Bug ID: 23965
Summary: False positive in checker: Use of memory after it is
freed
Product: clang
Version: unspecified
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: Static Analyzer
Assignee: [email protected]

Created attachment 14522
--> https://llvm.org/bugs/attachment.cgi?id=14522&action=edit
Original source file (airserv-ng.c)
When analyzing airserv-ng.c, clang reports a use after free.
https://github.com/aircrack-ng/aircrack-ng/blob/master/src/airserv-ng.c#L140
However, the memory is NULLed immediately after the call to free. Therefore, if
(c == NULL) is true and it breaks out of the loop.
