5c_recovery_analyze_meta_block() and r5l_recovery_verify_data_checksum_for_mb(), which trusted on-disk payload size fields without validating them against the metadata block's remaining space. No public exploit identified at time of analysis, and EPSS scores exploitation probability at just 0.02% (5th percentile).

Use-after-free in the Linux kernel's mwifiex Wi-Fi driver (Marvell) occurs during adapter teardown: mwifiex_adapter_cleanup() calls the non-synchronous timer_delete() on the wakeup_timer, so a still-running wakeup_timer_fn callback can dereference adapter fields (hw_status, if_ops.card_reset) after mwifiex_free_adapter() frees them along the card-removal path. A local attacker who can trigger device removal while the timer fires could corrupt freed kernel memory, enabling privilege escalation or denial of service. There is no public exploit identified at time of analysis, EPSS is negligible (0.02%, 5th percentile), and the fix (timer_delete_sync()) is merged into stable releases.

Improper memory deallocation in the Linux kernel's NX-842 hardware compression crypto driver (nx842_crypto_alloc_ctx/free_ctx) causes bounce buffers allocated as order-2 (4 pages) to be released with single-page free_page() calls, leaking three of every four pages. The flaw is local-only with no public exploit identified at time of analysis, and EPSS (0.02%, 5th percentile) reflects negligible mass-exploitation interest. Note that the NVD CVSS (7.8, C:H/I:H/A:H) appears overstated for what the upstream commit explicitly describes as a memory leak rather than corruption.

Use-after-free in the Linux kernel Bluetooth subsystem (hci_event) allows an adjacent attacker within Bluetooth range to potentially achieve memory corruption against vulnerable hosts during SSP pairing. The flaw stems from missing hdev locking in hci_user_passkey_notify_evt() and hci_keypress_notify_evt(), where an hci_conn structure can be freed concurrently while still in use. No public exploit identified at time of analysis, and EPSS exploitation probability is very low (0.02%).

Use-after-free in the Linux kernel's QRTR (Qualcomm IPC Router) name service driver remove path allows local low-privileged users to corrupt memory and potentially escalate privileges. The flaw occurs because qrtr_ns_data_ready() can queue work to a workqueue that has already been destroyed during driver teardown, dereferencing freed memory. No public exploit identified at time of analysis, EPSS is very low (0.02%), and the fix has landed across multiple stable kernel trees.

Data corruption in the Linux kernel md-llbitmap RAID subsystem allows stale bitmap pages to be read from spare disks during rebuild. The md-llbitmap code iterated rdevs checking only raid_disk assignment and the Faulty flag, omitting the In_sync flag, so bitmap data could be sourced from a not-yet-synchronized spare. No public exploit identified at time of analysis and EPSS exploitation probability is negligible (0.02%), but the bug can silently corrupt arrays during normal operation or recovery.

Local privilege escalation in the Linux kernel's vfio/cdx (Composable DMA-capable eXtension) driver allows a process with access to a VFIO device file descriptor to trigger a use-after-free of the cdx_irqs array via concurrent VFIO_DEVICE_SET_IRQS ioctls. The race in vfio_cdx_set_msi_trigger() can be exploited by a local low-privileged attacker for memory corruption with high confidentiality, integrity, and availability impact (CVSS 7.8). There is no public exploit identified at time of analysis and EPSS is very low (0.02%, 5th percentile).

Local privilege escalation and memory corruption in the Linux kernel's MediaTek JPEG (mtk-jpeg) media driver allows a local user with access to the device to trigger a use-after-free condition. The flaw occurs in mtk_jpeg_release() which frees the context structure without first cancelling pending workqueue items, creating a race window during device close where the worker thread accesses freed memory. No public exploit identified at time of analysis, and EPSS rates exploitation probability at just 0.02%, but the bug is fixed across multiple stable trees.

Local privilege escalation potential in the Linux kernel's Nouveau DRM driver stems from a 32-bit integer overflow in the pushbuf relocation bounds check (nouveau_gem_pushbuf_reloc_apply). Authenticated local users with access to the Nouveau GPU device node can bypass the size validation and trigger out-of-bounds writes against the buffer object, leading to high impact on confidentiality, integrity, and availability. No public exploit identified at time of analysis, and EPSS is very low (0.02%), but a vendor patch is available across multiple stable kernel branches.

