https://notcve.org/view.php?id=CVE-2021-4122
02 Feb 2022 — 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. Se ha detectado que un encabezado LUKS especialmente diseñada podía engañar a cryptsetup para que deshabilitara el cifrado durante la recuperación del dispositivo. Un atacante con acceso físico al medio, como... • https://access.redhat.com/security/cve/CVE-2021-4122 • CWE-345: Insufficient Verification of Data Authenticity CWE-349: Acceptance of Extraneous Untrusted Data With Trusted Data •
