CVE-2022-49497

Описание

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

net: remove two BUG() from skb_checksum_help()

I have a syzbot report that managed to get a crash in skb_checksum_help()

If syzbot can trigger these BUG(), it makes sense to replace them with more friendly WARN_ON_ONCE() since skb_checksum_help() can instead return an error code.

Note that syzbot will still crash there, until real bug is fixed.
