Overview

CVE-2023-53116 is a critical-severity vulnerability. It was published on May 2, 2025 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
