Description OSIDB Bzimport 2026-10-06 09:27:54 UTC
In the Linux kernel, the following vulnerability has been resolved:

ALSA: virtio: reset device before deleting virtqueues

virtsnd_remove() and virtsnd_freeze() delete the virtqueues before
resetting the device. del_vqs() frees the vring backing, but does not
provide a generic device quiesce operation. In particular, modern
virtio-pci keeps enabled queues active until the device is reset.

Reset the device before deleting the virtqueues so it can no longer
access the vring memory when that memory is released. This also covers
probe failures after DRIVER_OK, which unwind through virtsnd_remove().
