Hi Christoph,

The following vulnerability was published for luksmeta.

CVE-2026-107565[0]:
| 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.

At time there was only the Red Hat bugzilla, I filled a upstream issue
to ask more in [2].


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
