Summary
udisks2 vulnerability
Details

It was discovered that UDisks did not correctly validate the caller identity when handling the as-user option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. A local attacker with an active console session could possibly use this issue to mount filesystems on behalf of arbitrary users, including privileged accounts, leading to local privilege escalation.
