Local privilege-adjacent memory corruption in the Linux kernel ublk (userspace block driver) subsystem allows a ublk server process to trigger use-after-free-style access on completed I/O requests by exiting while requests are still in flight. The regression, introduced by commit e63d2228ef83 which stopped decrementing the request reference count in __ublk_fail_req(), leaves a leaked UBLK_REFCOUNT_INIT reference that permits illegitimate user-copy and zero-copy operations on already-completed requests and trips WARN_ON_ONCE reference-count assertions during queue teardown. It carries a CVSS 7.8 (high) with local vector and low privileges, EPSS is negligible at 0.03% (7th percentile), and there is no public exploit identified at time of analysis.

Local privilege escalation and memory corruption in the Linux kernel FUSE subsystem's io-uring path allows an unprivileged local user to trigger list corruption and a resulting use-after-free. The flaw stems from a terminated-but-not-committed FUSE io-uring request never being unlinked from the queue's list, leaving a dangling entry that corrupts kernel memory. EPSS is very low (0.03%, 7th percentile) and there is no public exploit identified at time of analysis; a fix has been merged upstream and shipped by distributions such as Ubuntu.

CVE-2025-68793 Jan 13, 16:16 HIGH PATCH This Week

Local privilege escalation or kernel memory disclosure in the Linux kernel's amdgpu DRM driver stems from a use-after-free during GPU recovery, where a race between the scheduler timeout callback (drm_sched_job_timedout) and the TDR work queue can free a job structure before amdgpu_device_gpu_recover reads its pasid field. Affected systems are those running vulnerable kernels with AMD GPUs using the amdgpu driver; a local attacker able to submit GPU work and induce a GPU hang could trigger the freed-memory access, as demonstrated by the supplied KASAN slab-use-after-free trace. There is no public exploit identified at time of analysis, and the EPSS score is negligible (0.03%, 7th percentile), consistent with a difficult-to-win kernel race rather than a broadly exploited flaw.

CVE-2025-68774 Jan 13, 16:15 HIGH PATCH This Week

Denial of service in the Linux kernel's HFS+ (hfsplus) filesystem driver allows a local user with access to a mounted HFS+ volume to crash the kernel via a reference-counting race in __hfs_bnode_create(). When sync() and link() operations run concurrently, two threads can both attempt to create the same B-tree node; the thread that loses the race reuses the already-hashed node without incrementing its refcount, so a later put trips BUG_ON(!atomic_read(&node->refcnt)) and panics the system. No public exploit has been identified at time of analysis, EPSS risk is very low (0.05%), and the issue is not in CISA KEV.
