Hi,
I was looking at this syzbot issue : https://syzkaller.appspot.com/bug?extid=ef50f8eb00b54feb7ba2
While debugging I found that when we are traversing through the attribute list, there is case when the next attribute is null (most likely we are traversing out of the list) and thus there is this error. I was wondering if we could add a size field to this attribute list. This would fix this issue. Currently we are just parsing to the next attribute using the length field.
