            Bug ID: 220485
           Summary: security.bsd.stack_guard_page can be set to a negative
                    integer value
           Product: Base System
           Version: 11.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: shawn.webb@hardenedbsd.org

On FreeBSD 12-CURRENT and 11-STABLE, the security.bsd.stack_guard_page sysc=
tl
node can be set to a negative integer value. Doing so will cause applicatio=
ns
to crash with SIGABRT.
