In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix UAF for cq async event
The refcount of CQ is not protected by locks. When CQ asynchronous
events and CQ destruction are concurrent, CQ may have been released,
which will cause UAF.
Use the xa_lock() to protect the CQ refcount.
