CVE-2026-99065

A flaw was found in the Linux kernel's cpuset subsystem. A race condition during CPU hotplug offline operations can leave the root control group with no active processors before CPU masks are updated, resulting in a null pointer dereference. A privileged local user or process initiating CPU...

CVE-2026-99065

The Linux kernel is affected by a CPU hotplug race condition within the cgroup/cpuset subsystem, specifically in the guarantee_active_cpus() function. The issue arises during CPU offline operations because the cpu_active_mask is updated in sched_cpu_deactivate() before cpuset_handle_hotplug() can...

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 ...
