Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： virtio_input：当 input_register_device() 失败时，重置设备 探测过程中，在调用 input_register_device() 之前，会通过 virtio_device_ready() 将设备标记为 DRIVER_OK。如果注册失败，错误处理路径会清除 vi->ready 标志并调用 del_vqs()，而此时设备仍处于活跃状态，因此可能导致设备继续向已被销毁的队列进行 DMA 操作。 为了解决这个问题，在该错误路径上，在销毁 virtq

Vulnerability Title
virtio_input: reset device if input_register_device() fails
Source: CVE Program / CVE List V5
Vulnerability 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.
