Use-after-free in the Linux kernel's idmouse USB fingerprint driver allows a low-privileged local attacker to corrupt kernel memory by racing a device disconnect against a file-descriptor release, potentially enabling local privilege escalation to root. The bug stems from `mutex_unlock()` accessing the freed driver-data structure after the lock is released, a documented non-atomic behavior; the fix introduces a `kref` reference counter to correctly manage object lifetime. Patches are available across all active stable branches; no active exploitation or public exploit has been reported.
Use-after-free in the Linux kernel's USB ldusb driver allows a local unprivileged user to corrupt kernel memory by racing disconnect() against release() on a connected USB device. The root cause is that mutex_unlock() is documented as non-atomic and may access the mutex object after it logically releases the lock, creating a window where the driver data structure can be freed while still in use. No public exploit has been identified at time of analysis, and EPSS is low (0.22%), but the C:H/I:H/A:H CVSS impact vector reflects the potential for full kernel privilege escalation if successfully triggered.
Use-after-free in the Linux kernel's USB iowarrior driver exposes systems with Code Mercantile IO-Warrior USB devices to kernel memory corruption, potentially enabling local privilege escalation to root. The defect exists because submitted write URBs are not cancelled during close(), leaving them in-flight at disconnect time; the completion handler then fires against already-freed device structures. No public exploit code has been identified at time of analysis, and EPSS at 0.22% (13th percentile) reflects minimal observed exploitation pressure, though the C:H/I:H/A:H CVSS impact reflects genuine kernel-level consequence.
The Linux kernel's legousbtower USB driver contains a use-after-free race condition between the release() and disconnect() code paths, present since Linux 2.6.25. An authenticated local user with a LEGO USB Tower device attached can trigger the race at disconnect time to corrupt freed kernel memory, potentially gaining elevated privileges or crashing the system. Patches have been issued across all active stable branches (5.10, 5.15, 6.1, 6.6, 6.12, 6.18, 7.1); no public exploit code or CISA KEV listing exists at time of analysis.
Local privilege escalation in the Linux kernel's digi_acceleport USB serial driver allows authenticated local users to corrupt kernel memory and execute arbitrary code as root. The vulnerability arises from a race condition in the digi_write_inb_command() function that mishandles timeouts and incorrectly updates transfer buffers, leading to write buffer corruption. No active exploitation has been reported, and publicly available exploit code has not been identified; a vendor patch is available across multiple stable kernel branches.
Out-of-bounds array read in the Linux kernel's USB Type-C Port Manager (TCPM) svdm_consume_modes() function allows a physically connected malicious USB-C partner device to read kernel memory beyond the svids[] array boundary and force registration of an arbitrary, attacker-chosen SVID via typec_partner_register_altmode(). The vulnerability arises because pmdata->svid_index - which is incremented in response to partner-supplied SVDM messages - is never validated against SVID_DISCOVERY_MAX (16) before indexing pmdata->svids[]. Patches are confirmed available across eight stable kernel branches (5.10 through 7.2-rc3); no public exploit or CISA KEV listing exists at time of analysis.
Use-after-free in the Linux kernel's USB Type-C UCSI CCG driver allows a local attacker with low privileges to corrupt kernel memory, potentially achieving arbitrary kernel code execution. The flaw exists in the module teardown path of the Cypress CCG UCSI driver: ucsi_ccg_remove() calls ucsi_destroy() - which kfree()s the ucsi object - before calling free_irq(), leaving a window in which the threaded IRQ handler ccg_irq_handler() can access the freed ucsi struct via ucsi_notify_common(). No public exploit code exists and the bug was discovered by static analysis; EPSS is 0.22% (13th percentile), reflecting no observed in-the-wild activity.
Out-of-bounds read and write in the Linux kernel's UDF filesystem driver allows a local attacker with the ability to mount a crafted UDF image to escalate privileges to root. The vulnerability stems from the sparing table length being validated as a byte count but consumed as an entry count, leading to memory corruption. No active exploitation (KEV) or public proof-of-concept is currently known, and EPSS estimates a 0.22% chance of exploitation in the next 30 days.
