Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvme-tcp: fix possible use-after-free in transport error_recovery work<br /> <br /> While nvme_tcp_submit_async_event_work is checking the ctrl and queue<br /> state before preparing the AER command and scheduling io_work, in order<br /> to fully prevent a race where this check is not reliable the error<br /> recovery work must flush async_event_work before continuing to destroy<br /> the admin queue after setting the ctrl state to RESETTING such that<br /> there is no race .submit_async_event and the error recovery handler<br /> itself changing the ctrl state.
