CVE-2025-21942

CVE-2025-21942 affects the Linux kernel btrfs zoned code. A hang can occur in cow_file_range() when unlocking extents if there is no active zone finish path or after partial allocations, due to unlock code being moved outside the loop by a commit. The fix sets the end to the end of the allocated ...
