NVD Description
Note: Versions mentioned in the description apply only to the upstream perf package and not the perf package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
perf: Fix list corruption in perf_cgroup_switch()
There's list corruption on cgrp_cpuctx_list. This happens on the following path:
perf_cgroup_switch: list_for_each_entry(cgrp_cpuctx_list) cpu_ctx_sched_in ctx_sched_in ctx_pinned_sched_in merge_sched_in perf_cgroup_event_disable: remove the event from the list
Use list_for_each_entry_safe() to allow removing an entry during iteration.
