Overview

CVE-2026-23360 is a medium-severity vulnerability affecting linux linux_kernel. It was published on March 25, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

nvme: fix admin queue leak on controller reset

When nvme_alloc_admin_tag_set() is called during a controller reset,

a previous admin queue may still exist. Release it properly before

allocating a new one to avoid orphaning the old queue.

This fixes a regression introduced by commit 03b3bcd319b3 ("nvme: fix

admin request_queue lifetime").

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. 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.
