CVE-2026-31465

A flaw was found in the Linux kernel. This vulnerability occurs in the writeback mechanism, specifically when handling filesystems that do not guarantee data persistence on synchronization (sync) operations, such as fuse and fuse-overlayfs. Under certain conditions, like during a suspend-to-RAM event or if the fuse daemon is unresponsive, the kernel may improperly wait for flusher threads to complete writeback. This can lead to a system hang, resulting in a Denial of Service (DoS) for the affected system.
