Description OSIDB Bzimport 2026-05-27 15:10:04 UTC
In the Linux kernel, the following vulnerability has been resolved:

md/md-llbitmap: raise barrier before state machine transition

Move the barrier raise operation before calling llbitmap_state_machine()
in both llbitmap_start_write() and llbitmap_start_discard(). This
ensures the barrier is in place before any state transitions occur,
preventing potential race conditions where the state machine could
complete before the barrier is properly raised.
