How to fix?

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

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-64k-debug-modules-partner package and not the kernel-64k-debug-modules-partner 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:

hsr: Prevent use after free in prp_create_tagged_frame()

The prp_fill_rct() function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to fix bug by using the returned value.
