- Summary
- net: remove two BUG() from skb_checksum_help()
- Details
-
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.