Out-of-bounds write in the Linux kernel Intel QAT (Quick Assist Technology) RSA CRT driver corrupts kernel DMA memory when a local attacker supplies an RSA private key with CRT components larger than half the modulus size. The QAT driver's qat_rsa_setkey_crt() allocates DMA buffers at key_sz/2 but the right-alignment expression `dst + half_key_sz - len` wraps on unsigned underflow when len > half_key_sz, directing memcpy to write attacker-controlled bytes past the DMA allocation. No public exploit code exists at time of analysis; EPSS is 0.22% and the bug has been present since Linux 4.8 across all maintained stable branches.
Out-of-bounds read and write in the Linux kernel exFAT filesystem driver's `exfat_find_dir_entry()` allows a local attacker with low privileges to corrupt kernel heap memory or read adjacent kernel data by mounting or triggering access to a crafted exFAT filesystem image. The bug arises because the `uniname` output pointer advances by a fixed stride of `EXFAT_FILE_NAME_LEN` (15 code units) per TYPE_EXTEND directory entry regardless of actual content length, while the loop guard only checks accumulated `name_len` — a discrepancy a malicious image can exploit indefinitely. No public exploit code and no CISA KEV listing exist at time of analysis; EPSS is 0.22%.
Out-of-bounds read and write in the Linux kernel's synaptics-rmi4 F3A GPIO driver allows local low-privileged users to leak adjacent kernel slab memory to userspace or perform a controlled heap write via the evdev ioctl interface. The root cause is a size mismatch: gpio_key_map is allocated for at most 6 entries while input->keycodemax is set to the full device-reported gpio_count (up to 127), causing the input core's EVIOCGKEYCODE and EVIOCSKEYCODE ioctls to index past the allocation. No public exploit has been identified at time of analysis; EPSS is 0.22%.
Out-of-bounds read and write in the Linux kernel synaptics-rmi4 input driver allows a local attacker with low privileges to gain full root access by exploiting a bound-check flaw in the F30 GPIO/LED interrupt handler. Affects kernels where gpioled_count exceeds 6 and GPIO support is enabled, leading to memory corruption through the EVIOCGKEYCODE/EVIOCSKEYCODE ioctls. No known active exploitation, no public exploit code, and EPSS risk is very low (0.22%).
Stack out-of-bounds write in the Linux kernel Goodix touchscreen driver allows kernel stack memory corruption through a malicious, counterfeit, or physically tampered Goodix I2C touchscreen controller that advertises more than the supported maximum of 10 contact points. All Linux kernel versions from 4.1 through the pre-patch stable series are affected on systems equipped with Goodix GT-series touchscreen hardware; patched releases are available across all active stable branches. No public exploit code exists and no active exploitation has been reported (absent from CISA KEV), with EPSS placing exploitation probability at 0.22%.
Out-of-bounds heap write in the Linux kernel iforce force-feedback input driver allows a physically connected malicious device to corrupt kernel memory. The iforce driver's status packet handler blindly uses a device-supplied effect index masked only to 0-127 as an array subscript into a 32-entry array, enabling `test_and_set_bit`/`test_and_clear_bit` operations up to 95 entries past the array boundary and into trailing kzalloc'd structure members. No confirmed active exploitation exists (not in CISA KEV), and EPSS probability is very low at 0.22% (13th percentile), but successful exploitation against an unpatched kernel yields high confidentiality, integrity, and availability impact at the kernel heap level.
Heap out-of-bounds write in the Linux kernel's touchwin serial touchscreen driver allows a malicious, malfunctioning, or counterfeit Touchwindow peripheral to corrupt kernel heap memory one attacker-chosen byte at a time, potentially enabling local privilege escalation or kernel crash. The flaw exists since Linux 2.6.19 and affects all stable branches through 7.1.3 and pre-7.2-rc1; patched versions have been released across six stable series (5.10.261, 5.15.212, 6.1.178, 6.6.145, 6.12.96, 6.18.39, 7.1.4). EPSS is 0.22% (13th percentile) and no public exploit or CISA KEV listing has been identified, reflecting the niche hardware prerequisite that sharply limits real-world exposure.
A use-after-free in the FUSE subsystem of the Linux kernel allows a local attacker with permission to mount a FUSE filesystem to escalate privileges or crash the system. The vulnerability exists in fuse_ref_folio() due to improper request locking, and affects kernel versions from 2.6.35 through unpatched longterm branches. Patches are available, and no active exploitation or public exploit code has been identified.
