**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A vulnerability has been resolved in the Linux kernel related to the virtio-pci module. The issue involves the `vp dev->is avq` function being empty in certain installations, specifically when `virtio pci legacy` does not assign a value to it. This emptiness can cause the guest system to crash when the `virsh Attach device` command is used. The vulnerability is related to the `vp del vqs` function in the `virtio pci common.c` file, where `vp dev->is avq` is used to determine whether it is an admin virtqueue. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
