#10221 closed bug (fixed)

Fixed arbitrary memory reading

Description

Found this in Coverity, CID:1108404

But, I'm 99% sure it is just false positive. I created tihs ticket because it may be serious bug.

Method BuildReportList reads what contains table of pointers of second parameter. But, this was uninitialized.

I saw this is 99% false positive because if it's kernel mode this willn't crash machine. But I saw preprocessor constant with word USERLAND and I'm not sure if it's kernel mode. If it's, setting this array to nulls is probably only wasting cpu cycles.