Local privilege escalation in Linux kernel's vme_user staging driver via an out-of-bounds write in slave read/write helpers. A local attacker can overflow the fixed-size kern_buf when the VME window exceeds 128 KiB, leading to arbitrary code execution. No active exploitation or public exploit is known, but the vulnerability has been confirmed dynamically with KASAN; EPSS indicates low exploitation probability.
Heap-based out-of-bounds write in the Linux kernel's ntfs3 filesystem driver during journal replay allows local attackers to achieve kernel code execution by mounting a malicious NTFS image. The vulnerability exists because log_replay() does not validate Dirty Page Table capacity against attacker-controlled fields, leading to a slab corruption. No active exploitation or public exploit code has been identified, and the attack requires user interaction to mount a crafted filesystem.
Local privilege escalation in the Linux kernel's SMB client witness notification handler allows a low-privileged attacker to exploit a use-after-free condition. Affected are Linux kernel versions 5.11 and later that have the CIFS witness feature enabled. Successful exploitation can lead to arbitrary code execution with elevated privileges, fully compromising the system.
The Linux kernel writeback subsystem crashes with a use-after-free during container exit due to a race between cgroup_writeback_umount() and inode_switch_wbs(). An in-flight writeback-context switch can pass the SB_ACTIVE check and take an inode reference before the filesystem unmount clears SB_ACTIVE, but delay queuing its work item - causing the umount path to flush a workqueue that has nothing pending, destroy percpu counters via put_super(), and then have the deferred switch work invoke percpu_counter_dec() on freed memory, triggering a BUG_ON or silent UAF. No public exploit is identified at time of analysis; EPSS stands at 0.21% (12th percentile) with no CISA KEV listing.
Use-After-Free in the Linux kernel HID letsketch driver allows local exploitation during device unbind, potentially enabling kernel memory corruption and privilege escalation on affected systems. The letsketch_probe() function arms a per-device kernel timer (inrange_timer) with a 100 ms timeout, but no .remove callback exists to drain the timer before devm cleanup frees letsketch_data and input_dev structures on USB unplug or rmmod, producing a UAF read/write into freed kernel memory. Patches are backported across six stable kernel branches; no public exploit code exists and EPSS is 0.21% (12th percentile), reflecting the niche device requirement and race-condition complexity.
Incorrect RCU lock annotations in the Linux kernel's BPF LPM trie map implementation (`kernel/bpf/lpm_trie.c`) cause lockdep false positives on debug kernels when sleepable BPF programs access `BPF_MAP_TYPE_LPM_TRIE` maps via lookup, update, or delete operations. The mismatch arises because sleepable BPF programs hold `rcu_read_lock_trace()` while the trie code asserts `rcu_read_lock_bh_held()` or `rcu_read_lock_held()`, producing repeated 'suspicious RCU usage' kernel warnings per distinct callsite. The Linux kernel developers explicitly state no actual use-after-free occurs, since Tasks Trace RCU already serializes against trie node reclaim; however, the incorrect annotation undermines lockdep's ability to detect future regressions and is increasingly impactful as sleepable BPF LSM programs become common in production security tooling. No public exploit exists and no CISA KEV listing has been issued.
Use-after-free and memory leak in the Linux kernel's EHCI and FOTG210 USB isochronous submit paths expose systems running kernel versions from 2.6.15 through 7.1.3 to local kernel memory corruption by a low-privileged user. When an isochronous URB submission fails before the staged schedule handoff - either because the host controller becomes inaccessible or usb_hcd_link_urb_to_ep() returns an error - the ehci_iso_sched allocation is not freed and urb->hcpriv retains a dangling pointer, creating a UAF condition. No public exploit exists and the EPSS score is 0.21% (12th percentile), but vendor-released patches across multiple stable branches are available and should be applied to eliminate the risk.
Use-after-free in the Linux kernel USB gadget UDC subsystem exposes systems with DWC3-based USB controllers to a race condition between usb_del_gadget() and gadget_match_driver(), enabling a NULL pointer dereference that can crash the kernel or enable privilege escalation on unpatched systems. The flaw affects all major Linux stable branches from 5.15.x through 7.1.x prior to the patched releases, and is particularly relevant for embedded Linux, Android-based devices, and IoT hardware that use USB gadget/device mode. No public exploit has been identified at time of analysis, and EPSS remains at 0.21% (12th percentile), reflecting current low exploitation interest.
