CVE-2026-31597

A flaw was found in the Linux kernel's OCFS2 Oracle Cluster File System version 2 component. A local attacker could exploit a use-after-free vulnerability when filemapfault drops the mmaplock before returning VMFAULTRETRY. This allows a concurrent munmap operation to free a vmareastruct, leading ...
