Description OSIDB Bzimport 2026-05-28 11:04:15 UTC 
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.
