Threats Tagged 'cve-2026-26104'

The Udisks project provides a daemon, tools, and libraries to access and manipulate disks, storage devices, and technologies. Security Fix(es): * udisks: Missing Authorization Check Allows Unprivileged Users to Back Up LUKS Headers via udisks D-Bus API (CVE-2026-26104) * udisks: Missing Authorization Check Allows Unprivileged Users to Restore LUKS Headers via udisks D-Bus API (CVE-2026-26103) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

A flaw was found in the udisks storage management daemon that allows unprivileged users to back up LUKS encryption headers without authorization. The issue occurs because a privileged D-Bus method responsible for exporting encryption metadata does not perform a policy check. As a result, sensitive cryptographic metadata can be read and written to attacker-controlled locations. This weakens the confidentiality guarantees of encrypted storage volumes.

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.
