Local privilege escalation via Win32k object handling
Published Apr 15, 2020 · Updated Aug 4, 2024
Windows Win32k elevation of privilege in Microsoft Windows 10 1903 and earlier allows local users to gain SYSTEM privileges via crafted objects in kernel memory. The Windows kernel-mode Win32k driver improperly handles objects in memory, enabling a low-privileged process to cross into higher privileges. Exploitation requires local logon and code execution; the resulting impact includes elevated confidentiality, integrity, and availability access.
