A vulnerability in the Linux kernel's ocfs2 filesystem code allowed improper validation of refcount block metadata. Specifically, the rl_used field was not properly checked against rl_count and the block's capacity, enabling out-of-bounds memory access during refcount record processing. This could be triggered by mounting a crafted or corrupted ocfs2 image or by raw writes to the underlying block device. The issue was fixed by adding validation checks to reject malformed refcount blocks before processing. Join the discussion | GCVE Database | 09/11/2026, 21:31:29 UTC Added: 09/12/2026, 00:43:03 UTC |
