  "details" : [ "In the Linux kernel, the following vulnerability has been resolved:\nRDMA/hns: Fix unlocked call to hns_roce_qp_remove()\nSashiko points out that hns_roce_qp_remove() requires the caller to hold\nlocks.  The error flow in hns_roce_create_qp_common() doesn't hold those\nlocks for the error unwind so it risks corrupting memory.\nGrab the same locks the other two callers use.", "A flaw was found in the Linux kernel's RDMA/hns component. An issue exists where the `hns_roce_qp_remove()` function is called without proper locking during an error handling process. This can lead to memory corruption, potentially causing system instability or a denial of service (DoS) condition. A local attacker could exploit this vulnerability." ],
