Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 17 Dec 2025. US federal agencies had to remediate by 7 Jan 2026, a deadline that has passed.

Required action. Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Description

"UNSUPPORTED WHEN ASSIGNED" Certain versions of the ASUS Live Update client were distributed with unauthorized modifications introduced through a supply chain compromise. The modified builds could cause devices meeting specific targeting conditions to perform unintended actions. Only devices that met these conditions and installed the compromised versions were affected. The Live Update client has already reached End-of-Support (EOS) in October 2021, and no currently supported devices or products are affected by this issue.
