CVE-2023-54041

In the Linux kernel, the following vulnerability has been resolved: iouring: fix memory leak when removing provided buffers When removing provided buffers, iobuffer structs are not being disposed of, leading to a memory leak. They can't be freed individually, because they are allocated in...

UBUNTU-CVE-2023-54033

In the Linux kernel, the following vulnerability has been resolved: bpf: fix a memory leak in the LRU and LRUPERCPU hash maps The LRU and LRUPERCPU maps allocate a new element on update before locking the target hash table bucket. Right after that the maps try to lock the bucket. If this fails,...

UBUNTU-CVE-2023-54013

In the Linux kernel, the following vulnerability has been resolved: interconnect: Fix locking for runpm vs reclaim For cases where iccbwset can be called in callbaths that could deadlock against shrinker/reclaim, such as runpm resume, we need to decouple the icc locking. Introduce a new iccbwlock...

UBUNTU-CVE-2023-54032

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race when deleting quota root from the dirty cow roots list When disabling quotas we are deleting the quota root from the list fsinfo-dirtycowonlyroots without taking the lock that protects it, which is struct...

UBUNTU-CVE-2025-68358

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix racy bitfield write in btrfsclearspaceinfofull From the memory-barriers.txt document regarding memory barrier ordering guarantees: These guarantees do not apply to bitfields, because compilers often generate code to...

CVE-2023-54013

CVE-2023-54013 concerns the Linux kernel where interconnect locking could deadlock between runpm and memory reclaim. The description notes a fix to decouple ICC locking by introducing a new icc_bw_lock to serialize bandwidth aggregation, separating it from paths that allocate memory (e.g., node/l...

CVE-2025-68732

In the Linux kernel, the following vulnerability has been resolved: gpu: host1x: Fix race in syncpt alloc/free Fix race condition between host1xsyncptalloc and host1xsyncptput by using krefputmutex instead of krefput + manual mutex locking. This ensures no thread can acquire the syncptmutex after...

CVE-2025-68371

CVE-2025-68371 relates to the Linux kernel SCSI smartpqi driver. A race between the abort handler that schedules a LUN reset and device removal via sdev_destroy() could cause the LUN reset to run after the device was removed, leading to use‑after‑free and access to freed resources. The fix, as do...

CVE-2025-68358

CVE-2025-68358 (Linux kernel, btrfs) : A race condition was fixed in btrfs_clear_space_info_full() that updated bitfield members (full, chunk_alloc, flush) without holding the space_info lock, risking corruption of adjacent fields due to non-atomic read-modify-write sequences on bitfields. The fi...
