CVE-2026-9489

SYSTEM code execution via misconfigured named pipe

Published May 25, 2026 · Updated May 25, 2026

Local privilege escalation in Acer NitroSense 3.01.3001 through 3.01.3052 allows local users to execute arbitrary code as SYSTEM. A Windows named pipe exposes a custom internal-function protocol with permissions that admit authenticated low-privilege users. Such users can invoke privileged operations to execute code or delete arbitrary files with NT AUTHORITY\SYSTEM rights.
