There is no fixed version for RHEL:9 kernel-zfcpdump-modules-internal.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-internal package and not the kernel-zfcpdump-modules-internal 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:
workqueue: Don't call cpumask_test_cpu() with -1 CPU in wq_update_node_max_active()
For wq_update_node_max_active(), @off_cpu of -1 indicates that no CPU is going down. The function was incorrectly calling cpumask_test_cpu() with -1 CPU leading to oopses like the following on some archs:
Unable to handle kernel paging request at virtual address ffff0002100296e0 .. pc : wq_update_node_max_active+0x50/0x1fc lr : wq_update_node_max_active+0x1f0/0x1fc ...

Fix it.
