Hi,
The following vulnerability was published for gvfs.
CVE-2026-88924[0]:
| A flaw was found in the admin backend of gvfs. The privileged gvfsd-
| admin daemon changes the ownership of newly created private D-Bus
| sockets by calling the link-following chown() function on a pathname
| inside a user-controlled directory. A local attacker can exploit
| this via a Time-of-Check Time-of-Use (TOCTOU) race condition and
| exchange the socket pathname with a symbolic link pointing to an
| arbitrary root-owned file (such as /etc/pam.d/su). The daemon
| subsequently follows the symlink and changes the ownership of the
| targeted root-owned file to the attacker's user ID. This allows an
| authenticated local attacker to modify critical system files,
| leading to a full local privilege escalation to root.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
