Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: remove two BUG() from skb_checksum_help()<br /> <br /> I have a syzbot report that managed to get a crash in skb_checksum_help()<br /> <br /> If syzbot can trigger these BUG(), it makes sense to replace<br /> them with more friendly WARN_ON_ONCE() since skb_checksum_help()<br /> can instead return an error code.<br /> <br /> Note that syzbot will still crash there, until real bug is fixed.
