What is CVE-2025-11568?
CVE-2025-11568 is a medium-severity vulnerability in Latchset Red Hat Enterprise Linux 10, published on 15 Oct 2025. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-1284
