CVE-2025-59215

Local privilege escalation via graphics use-after-free

Published Sep 18, 2025 · Updated Sep 18, 2025

Use-after-free in Microsoft Windows 11 24H2 and Server 2025 before 10.0.26100.6584 allows local users to elevate privileges. The Graphics Component accesses freed memory, but Microsoft has not disclosed the affected object, function, or input sequence that triggers reuse. Low-privileged local access and a high-complexity state condition are required; successful exploitation grants higher privileges.
