DescriptionCVE.org

Heap-based buffer overflow in Microsoft Windows Search Component allows an authorized attacker to elevate privileges locally.

AnalysisAI

Local privilege escalation in the Microsoft Windows Search Component affects Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025, where a heap-based buffer overflow lets an already-authenticated local attacker corrupt memory and elevate to higher privileges (up to SYSTEM). The CVSS 3.1 score of 7.8 reflects local-only attack with low privileges required and no user interaction, yielding full confidentiality, integrity, and availability impact. …
