CVE-2023-54032

CVE-2023-54032 affects the Linux kernel’s btrfs quota handling. The root cause is a race in deleting a quota root from the dirty_cowonly_roots list without acquiring trans_lock, which can race with concurrent list manipulation (e.g., add_root_to_dirty_list). This unsynchronized access may trigger...

In the Linux kernel, the following vulnerability has been resolved: hwrng: virtio - Fix race on dataavail and actual data The virtio rng device kicks off a new entropy request whenever the data available reaches zero. When a new request occurs at the end of a read operation, that is, when the...

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-2025-68732

The CVE-2025-68732 entry refers to a Linux kernel vulnerability fixed in the gpu: host1x subsystem. The root cause was a race between host1x_syncpt_alloc() and host1x_syncpt_put(), mitigated by switching to kref_put_mutex() so the refcount drop to zero cannot race with syncpt_release acquiring th...
