Local privilege escalation via DirectComposition memory mishandling
Published Mar 12, 2020 · Updated Aug 4, 2024
Privilege escalation in the Windows Graphics Component in Windows 10 Version 1607 and Windows Server 2016 allows local users to elevate privileges. The DirectComposition component mishandles in-memory objects, but Microsoft has not disclosed the specific operation or memory-safety error. A local low-privileged user must run a specially crafted application; successful exploitation runs processes in an elevated context.
