CVE-2026-26103 unimportant priority: Debian including 1 source packages (udisks2), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
A flaw was found in the udisks storage management daemon that exposes a privileged D-Bus API for restoring LUKS encryption headers without proper authorization checks. The issue allows a local unprivileged user to instruct the root-owned udisks daemon to overwrite encryption metadata on block devices. This can permanently invalidate encryption keys and render encrypted volumes inaccessible. Successful exploitation results in a denial-of-service condition through irreversible data loss.
