CVE-2023-53116

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvmet: avoid potential UAF in nvmet_req_complete()<br /> <br /> An nvme target -&gt;queue_response() operation implementation may free the<br /> request passed as argument. Such implementation potentially could result<br /> in a use after free of the request pointer when percpu_ref_put() is<br /> called in nvmet_req_complete().<br /> <br /> Avoid such problem by using a local variable to save the sq pointer<br /> before calling __nvmet_req_complete(), thus avoiding dereferencing the<br /> req pointer after that function call.
