CVE-2026-72162

A flaw was found in ocfs2, a component of the Linux kernel. On-disk corruption of an inode's embedded extent list can lead to an array-index-out-of-bounds error. This occurs when the lnextfreerec value is zero or exceeds lcount during a write operation to the affected file. A local attacker with...

CVE-2026-72161
