- Summary
- CVE-2025-39718 affecting package kernel for versions less than 6.6.104.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
vsock/virtio: Validate length in packet header before skb_put()
When receiving a vsock packet in the guest, only the virtqueue buffer size is validated prior to virtiovsockskbrxput(). Unfortunately, virtiovsockskbrxput() uses the length from the packet header as the length argument to skb_put(), potentially resulting in SKB overflow if the host has gone wonky.
Validate the length as advertised by the packet header before calling virtiovsockskbrxput().
