Local privilege escalation via out-of-bounds read
Published Oct 13, 2026 · Updated Oct 13, 2026
An out-of-bounds read in Microsoft Windows DWM Core Library allows local users to elevate privileges via unspecified vectors. The supplied record names DWM Core Library, but the affected routine, triggering input, and route from the invalid read to elevated privileges were not retrievable from the public sources checked. Exploitation requires an authorized local attacker; the resulting privilege level and additional preconditions remain unspecified.
