Code execution via undisclosed graphics processing flaw
Published Aug 12, 2021 · Updated Aug 10, 2026
Remote code execution in Microsoft Windows Graphics Component allows local users to execute code after opening crafted content. Microsoft has not disclosed the affected graphics-processing locus or the incorrect operation performed on attacker-controlled data. Successful exploitation requires user interaction and runs code in the targeted user's security context, enabling the data access and system changes permitted to that account.
