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