How to fix?

There is no fixed version for RHEL:9 kernel-64k-debug-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-core package and not the kernel-64k-debug-core package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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

sched: Fix yet more sched_fork() races

Where commit 4ef0c5c6b5ba ("kernel/sched: Fix sched_fork() access an invalid sched_task_group") fixed a fork race vs cgroup, it opened up a race vs syscalls by not placing the task on the runqueue before it gets exposed through the pidhash.

Commit 13765de8148f ("sched/fair: Fix fault in reweight_entity") is trying to fix a single instance of this, instead fix the whole class of issues, effectively reverting this commit.
