No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

A vulnerability has been identified in the Acer System Monitoring component included with NitroSense and PredatorSense. Insufficient access controls within a privileged Named Pipe service may allow an authenticated local user to perform unauthorized registry operations. In certain situations, this could lead to privilege escalation or compromise of the affected system.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact total (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
