CVE-2026-26103
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk0th percentile - higher than 0% of all known CVEs
Summary
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.
Risk Assessment
Successful exploitation results in a denial-of-service condition through irreversible data loss, potentially crippling systems that store critical information on encrypted partitions.
Recommendation
Immediately update the udisks package to a patched version and restrict access to the D-Bus API for unprivileged users using D-Bus policies.
