Local privilege escalation via undisclosed out-of-bounds read
Published Nov 12, 2024 · Updated Jul 8, 2025
An out-of-bounds read in Microsoft Windows Client-Side Caching allows local users to elevate privileges on affected Windows systems. Microsoft has not published the precise code locus or the invalid boundary operation performed on untrusted input. Exploitation requires existing low privileges and local access; success can compromise system confidentiality, integrity, and availability.
