Detailsinfo

A vulnerability was found in Red Hat Enterprise Linux and OpenShift Container Platform (affected version unknown). It has been rated as problematic. Affected by this issue is an unknown functionality of the component LUKS1 Disk Encryption. The manipulation with an unknown input leads to a improper validation of specified quantity in input vulnerability. Using CWE to declare the problem leads to CWE-1284. The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties. Impacted is integrity. CVE summarizes:

A data corruption vulnerability has been identified in the luksmeta utility when used with the LUKS1 disk encryption format. An attacker with the necessary permissions can exploit this flaw by writing a large amount of metadata to an encrypted device. The utility fails to correctly validate the available space, causing the metadata to overwrite and corrupt the user's encrypted data. This action leads to a permanent loss of the stored information. Devices using the LUKS formats other than LUKS1 are not affected by this issue.

The advisory is available at access.redhat.com. This vulnerability is handled as CVE-2025-11568 since 10/09/2025. The exploitation is known to be easy. Local access is required to approach this attack. Additional levels of successful authentication are required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 05/19/2026).

The vulnerability scanner Nessus provides a plugin with the ID 271687 (Linux Distros Unpatched Vulnerability : CVE-2025-11568), which helps to determine the existence of the flaw in a target environment.
