CVE-2024-49573

Estado: ModificadaMedia (5.5)—

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

sched/fair: Fix NEXT_BUDDY

Adam reports that enabling NEXT_BUDDY insta triggers a WARN in pick_next_entity().

Moving clear_buddies() up before the delayed dequeue bits ensures no ->next buddy becomes delayed. Further ensure no new ->next buddy ever starts as delayed.
