CVE-2026-7867
A local attacker with an active console session can exploit insufficient authorization checking on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A flaw was found in udisks2. A local attacker with an active console session can exploit insufficient authorization checking on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. This allows the attacker to spoof the 'as-user' parameter, mounting filesystems on behalf of arbitrary users, including privileged accounts. This can lead to local privilege escalation through mount point injection and manipulation of the mount namespace visible to privileged users.
