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...

CVE-2026-80638

A flaw was found in the ocfs2 component of the Linux kernel. When a user unlinks a refcounted file whose refcount tree has leaf blocks, an out-of-bounds write occurs within the ocfs2removerefcountextent function. This happens because a memset operation writes past the intended memory boundary due...
