Changes in v2:

• The potential vulnerability was discovered as follows: based on our

customized static analysis tool, extract vulnerability features[1], and then match similar vulnerability features in this function.

You need to follow the rules outlined in Documentation/process/researcher-guidelines.rst when doing stuff like this. Otherwise all of your patches will have to be rejected.

Please fix up the changelog text of all of the patches you have submitted recently to follow those rules.
