In the Linux kernel, the following vulnerability has been resolved:
nvme: move stopping keep-alive into nvme_uninit_ctrl()
Commit 4733b65d82bd ("nvme: start keep-alive after admin queue setup")
moves starting keep-alive from nvme_start_ctrl() into
nvme_init_ctrl_finish(), but don't move stopping keep-alive into
nvme_uninit_ctrl(), so keep-alive work can be started and keep pending
after failing to start controller, finally use-after-free is triggered if
nvme host driver is unloaded.
This patch fixes kernel panic when running nvme/004 in case that connection
failure is triggered, by moving stopping keep-alive into nvme_uninit_ctrl().
This way is reasonable because keep-alive is now started in
nvme_init_ctrl_finish().
