How to fix?

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

NVD Description

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

In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.
