CVE-2026-107565 Red Hat CVE debrief

Who should care

System administrators and security teams responsible for systems using luksmeta, especially in contexts where administrative privileges are involved, should assess exposure and prioritize remediation.

Why it matters

CVE-2026-107565 allows a local attacker with administrative privileges to cause data corruption in luksmeta. Assess exposure, prioritize remediation, and verify specific versions affected and remediation steps from official sources.

• Data corruption can occur when saving metadata to a LUKS device, potentially rendering affected data inaccessible.
• Administrative privileges are required to exploit this flaw, indicating a need for strict access controls.
• Remediation priority is high for systems using luksmeta in administrative privilege contexts.

Technical summary

The luksmeta flaw allows a local attacker with administrative privileges to cause data corruption when saving metadata to a Linux Unified Key Setup (LUKS) device. This is due to incorrect boundary calculations and flawed overlap detection in the luks1 metadata allocator. The issue can corrupt stored encrypted payload data or existing metadata, potentially rendering the affected data inaccessible. Remediation priority is high for systems using luksmeta in administrative privilege contexts. Assess exposure and prioritize remediation for systems using luksmeta, especially in administrative privilege contexts. Verify specific versions affected and remediation steps from official sources.

Defensive priority

Assess exposure and prioritize remediation for systems using luksmeta, especially in administrative privilege contexts.

Recommended defensive actions

• Assess systems using luksmeta for exposure
• Prioritize remediation for administrative privilege contexts
• Verify specific versions affected and remediation steps from official sources
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the flaw in luksmeta's metadata allocator, which allows for data corruption. However, specific versions affected and remediation steps require verification from official sources.
