Elevation of Privilege in Microsoft Windows Graphics Component
CVE-2026-20822 is a use-after-free vulnerability in the Microsoft Windows Graphics Component. The provided content states that the flaw allows an authorized local attacker to elevate privileges, and multiple supporting summaries characterize it as a Critical elevation-of-privilege issue with CVSS 7.8. The vulnerability is described as affecting Windows graphics functionality and, upon successful exploitation, can allow a low-privileged authenticated attacker to obtain SYSTEM-level access. The content further notes that in some GPU paravirtualization scenarios the issue may cross security boundaries, indicating potential impact beyond a simple local user-to-SYSTEM transition in certain virtualized graphics environments. No specific vulnerable function or code path is provided in the source material.
