Security Bulletin

This security bulletin contains information about 8 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU78673

Risk: Low

CVSSv4.0: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Clear]

CVE-ID: CVE-2023-2640

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

Exploit availability: Yes

Description

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

The vulnerability exists due to missing permission checks for trusted.overlayfs.* xattrs". A local user can set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks.

Mitigation

Update the affected package linux to the latest version.
