Description
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.
Affected configurations
• linux linux kernel (< 5.10.121)
• linux linux kernel (>= 5.11 < 5.15.46)
• linux linux kernel (>= 5.16 < 5.17.14)
• linux linux kernel (>= 5.18 < 5.18.3)
