1) Security features bypass

EUVDB-ID: #VU66592

Risk: Low

CVSSv4.0: 4 [CVSS:4.0/AV:P/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-21505

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows an attacker to bypass implemented security restrictions.

The vulnerability exists due to incorrect implementation of the IMA lockdown feature. If IMA appraisal is used with the "ima_appraise=log" boot param, lockdown can be defeated with kexec on any machine with Secure Boot. An attacker with physical access to device can bypass Secure Boot mechanism.
