Information disclosure via out-of-bounds MapUrlToZone read
Published Oct 14, 2025 · Updated Oct 14, 2025
Out-of-bounds read in Microsoft Windows MapUrlToZone allows remote attackers to disclose information through crafted network content. Microsoft has not disclosed the specific parser, buffer, or bounds-checking operation that reads beyond its valid memory region. Exploitation requires user interaction; exposed memory can contain sensitive data, while service interruption or code execution is not reported.
