CVE-2026-64267

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. On 32-bit systems, an integer overflow vulnerability exists in the handling of FUSENOTIFYPRUNE messages. A malicious FUSE daemon or a local user could craft a prune notification with a specific count, causing an intege...

CVE-2026-64267

CVE-2026-64267 affects the Linux kernel’s FUSE (Filesystem in Userspace) path. The issue is an integer overflow in handling FUSE_NOTIFY_PRUNE messages on 32-bit architectures, where the product of outarg.count and sizeof(u64) can wrap during payload length validation, potentially causing the kern...
