Authenticated information disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 10, 2026
Out-of-bounds read in Microsoft Windows SMB Client allows remote authenticated users to disclose information through an SMB exchange. Microsoft has not published the specific SMB Client parsing locus or the unchecked length or offset that causes the read beyond its buffer. Exploitation requires low privileges and user interaction, and the reported consequence is disclosure without data modification or service interruption.
