CVE-2023-53116

  2. Vulnerabilities (CVE)
  3. CVE-2023-53116
In the Linux kernel, the following vulnerability has been resolved: nvmet: avoid potential UAF in nvmet_req_complete() An nvme target ->queue_response() operation implementation may free the request passed as argument. Such implementation potentially could result in a use after free of the request pointer when percpu_ref_put() is called in nvmet_req_complete(). Avoid such problem by using a local variable to save the sq pointer before calling __nvmet_req_complete(), thus avoiding dereferencing the req pointer after that function call.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nvmet: evitar posible UAF en nvmet_req_complete(). La implementación de la operación nvme target ->queue_response() puede liberar la solicitud pasada como argumento. Esta implementación podría provocar un use after free del puntero de solicitud al llamar a percpu_ref_put() en nvmet_req_complete(). Para evitar este problema, utilice una variable local para guardar el puntero sq antes de llamar a __nvmet_req_complete(), evitando así la desreferenciación del puntero req después de esa llamada.
