A security update for udisks2 addresses a local privilege escalation vulnerability identified as CVE-2026-7867. The issue arises from insufficient authorization checks on the 'as-user' option in the org.freedesktop.UDisks2.Filesystem.Mount() D-Bus method. This flaw could allow a local attacker to escalate privileges on affected systems. The vulnerability is rated as high severity by the vendor. Red Hat and SUSE have released patches to fix this issue in their respective distributions. The update is available for multiple architectures and versions of Red Hat Enterprise Linux 10 and SUSE versions prior to 10.2. No known exploits in the wild have been reported at this time.

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.
