Unauthenticated service interruption via out-of-bounds read
Published Apr 11, 2023 · Updated Jan 23, 2025
Out-of-bounds read in Microsoft Windows Secure Channel allows remote attackers to interrupt service via network traffic. Microsoft identifies CWE-125 but has not disclosed the Schannel parsing locus or network input that drives the read beyond a buffer boundary. No authentication or user interaction is required; exploitation affects availability without reported data disclosure or modification.
