CVE-2025-8067: Udisks: out-of-bounds read in udisks daemon

A flaw was found in the Udisks daemon, where it allows unprivileged users to create loop devices using the D-BUS system. This is achieved via the loop device handler, which handles requests sent through the D-BUS interface. As two of the parameters of this handle, it receives the file descriptor list and index specifying the file where the loop device should be backed. The function itself validates the index value to ensure it isn't bigger than the maximum value allowed. However, it fails to validate the lower bound, allowing the index parameter to be a negative value. Under these circumstances, an attacker can cause the UDisks daemon to crash or perform a local privilege escalation by gaining access to files owned by privileged users.

Security readout for executives and security teams

CVE-2025-8067 is a local flaw in the UDisks daemon. An unprivileged local user may crash the daemon or gain limited access to privileged-owned files, creating denial-of-service and possible local privilege escalation risk on affected Linux systems. Exposure is most likely on Linux systems running affected udisks2 packages, especially listed Red Hat Enterprise Linux 7 ELS, 8, 9, 10, and related update streams. RHEL 6 status is unknown in the bundle. Local access to the host is required. Treat as high priority for multi-user Linux servers, workstations, and jump hosts. It is not a remote internet-facing bug, but it can matter wherever local users, shared access, or compromised low-privilege accounts exist. Mitigation focus: Apply relevant Red Hat errata updates for affected RHEL streams.; Review the Debian LTS advisory for Debian package guidance.; Inventory installed udisks or udisks2 versions across Linux hosts..
