Overview
About vulnerability
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”). A flaw was found in the Linux kernel’s Non-Volatile Memory Express (NVMe) subsystem. When an NVMe controller is reset, a previously allocated administration queue may not be properly released before a new one is created. This can lead to the old queue becoming orphaned, potentially causing resource exhaustion or system instability over time.Details
