Overview

CVE-2025-68733 is a known-severity vulnerability. It was published on December 24, 2025.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

smack: fix bug: unprivileged task can create labels

If an unprivileged task is allowed to relabel itself

(/smack/relabel-self is not empty),

it can freely create new labels by writing their

names into own /proc/PID/attr/smack/current

This occurs because do_setattr() imports

the provided label in advance,

before checking "relabel-self" list.

This change ensures that the "relabel-self" list

is checked before importing the label.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
