Vulnerability from cvelistv5 – Published: 2026-07-29 16:14 – Updated: 2026-07-29 17:56

Title

fuse-overlayfs release-1.x preserves SUID/SGID bits after truncate/open(O_TRUNC)

Summary

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 open(O_TRUNC) and truncate handling on a copied-up file, allowing a low-privileged process to leave the upper-layer file with mode 4777. This issue is fixed in version 1.17.

Severity

Severity

Moderate

Scope

1 vulnerability in this advisory, including CVE-2026-52791.

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 O_TRUNC flag. This can enable a local attacker to manipulate file permissions, potentially leading to privilege escalation within the system.

4.7 (Medium)
