CVE-2026-46112

Summary

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.
