Local information disclosure via out-of-bounds read
Published Nov 14, 2023 · Updated Oct 8, 2025
Out-of-bounds read in LSASS in Microsoft Windows allows local users to disclose sensitive memory through a crafted local operation. Microsoft identifies LSASS as the affected component but has not published the specific function, input, or erroneous read sequence. Exploitation requires low-privileged local access; the documented consequence is confidentiality loss without integrity or availability impact.
