CVE-2022-48789

Summary

In the Linux kernel, the following vulnerability has been resolved:

nvme-tcp: fix possible use-after-free in transport error_recovery work

While nvme_tcp_submit_async_event_work is checking the ctrl and queue state before preparing the AER command and scheduling io_work, in order to fully prevent a race where this check is not reliable the error recovery work must flush async_event_work before continuing to destroy the admin queue after setting the ctrl state to RESETTING such that there is no race .submit_async_event and the error recovery handler itself changing the ctrl state.
