How to fix?

Upgrade SLES:16.0.0 kernel-default-base to version 6.12.0-160000.36.1.160000.2.17 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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

RDMA/hns: Fix unlocked call to hns_roce_qp_remove()

Sashiko points out that hns_roce_qp_remove() requires the caller to hold locks. The error flow in hns_roce_create_qp_common() doesn't hold those locks for the error unwind so it risks corrupting memory.

Grab the same locks the other two callers use.
