2) Security restrictions bypass

EUVDB-ID: #VU61258

Risk: Low

CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-4197

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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

The vulnerability exists due to missing permissions checks within the cgroups (control groups) functionality of Linux Kernel when writing into a file descriptor. A local low privileged process can trick a higher privileged parent process into writing arbitrary data into files, which can result in denial of service or privileges escalation.

Mitigation

Update the affected package linux to the latest version.
