CVE-2026-89493

CVE-2026-89493 is an out-of-bounds read/write in the Linux kernel's OCFS2 filesystem module. The root cause is that ocfs2_validate_refcount_block() never validates rl_used and rl_count against the block's fixed on-disk capacity (247 records in a 4K block). A crafted or corrupted refcount block wi...
