Description OSIDB Bzimport 2026-03-25 11:04:11 UTC 
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").
