CVE-2026-99205

A flaw was found in the Linux kernel's task scheduler. A race condition occurs when updating the scheduling class of a queued task, which can prevent the system from recognizing higher-priority tasks that are ready to run. A local user could exploit this timing issue to cause central processing unit (CPU) cores to remain idle instead of executing waiting processes, resulting in thread starvation and a Denial of Service (DoS).
