In the Linux kernel, the following vulnerability has been resolved: eth: bnxt: avoid deadlock when canceling IRQ affinity notifier Unregistering IRQ affinity notifiers waits for the callback synchronously. bnxt takes the netdev instance lock in the notifier (to restart the queue) and cancels the work under the same lock. This may obviously deadlock. Move the restart to the async service task. T…
