Windows access violations across apps point to execution of zeroed memory

devblogs.microsoft.com by Raymond Chen 4 min read Editor score 6/10

Crash dumps from unrelated programs show execution of an `add` instruction encoded by zero bytes, indicating execution of invalid code. The cross-process pattern makes this a useful debugging investigation for engineers tracing system-wide failures.

What

Unrelated Windows programs were crashing with access violations, and their dumps showed execution of zeroed bytes rather than valid code.

How

Disassembly suggested a failed function detour; an executable private-memory block contained a path to injcore.dll.

Why it matters

Because crashes spanned unrelated apps, engineers should investigate shared injected code as well as each application's own code.
