The Centos security team deemed this advisory irrelevant for Centos:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k package and not the kernel-rt-64k package as distributed by Centos.
In the Linux kernel, the following vulnerability has been resolved:
RDMA/efa: Fix wrong resources deallocation order
When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If the device fails, the object isn't fully destroyed so the user/IB core can try to destroy the object again which will lead to underflow when trying to decrease an already zeroed refcount.
Deallocate resources in reverse order of allocating them to safely free them.
