Summary
tap: add missing verification for short frame
Details

In the Linux kernel, the following vulnerability has been resolved:

tap: add missing verification for short frame

The cited commit missed to check against the validity of the frame length in the tapgetuserxdp() path, which could cause a corrupted skb to be sent downstack. Even before the skb is transmitted, the tapgetuserxdp()-->skbsetnetworkheader() may assume the size is more than ETHHLEN. Once transmitted, this could either cause out-of-bound access beyond the actual length, or confuse the underlayer with incorrect or inconsistent header length in the skb metadata.

In the alternative path, tapgetuser() already prohibits short frame which has the length less than Ethernet header size from being transmitted.

This is to drop any frame shorter than the Ethernet header size just like how tapgetuser() does.
