Riot Games Detects Critical Vulnerability in Motherboards from Multiple Manufacturers

The video game developer Riot Games has discovered a significant security breach affecting hardware components of millions of users. This flaw compromises motherboards from leading brands like Asus, Gigabyte, MSI, and ASRock, allowing some players to bypass the controls of their anti-cheat system, Vanguard. The immediate response has been to block access to Valorant on at-risk systems. 🔒

Manufacturers Respond with Urgent BIOS Patches

Following Riot's alert, the main involved manufacturers have quickly distributed BIOS updates that resolve this issue. The company confirmed that Asus, Gigabyte, MSI, and ASRock have already released the corresponding patches. Riot emphasizes that it is now the user's responsibility to install these fixes on their system. Those who do not act face a direct consequence: blocking of their account in Valorant until they resolve the vulnerability.

Key measures implemented by Riot Games:
  • Automatic detection and blocking of accounts using vulnerable hardware.
  • Official communication urging users to update the motherboard firmware on a priority basis.
  • Confirmation that the manufacturers' patches resolve the security flaw.
By forcing BIOS updates, the company closes that door and maintains a fairer gaming environment for everyone.

Protecting Competitive Integrity is the Priority

This action is part of Riot Games' ongoing effort to protect fairness in their titles. The Vanguard system operates at a very deep level of the system to detect cheats. The vulnerability in the motherboard firmware represented a blind spot that dishonest players could exploit. The decision, although it has generated debate in the community, is considered necessary to preserve the legitimacy of the competitive experience in games like League of Legends and Valorant.

Consequences of not applying the patch:
  • Inability to access Valorant with the affected account.
  • Permanent risk that exploits take advantage of the hardware flaw.
  • Being excluded from the safe gaming environment that Vanguard aims to guarantee.

A Call to Action Beyond System Stability

This episode changes the usual paradigm regarding BIOS updates. For the first time, updating the BIOS is not just a recommendation to resolve compatibility or stability issues, but a mandatory security measure to continue playing. Riot Games sets a precedent by directly linking the integrity of the user's hardware to access to their service, underscoring the growing importance of firmware-level security in the gaming ecosystem. 🎮
