CVE-2021-4122 (CCN-217238)

Assigned:2021-12-15
Published:2022-01-13
Updated:2022-08-29
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.
