Unfortunately, state-of-the-art defenses against use-after-free vulnerabilities require compiler support, pervasive source code modifications, or incur high performance ... WebDangling pointers likely abound in programs using manual memory management, because consistent manual memory management across large programs is notoriously error prone. Some dan-gling pointer bugs cause crashes and can be discovered during early testing, but others may go unnoticed be-cause the dangling pointer is either not created or not
