Local service-memory disclosure via out-of-bounds read
Published Jan 13, 2026 · Updated Jan 13, 2026
Out-of-bounds read in Microsoft Windows camsvc allows local users with low privileges to disclose service memory on affected systems. Microsoft has not published the vulnerable function, input path, or bounds-checking failure that causes camsvc to read beyond the intended buffer. Low-privilege local access is required, no user interaction is needed, and successful exploitation reveals camsvc process memory without altering data or interrupting service.
