Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 11/17/2023
=====================================================
This issue occurs because the skb buffer is too small, and it's actual
allocation is aligned. This hides an actual issue, which is that nr_route_frame
does not validate the buffer size before using it.
Fix this issue by checking skb->len before accessing any fields in skb->data.
Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
