Description
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to improper resource management in the NVMe subsystem when handling controller resets. A local user can trigger a controller reset to cause a denial of service due to an admin queue leak.
The issue arises when nvme_alloc_admin_tag_set() is called during a controller reset while a previous admin queue still exists, leading to resource exhaustion over time.
Remediation
Install security update from vendor's repository.
