Adjacent code execution via heap buffer overflow
Published Sep 12, 2023 · Updated Oct 30, 2025
Heap-based buffer overflow in Microsoft Windows Miracast Wireless Display allows unauthenticated nearby attackers to execute code. Microsoft has not disclosed the affected parser, malformed field, or memory operation that overruns the heap. Exploitation requires the target to share a wireless network, have Projecting to this PC enabled, and use the non-default Available Everywhere setting.
