CVE-2021-4122 (GCVE-0-2021-4122)

Vulnerability from cvelistv5 – Published: 2022-08-24 15:08 – Updated: 2024-08-03 17:16
VLAI
Summary
It was found that a specially crafted LUKS header could trick cryptsetup into disabling encryption during the recovery of the device. An attacker with physical access to the medium, such as a flash disk, could use this flaw to force a user into permanently disabling the encryption layer of that medium.