Use-after-free in the Linux kernel ALSA caiaq USB audio driver allows local code execution when the device probe path encounters an error during setup_card(). The setup_card() function previously ignored failures from snd_card_register() and continued executing, leaving freed card structures accessible to subsequent initialization calls such as snd_usb_caiaq_control_init(). No public exploit identified at time of analysis, and EPSS is low at 0.02% (5th percentile), consistent with the local attack vector and narrow hardware-driver scope.

Stack buffer overrun in the Linux kernel's pt5161l hwmon driver allows a malicious or malfunctioning I2C device to write up to 32 bytes into a 24-byte stack buffer during pt5161l_read_block_data(), corrupting kernel memory. The flaw affects Linux 6.9 through versions before the stable fixes, and a secondary bug causes the driver to process stale data as valid when retries are exhausted with a length mismatch. EPSS is very low (0.02%) and no public exploit identified at time of analysis.

Use-after-free in the Linux kernel's rxrpc (AF_RXRPC) networking subsystem allows local attackers with low privileges to trigger memory corruption when skb_unshare() fails during packet input handling. Affected Linux kernel versions from 6.2 up to the fixed releases can be exploited to cause a NULL-pointer oops and potentially escalate privileges or crash the system. No public exploit identified at time of analysis; EPSS is very low (0.02%) and the issue is not present in CISA KEV.

Use-after-free in the Linux kernel's i.MX SPI driver (spi-imx) can be triggered when the driver is unbound, allowing a local privileged user to corrupt kernel memory and potentially escalate to full kernel code execution. EPSS is very low (0.02%) and no public exploit identified at time of analysis, but a kernel-level UAF with high CIA impact warrants prompt patching on affected i.MX-based systems.

Use-after-free in the Linux kernel's io_uring zero-copy receive (zcrx) subsystem allows local low-privileged attackers to corrupt memory and potentially escalate privileges. The flaw stems from io_free_rbuf_ring() accessing a struct user_struct after io_zcrx_ifq_free() has already released the reference, creating a UAF window. No public exploit identified at time of analysis and EPSS probability is very low (0.02%), but the bug class (UAF in io_uring) has historically been weaponized for LPE.

Heap out-of-bounds write in the Linux kernel UDF filesystem driver allows a local attacker to corrupt kernel memory by mounting a crafted UDF image containing repeated partition descriptors. The flaw stems from incorrect bookkeeping in handle_partition_descriptor() where appended slots never record partnum, causing duplicate descriptors to overflow the part_descs_loc[] table. No public exploit identified at time of analysis, and EPSS scores the exploitation probability at only 0.02%.

Use-after-free in the Linux kernel's Open Firmware (OF) device tree unittest driver (testdrv_probe) allows local low-privileged attackers to corrupt memory and potentially escalate privileges. The flaw stems from an erroneous of_node_put() call that releases a device_node reference owned by the device model, which can then be dereferenced later in of_platform_default_populate(). EPSS is very low (0.02%) and no public exploit identified at time of analysis, but a vendor patch is available.

Local privilege escalation potential in the Linux kernel's GFS2 filesystem stems from a use-after-free in the inline data write path of gfs2_iomap_begin(), where the inode buffer head is released before iomap->inline_data is consumed by iomap_write_end_inline(). Local users with the ability to write to a GFS2-backed filesystem can trigger memory corruption via a freed page that kswapd has since reclaimed. No public exploit identified at time of analysis, EPSS probability is very low (0.02%), and the issue is not listed in CISA KEV, but vendor patches across multiple stable trees are available.

Local privilege escalation and denial of service in the Linux kernel's AMD XDNA (amdxdna) accelerator driver allows authenticated local users to trigger a use-after-free condition by submitting jobs to a hardware context concurrently with resource release. The flaw affects kernels in the 6.14.9 through 6.15 series and was resolved upstream by stopping job scheduling around aie2_release_resource() and validating context state in aie2_sched_job_run(). No public exploit identified at time of analysis, and EPSS scoring (0.02%) indicates negligible near-term exploitation probability.

