CVE-2026-64265

A flaw was found in the Linux kernel's fuse component. When a fuse request is interrupted and then resent, a specific interrupt entry intrentry is not properly cleared. If the requesting task subsequently receives a fatal signal, this uncleared entry can lead to a use-after-free condition. This...

CVE-2026-53388

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. The fusetrymovefolio function, responsible for managing page cache folios, fails to re-lock a request after initially unlocking it on a successful path. This oversight allows another function, fusechanabort, to...

CVE-2026-53167

A flaw was found in the Linux kernel's FUSE Filesystem in Userspace component.

When using synchronous initialization sync init, if the FUSE server exits unexpectedly while processing the FUSEINIT request, the filesystem creation process can hang. This issue occurs because the mounting thread keep...

CVE-2026-31694

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. A malicious FUSE server could exploit this by providing an oversized directory entry dirent that is not properly validated. This improper validation causes a memory copy operation to write beyond the allocated buffer,...
