Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A flaw exists in the Linux kernel’s vsock/virtio subsystem. The vulnerability occurs when receiving a vsock packet in the guest, where the length from the packet header is used as the argument to
skb put() without proper validation. This can lead to a SKB (socket buffer) overflow if the host provides an incorrect length. The issue resides in the lack of validation of the length advertised by the packet header before calling virtio vsock skb rx put().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
