CVE-2026-80644

A flaw was found in ocfs2, a component of the Linux kernel. A local attacker could exploit this vulnerability by providing a specially crafted OCFS2 image. When this fuzzed image is mounted, it can corrupt the journal dinode. This corruption leads to a kernel crash, resulting in a Denial of Servi...
