Aug 4 RESCORED — CVE-2023-53116 (Linux). CVSS 9.8 → 7.8 (NVD).
Description
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.
