Description
The issue is related to a use-after-free vulnerability in the
nvme rdma error recovery work() function. This vulnerability can be exploited due to a race condition, potentially affecting the confidentiality, integrity, and availability of protected information. The vulnerability occurs when nvme rdma submit async event work checks the controller and queue state before preparing the AER command and scheduling io work. To prevent this race, the error recovery work must flush async event work before destroying the admin queue after setting the controller state to RESETTING.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
