CVE-2026-89520

CVE-2026-89520 is a race condition in the Linux kernel's core scheduling component. When pick_next_task() releases the runqueue lock during task selection, sibling locks become momentarily free, allowing __sched_core_flip(false) to rebind rq_lockp() mid-selection. The selection then resumes on sp...