Use-after-free and double-free conditions in the Linux kernel's SMB client (smb2_open_file) can be triggered when SMB2_open() retry paths fail to zero out err_iov and err_buftype buffers, leading to memory corruption. The flaw affects multiple stable kernel branches (6.1, 6.6, 6.12, 6.18) and is fixed in upstream patches; no public exploit identified at time of analysis and EPSS is very low (0.02%) despite the 9.8 CVSS score.

Use-after-free in the Linux kernel bonding driver's Adaptive Load Balancing (ALB) subsystem allows a local low-privileged user to crash the kernel by racing rlb_arp_recv() against rlb_deinitialize() during rapid bond interface up/down cycling. Specifically, the RX handler continues to dereference rx_hashtbl entries after rlb_deinitialize() frees them, because recv_probe is set to NULL without first draining in-flight softirq handlers via synchronize_net(). Systems running bonded NICs in ALB mode (mode=6) on affected kernel versions - including Dell PowerEdge hardware and Canonical-distributed kernels - are at risk of kernel panic. No public exploit identified at time of analysis, and EPSS at 0.02% (7th percentile) confirms no observed mass exploitation.

Local privilege escalation and memory corruption in the Linux kernel's Exynos DRM VIDI (Virtual Display) driver allows local users with access to the DRM device to trigger null pointer dereferences, garbage value accesses, out-of-bounds reads, or use-after-free conditions via the vidi_connection_ioctl() handler. The flaw stems from an incorrect device-to-context lookup that retrieves driver_data from the exynos-drm master device instead of the VIDI component device. A vendor patch is available across multiple stable branches, no public exploit identified at time of analysis, and EPSS rates exploitation probability at only 0.02%.

Local privilege escalation in the Linux kernel's BPF subsystem stems from incorrect refcounting in check_pseudo_btf_id() that can leave a BTF (BPF Type Format) object with a zero refcount while still in use, creating a use-after-free condition. Affected kernels (around 6.14 through pre-patch 6.18.14/6.19.4) allow a local low-privileged user capable of loading BPF programs to corrupt kernel memory, with no public exploit identified at time of analysis and EPSS scoring exploitation likelihood at only 0.02%.

Use-after-free in the Linux kernel's ab8500 power supply driver (drivers/power/supply/ab8500) can be triggered during device removal or probe due to incorrect ordering of devm_-managed resource allocation. The race allows an IRQ handler to invoke power_supply_changed() against a freed or uninitialized power_supply handle, typically resulting in a kernel crash or silent memory corruption. No public exploit identified at time of analysis, EPSS is very low (0.02%), and the flaw is not on CISA KEV.

Memory corruption in the Linux kernel's pm8916_lbc power-supply driver (Qualcomm PM8916 PMIC linear battery charger) stems from a use-after-free in power_supply_changed(), where devm-managed teardown ordering lets a charger interrupt fire against a freed or not-yet-initialized power_supply handle during driver probe or removal. Local attackers able to trigger device unbind/rebind or module load/unload can crash the system or silently corrupt kernel memory. EPSS is very low (0.02%) and there is no public exploit identified at time of analysis; the issue is not in CISA KEV.

Use-after-free in the Linux kernel's goldfish power-supply driver (drivers/power/supply/goldfish_battery) allows a local attacker to crash the system or corrupt kernel memory by racing device probe/removal against the battery IRQ handler. The driver requested its IRQ via devm_ before registering the power_supply handle, so on teardown the handle is freed while the still-live interrupt can fire and call power_supply_changed() on freed (or, during probe, uninitialized) memory. No public exploit identified at time of analysis; EPSS is negligible (0.02%) and the bug is not in CISA KEV.

Use-after-free in the Linux kernel's OpenVPN data channel offload (ovpn) module allows a local attacker with low privileges to potentially trigger memory corruption when transmitting shared sk_buff packets through ovpn_net_xmit. The flaw stems from continued use of a stale skb pointer after skb_share_check frees the original buffer, affecting peer lookup, skb_dst_drop, and TX statistics paths. No public exploit identified at time of analysis, and the EPSS probability is very low (0.02%), suggesting the bug is more of a stability and memory-safety concern than an imminently weaponized vector.
