Package : udisks2 CVE ID : CVE-2026-7867

The following vulnerability has been discovered in the UDisks storage daemon:

CVE-2026-7867

Azizcan Dastan and Ozlem Ozan discovered a local privilege escalation vulnerability in udisks2 involving the Filesystem.Mount D-Bus method. Using the 'as-user' option, an unprivileged local user can in some cases influence the mount execution path so that a filesystem mount is performed in a privileged/root context without the expected PolicyKit authorization behavior.

For the stable distribution (trixie), this problem has been fixed in version 2.10.1-12.1+deb13u2.

We recommend that you upgrade your udisks2 packages.

For the detailed security status of udisks2 please refer to its security tracker page at:
