CVE-2026-98972

The Linux kernel contains a vulnerability in the cgroup/cpuset subsystem where the is_in_v2_mode() helper function could potentially access a stale cpuset_cgrp_subsys.root pointer during a cgroup filesystem rebind. This creates a potential Use-After-Free (UaF) situation. To remediate this, a new ...
