CVE-2026-97987
Description
In the Linux kernel, the following vulnerability has been resolved:
virtio_input: reset device if input_register_device() fails
Probe marks the device DRIVER_OK with virtio_device_ready() before calling input_register_device(). If registration fails, the error path cleared vi->ready and called del_vqs() while the device was still live, so the device could keep DMA to queues that were already torn down.
Match remove/freeze: call virtio_reset_device() on that path before tearing down the virtqueues.
