Such implementation potentially could result\nin a use after free of the request pointer when percpu_ref_put() is\ncalled in nvmet_req_complete().\n\nAvoid such problem by using a local variable to save the sq pointer\nbefore calling __nvmet_req_complete(), thus avoiding dereferencing the\nreq pointer after that function call."

"value": "AV:N - The vulnerable code is in the shared NVMe target core and is reachable via network-facing transports such as nvmet-tcp and nvmet-rdma, which accept remote NVMe-oF connections and complete requests through nvmet_req_complete().\nAC:L - An attacker who can send NVMe commands reliably drives request completion; on FC the abort path frees the request synchronously inside queue_response, and on TCP/RDMA concurrent requests create a reuse race the attacker controls.\nPR:N - The discovery subsystem allows any host without credentials, DH-CHAP auth is optional, and allow_any_host deployments accept unauthenticated connects, so a remote peer can reach nvmet_req_complete with no privileges.\nUI:N - Exploitation requires only attacker-sent NVMe-oF traffic to a configured target; no victim user action is needed.\nS:U - This is memory corruption within the host kernel's NVMe target authority and does not cross a VM, IOMMU, or other security boundary.\nC:H - Use-after-free of the request object allows reuse/spray of the freed structure, which can be leveraged for arbitrary kernel memory disclosure.\nI:H - The same UAF/reuse of the nvmet request enables attacker-controlled heap contents and corruption suitable for arbitrary write or control-flow hijacking.\nA:H - Dereferencing the freed request (e.g., req->sq for percpu_ref_put) can crash the kernel via oops/panic even when not fully exploited for code execution."
