2) Incorrect authorization

EUVDB-ID: #VU74549

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-20572

CWE-ID: CWE-863 - Incorrect Authorization

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a missing permission check within the verity_target() function in dm-verity-target.c. A local user can modify read-only files and escalate privileges on the system.

Mitigation

Install updates from vendor's repository.