Local privilege escalation in the Linux kernel's I2C subsystem allows a low-privileged local attacker to compromise system integrity, confidentiality, and availability via a race condition during I2C adapter deregistration. The vulnerability affects kernel versions from 2.6.31 up to unpatched releases, with fixes available in stable trees 5.15.212, 6.1.178, 6.6.145, 6.12.96, 6.18.39, 7.1.4, and 7.2-rc1. No public exploit code or active exploitation is currently reported, and EPSS indicates a low exploitation probability (0.21%).
Local denial of service in the Linux kernel UDF filesystem allows an unprivileged local user to panic the system by truncating a file on a crafted UDF media. On desktop systems where polkit permits unprivileged mounting of removable media, an attacker can trigger this reliably. The vulnerability has public patches with exact fixed versions and a low EPSS exploitation probability (0.21%).
Local privilege escalation in the Linux kernel’s cs35l41_hda audio driver allows a low-privileged user to corrupt kernel memory and execute arbitrary code. The flaw arises when firmware autostart is disabled and a firmware load work item is queued, then
Elevation of privilege in the Linux kernel's tcpci_rt1711h USB Type-C port controller driver allows a local attacker with low privileges to potentially achieve full system compromise. The driver fails to unregister the TCPCI port when an interrupt request or alert enable step fails during device probe, leaving a stale resource that can be exploited for code execution. No active exploitation or public exploit code is known; EPSS probability is low (0.21%).
Use-after-free in the Linux kernel Bluetooth MGMT subsystem allows a local attacker with low privileges to trigger kernel memory corruption via a race condition between add_device and remove_device operations. The flaw exists in add_device_complete(), which dereferences a hci_conn_params pointer without holding hci_dev_lock, while a concurrent MGMT_OP_REMOVE_DEVICE path frees the same object under that lock. KASAN confirms exploitation as slab-use-after-free; no public exploit or active exploitation (CISA KEV) has been identified, and patches have been released across multiple stable branches.
Use-after-free memory corruption in the Linux kernel's netpoll subsystem allows a local attacker or concurrent kernel path to access freed memory during the netpoll shutdown sequence. The flaw exists because cancel_delayed_work() - called from softirq context during __netpoll_cleanup() - does not block until the TX worker finishes, permitting queue_process() to dereference a kfree'd npinfo struct via container_of(). KASAN confirms the UAF; patches are available across multiple stable kernel branches, and no public exploit or KEV listing exists at time of analysis.
Use-after-free memory corruption in the Linux kernel's NXP i.MX8 ISI (Image Sensing Interface) media driver is triggered during module removal (rmmod of imx8_isi), confirmed by KASAN slab-use-after-free reports. The root cause is an incorrect teardown order in mxc_isi_remove(): the crossbar cleanup frees media entity pads before the V4L2 cleanup has finished removing media links that reference those same pads, resulting in a dangling pointer dereference in __media_entity_remove_link(). No public exploit has been identified at time of analysis, and with EPSS at 0.21% (11th percentile), real-world weaponization appears unlikely despite the CVSS 7.8 score.
A race condition in the Linux kernel's shrinker subsystem can cause use-after-free or double-free memory errors during memory cgroup creation and teardown. Local attackers with low privileges may exploit this to escalate privileges to kernel level, leading to full system compromise (confidentiality, integrity, and availability impact). Patches are available in multiple stable kernel branches; no active exploitation is reported (CISA KEV not listed), and the EPSS exploitation probability is low (0.21%).
Out-of-bounds write in the Linux kernel's CoreSight ultrasoc-smb driver when used as a perf AUX sink allows a local attacker to elevate privileges. The vulnerability arises from improper page index normalization in smb_sync_perf_buffer(), leading to a heap buffer overflow. Although no active exploitation or public proof-of-concept is known, the weakness has been patched upstream and carries an EPSS score of 0.21%.
Double-free memory corruption in the Linux kernel's Qualcomm CPU frequency hardware driver (qcom-cpufreq-hw) allows a local low-privileged attacker on Qualcomm SoC-based systems to trigger kernel heap corruption, potentially escalating privileges to root. The flaw originates in qcom_cpufreq_hw_cpu_exit(), which incorrectly calls kfree() on memory allocated via devm_kzalloc() - memory already tracked by the kernel's device resource management (devres) system. This results in a double-free when the platform device is subsequently detached and devres performs its own cleanup. No public exploit code exists and EPSS is low (0.21%), consistent with a static-analysis discovery rather than active exploitation.
