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.
