About this tag
CVE-2026-64187 is a Linux kernel vulnerability that can cause mount-time kernel crashes when XFS recovery processes a malformed journal. The flaw involves a NULL pointer dereference triggered by a crafted or corrupted log containing a committed transaction item with no data regions, leading to a denial-of-service condition during filesystem mount. The issue does not arise from normal XFS activity, and the upstream fix is small but important for preventing system instability. This tag covers discussions about the vulnerability, its impact on XFS filesystems, and the patch that addresses the crash, relevant for Linux administrators and IT professionals managing affected systems.
