Frequently Asked Questions

1

Which systems are exposed to this issue?

Systems using the Linux kernel's virtio sound (virtsnd) driver are relevant. The issue affects device removal, suspend/freezing, and probe-failure cleanup paths after the virtio device has reached DRIVER_OK.

2

What condition creates the unsafe state?

A virtio device can keep its queues active until it is reset. If the driver deletes virtqueues first, the vring backing memory may be released while the device can still access it.

3

How can I tell whether a kernel includes the fix?

Check whether the kernel contains one of the referenced stable commits: 8edc3669e3e22f0123a1114c3a03df9abc4cd465, 830012feadc228a938514a6487862dcf56af7e66, or 500a8401415ab085555785c3c339747e378abd36. The corrected behavior resets the device before deleting virtqueues.
