Technical Description

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

sound/virtio: Fix cancel_sync warnings on uninitialized work_structs

Betty reported hitting the following warning:

[ 8.709131][ T221] WARNING: CPU: 2 PID: 221 at kernel/workqueue.c:4182

...

It seems we're hitting the error path in virtsnd_probe(), which

triggers a virtsnd_remove() which iterates over the substreams

calling cancel_work_sync() on the elapsed_period work_struct.
