Published Oct 8, 2026 CVSS 3.1 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
A flaw was found in luksmeta. A local attacker with administrative privileges can cause data corruption when saving metadata to a Linux Unified Key Setup (LUKS) device. Due to incorrect boundary calculations and flawed overlap detection, new metadata entries can be written beyond available free space or over existing records. This issue can corrupt stored encrypted payload data or existing metadata, potentially rendering the affected data inaccessible.
