CVE-2026-89492

A flaw was found in the Linux kernel's OCFS2 filesystem. A local attacker with the ability to mount a crafted on-disk image could exploit this vulnerability by providing excessive directory-index entry counts when reading metadata. This can lead to an out-of-bounds read, potentially causing...
