Local information disclosure via camsvc out-of-bounds read
Published Jan 13, 2026 · Updated Jan 13, 2026
Out-of-bounds read in Microsoft Windows camsvc allows local users to disclose information from affected system memory. Microsoft identifies Capability Access Management Service as the locus but has not published the input, code path, or bounds-checking failure that causes the read. Local access is required; exploitation exposes memory information without reported modification or service interruption.
