Applicable for: Wind River Linux LTS 17
Component/s: Kernel

Description

"sched/fair: Use RCU accessors consistently for ->numa_group
 The old code used RCU annotations and accessors inconsistently for ->numa_group, which can lead to use-after-frees and NULL dereferences. Let all accesses to ->numa_group use proper RCU helpers to prevent such issues."
