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...
