CVE-2026-23360: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.1% chance of exploitation in the next 30 days.

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").
