DescriptionCVE.org

Use after free in Windows Internal System User Profile allows an authorized attacker to elevate privileges locally.

AnalysisAI

Local privilege escalation in the Windows Internal System User Profile component allows an already-authenticated attacker to gain elevated (SYSTEM-level) privileges by triggering a use-after-free memory corruption condition (CWE-416). The flaw affects Windows 10 (21H2/22H2), Windows 11 (24H2/25H2/26H1), and Windows Server 2025 including Server Core. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but the CVSS 7.8 rating and full high impact on confidentiality, integrity, and availability make it a meaningful patch-cycle priority.