Arbitrary code execution in the Linux kernel's BPF BTF parser allows local privilege escalation. Malformed BTF data can cause an integer overflow in the repeated field count calculation, bypassing a capacity check and leading to a heap buffer overflow. With low EPSS score (0.21%), widespread exploitation is currently unlikely, but unprivileged local users who can load BPF programs are at risk of complete system compromise.
Use-after-free and list corruption in the Linux kernel's Intel QuickAssist Technology (QAT) crypto driver allows a local low-privileged attacker to trigger kernel memory corruption by racing concurrent service registration and device lifecycle operations. The crypto/qat subsystem's service_table linked list is guarded by service_lock only during insertions and deletions, but seven device-state functions iterate the list unprotected, enabling a concurrent adf_service_register() or adf_service_unregister() call to mutate the list mid-traversal. Exploiting this race can result in kernel crash, arbitrary kernel memory read, or local privilege escalation to root. No public exploit code has been identified and EPSS stands at 0.21% (11th percentile), but the impact class is high for systems running QAT-capable Intel hardware.
Touch event indexing in the Linux kernel mms114 driver misaligns reads for MMS134S and MMS136 controllers, which pack events at 6-byte intervals while the driver iterates at 8-byte struct offsets. On systems physically equipped with these MELFAS touch controllers, a locally privileged attacker can trigger multi-touch input processing that causes the driver to read kernel memory from incorrect offsets, potentially exposing sensitive data or corrupting kernel state. No public exploit or active exploitation has been identified; EPSS stands at 0.21%, reflecting negligible widespread exploitation risk at time of analysis.
Stack out-of-bounds write in the Linux kernel's mms114 touchscreen driver allows a physically-positioned attacker with access to the I2C bus - or the ability to substitute a malicious or counterfeit controller - to overwrite the IRQ-thread stack, corrupting the stack canary, saved registers, and return address for potential kernel-level code execution. Affected systems include Linux kernel builds from version 3.6 onward that load the mms114 driver on hardware incorporating the Melfas MMS114 touchscreen controller. No public exploit code has been identified at time of analysis, and EPSS places exploitation probability at just 0.21%, consistent with the narrow hardware-specific attack surface.
Local privilege escalation in the Linux kernel FUSE subsystem allows a low-privileged attacker to corrupt kernel memory
Heap corruption in the Linux kernel's IIO ad_sigma_delta driver allows a local attacker with low privileges to overflow the kernel heap, potentially achieving privilege escalation or causing denial of service. The flaw stems from improper handling of registerless sigma‑delta ADC devices when no ready GPIO is assigned and the reset clock count is zero. EPSS modelling indicates low exploitation likelihood (0.21%), and no active exploitation is reported; patches are available from the vendor.
The user asks for a comprehensive JSON analysis of CVE-2026-64485. I need to synthesize data from the provided sources. Let's examine the input carefully. CVE ID: CVE-2026-64485 Description: In the Linux kernel, ALSA: compress: Fix task creation error unwind. It details a resource leak when snd_compr_task_new() allocates driver task, and if subsequent steps fail, task_free() callback is not called, leaking driver resources. Also, an error in file descriptor allocation may not be reported correctly, leading to incorrect success reporting. CVSS: 7.8, AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H CWE: N/A EPSS: 0.21% (11th percentile) Patch: Available from vendor Reported by: Linux CPE: cpe:2.3:a:linux:linux:*:*:*:*:*:*:*:* Tags: Information Disclosure, Linux ENISA EUVD ID: EUVD-2026-48829 Affected versions (EUVD): a list of commit hashes and kernel versions. The patch refs are three git.kernel.org links. Now, I need to generate all fields as plain text strings. I'll go through each field requirement. product_name: "Linux kernel" (or "Linux Kernel"? The requirement: 1-3 words ONLY. The CVE is in the Linux kernel, specifically the ALSA compress subsystem. So "Linux Kernel" is appropriate. summary: Must be an original synthesis, 2-3 sentences. Not copying description. Start with specific impact verb and product. So: "Local privilege escalation in the Linux kernel's ALSA compress driver subsystem allows a local authenticated attacker to trigger a resource leak and potentially escalate privileges due to improper cleanup when creating an audio compress task. The vulnerability affects Linux kernels with the snd-compress module (versions as specified), and can lead to memory leaks and denial of service or arbitrary code execution. Although no public exploit is identified at time of analysis, the issue is addressed in upstream patches." I'll incorporate that the vulnerability leads to resource leak and eventually could lead to other issues. But the description doesn't explicitly men
Use-after-free in the Linux kernel's usbio (USB I/O bridge) driver allows a local, low-privileged attacker to corrupt kernel slab memory during USB device disconnect, potentially achieving privilege escalation or triggering a kernel panic. The bug lies in usbio_disconnect(), which iterates the client list in reverse using list_for_each_entry_reverse() - a macro that reads client->link.prev after the loop body, but auxiliary_device_uninit() can free the current client before that read, dereferencing freed slab memory. Patches are confirmed in Linux stable branches 6.18.39, 7.1.4, and 7.2-rc3; no public exploit or active exploitation is identified at time of analysis.
