CVE-2022-49497 Details
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.
A vulnerability has been identified in the Linux kernel's networking component, specifically within the skb_checksum_help() function. This issue arises from the presence of two BUG() calls, which can lead to a crash. The syzbot tool has reported the ability to trigger these BUG() calls, indicating a flaw that needs to be addressed. The current BUG() calls could be replaced with WARN_ON_ONCE() to allow skb_checksum_help() to return an error code instead. However, it's important to note that syzbot will still cause a crash until the underlying issue is resolved.
