Frequently Asked Questions
What does an attacker need to exploit this issue?
The attack vector is network-based and requires no privileges or prior authentication. User interaction is required, so exploitation depends on a user interacting with attacker-controlled content or a network-delivered attack scenario.
Which systems should be prioritized for triage?
Prioritize Microsoft Windows 10, Windows 11, Windows Server 2016, Windows Server 2019, Windows Server 2022, and Windows Server 2025 systems. The provided information does not identify specific affected builds or update levels within those product families.
What impact is indicated if exploitation succeeds?
Successful exploitation can allow code execution and is rated as having high impact to confidentiality, integrity, and availability. The underlying weakness is a stack-based buffer overflow in the Microsoft Graphics Component.
