TL;DR
Recent reports claimed Riot’s Vanguard anti-cheat was bricking PCs, but Riot has clarified it does not damage hardware or software. The controversy centers on claims of hardware failures linked to Vanguard updates.
Riot Games has officially clarified that its Vanguard anti-cheat system does not brick or damage PCs, countering recent claims that updates to Vanguard have caused hardware failures or bricked devices.
On May 22, 2026, Riot issued a tweet confirming that Vanguard does not in any way brick PCs or PC components. This clarification follows widespread reports on social media, particularly on Reddit, alleging that a recent Vanguard update had caused hardware issues, including bricked devices and corrupted DMA firmware.
Some users claimed that Vanguard’s latest update was triggering IOMMU restart warnings, which allegedly rendered DMA firmware unusable even after uninstalling Vanguard or without running the game. These reports suggested that the only fix was a complete OS reinstall. However, Riot emphasized that these claims are false and clarified that the image circulating was of cheat hardware devices, not PC components. For more on how anti-cheat systems work, see this detailed explanation.
Riot explained that Vanguard’s recent update has made cheat hardware devices worthless but does not impact the actual hardware or software of players’ PCs. The company highlighted that disabling IOMMU can allow cheat devices to function again, but this does not mean the PC is damaged. Riot reaffirmed its commitment to protecting game integrity while maintaining transparency about its anti-cheat system.
Why It Matters
This development is significant because it addresses widespread concerns about potential hardware damage caused by anti-cheat updates. False claims of bricked PCs can cause panic among players and damage trust in Riot’s anti-cheat measures. Riot’s clarification aims to dispel misinformation and reassure the gaming community that their hardware remains safe. Learn more about how anti-cheat updates impact hardware security.
Understanding that Vanguard does not harm hardware is crucial for players who rely on its security features, especially given the kernel-level access it requires. The controversy also highlights ongoing tensions between anti-cheat measures and user hardware concerns, which Riot is now attempting to resolve through transparency.

Background
Vanguard has been a controversial component since its launch, with players raising concerns about its kernel-level operation and potential hardware impacts. Allegations of bricking devices emerged after updates to Vanguard, with some claiming that their hardware, particularly DMA firmware used for cheat devices, was rendered unusable.
Riot has previously faced criticism for the intrusive nature of Vanguard, which operates at a deep OS level to prevent cheating. The recent claims about hardware damage followed similar reports during Vanguard’s deployment in League of Legends in 2024, though no official confirmation of hardware damage has ever been provided by Riot prior to now.
The company’s latest statement aims to clarify these issues amid ongoing misinformation, emphasizing that the hardware failures reported are linked to cheat devices and not the anti-cheat system itself. For more on Riot’s approach to combating cheating, visit this resource.
