CVE-2026-46095 Details
Description
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.
A vulnerability in the Linux kernel's md/md-llbitmap component has been addressed. The issue involved improper management of barrier operations before state machine transitions, which could lead to race conditions. The vulnerability has been fixed by ensuring that barrier operations are completed before any state transitions occur, preventing the state machine from advancing too quickly.
