Unauthenticated service interruption via RPC buffer over-read
Published May 9, 2023 · Updated Jul 10, 2025
Buffer over-read in Microsoft Windows RPC Runtime allows remote attackers to interrupt service through crafted network traffic. Microsoft identifies an out-of-bounds read in the RPC Runtime but does not disclose the affected function, buffer, or parsing operation. No authentication or user interaction is required; successful exploitation affects availability without reported confidentiality or integrity impact.
