SUSE CVE-2026-52791

fuse-overlayfs is an implementation of overlayfs in FUSE for rootless containers. Prior to 1.17, the release-1.x C branch preserves SUID and SGID mode bits in main.c during openOTRUNC and truncate handling on a copied-up file, allowing a low-privileged process to leave the upper-layer file with...

Fedora 44 : fuse-overlayfs (2026-4e0490640f)

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-4e0490640f advisory. Update to fuse-overlayfs 1.17 to fix CVE-2026-52791: privilege escalation via SUID/SGID bit preservation on file truncation. When a file with SUID/SGID bits ...

CVE-2026-52791

A flaw was found in fuse-overlayfs, a component used for rootless containers. This vulnerability allows a low-privileged process to retain SUID Set User ID and SGID Set Group ID permissions on files after they are truncated or opened with the OTRUNC flag. This can enable a local attacker to...

CVE-2026-64266

A flaw was found in the Linux kernel's FUSE Filesystem in Userspace component. The fusereffolio function does not properly re-lock a request after unlocking it, which can lead to a use-after-free vulnerability. A local attacker could exploit this flaw to potentially execute arbitrary code or caus...

CVE-2026-64258

A flaw was found in the fuse-uring component of the Linux kernel. When a copy operation to the userspace ring buffer fails, a request can be terminated improperly, leading to a NULL pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial...

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...