Double-free and use-after-free memory corruption flaws in the Linux kernel's staging Intel IPU7 media driver allow a local low-privileged user to corrupt kernel heap memory during driver initialization error paths. Two functions - ipu7_isys_init() and ipu7_psys_init() - incorrectly call kfree(pdata) after device teardown has already freed the same allocation via the ipu7_bus_release() reference-count path, producing a CWE-415 double-free. A concurrent use-after-free also occurs when ERR_CAST() dereferences the already-freed adev pointer before the function returns. No public exploit code exists and exploitation probability is low (EPSS 0.21%), but the C:H/I:H/A:H impact reflects the theoretical kernel code execution or crash potential.
Use-after-free in the Linux kernel USB iowarrior driver allows a local unprivileged user to corrupt kernel memory when a USB device disconnect races with a file release operation. The root cause is that mutex_unlock() is documented as non-atomic and may access the mutex structure after releasing the lock, meaning the driver data object can be freed while mutex_unlock() is still executing. An attacker who can trigger the race - by opening the iowarrior device and simultaneously provoking a USB disconnect - may achieve kernel memory corruption leading to privilege escalation. No public exploit code exists and EPSS is low (0.21%), but the impact class is standard kernel UAF.
Use-after-free and missing forward security in the loongson-rng crypto driver of the Linux kernel allow a local, low-privilege attacker to corrupt memory and potentially execute arbitrary code, compromise system integrity, or read sensitive information. Affected systems are primarily Loongson-based machines running kernels between v6.18 and the respective fix versions; the driver itself is unused by any in‑kernel consumer and is being removed entirely rather than patched. No active exploitation or public exploit code is known, and the EPSS exploitation probability is low (0.21%).
Page use-after-free in the Linux kernel perf/aux subsystem allows a local authenticated attacker to read or write freed kernel memory, potentially achieving privilege escalation. The flaw arises because map_range() accesses rb->aux_pages[], rb->aux_nr_pages, and rb->aux_pgoff while holding only the per-event mmap_mutex, whereas those fields are serialised by the ring-buffer-level rb->aux_mutex; two events sharing one ring buffer via PERF_EVENT_IOC_SET_OUTPUT can therefore race rb_alloc_aux() against map_range(), leaving a VM_PFNMAP mapping pointing to a freed physical frame. No public exploit has been identified at time of analysis, and EPSS exploitation probability is very low at 0.21% (11th percentile).
We are tasked to synthesize a comprehensive analysis for CVE-2026-64293. Need to output JSON. Given data: - CVE ID: CVE-2026-64293 - Description: long description about iommufd veventq read bug with sizeof(hdr) vs sizeof(*hdr).

Local privilege escalation in the Linux kernel's fuse-uring subsystem allows a local attacker to trigger a use-after-free condition by racing with the async stop queues function, potentially resulting in arbitrary code execution and complete system compromise. The vulnerability affects Linux kernel versions 6.14 through 6.18.x (patched in 6.18.39, 7.1.4,
A race condition in the Linux kernel's fuse-uring subsystem allows a local user to achieve privilege escalation and full system compromise. The vulnerability, triggered by concurrent operations on the queue->stopped flag outside of locking, leads to a use-after
Use-after-free in the Linux kernel’s fuse-uring subsystem allows a local authenticated attacker to escalate privileges. The race condition occurs when a malicious userspace sends a commit SQE before the kernel completes the memcpy of request data, triggering a freed fuse_req to be reused. CVSS base score is 7.8 but EPSS probability is low (0.21%), and no public exploit or active exploitation has been reported.
