IO Interactive's game, 007: First Light, will include "Denuvo Anti-Tamper" DRM to protect against piracy on PC, leading to customer frustration among pre-order users. The Steam forums show mixed reactions, with some players disappointed and others appreciative of the DRM. Denuvo can impact frame rates and requires significant resources for integration, potentially affecting paying customers' experiences. It has been reported that Denuvo was cracked shortly after the launch of Lego Batman: Legacy of the Dark Knight, raising concerns about its effectiveness. Denuvo operates in user space, not at the kernel level, and players may be locked out if their internet connection fails for over 48 hours. Developers face a paradox, as implementing DRM aims to maximize sales but may disadvantage legitimate customers. Alternative strategies exist, as seen with Cyberpunk 2077, which launched without DRM and became successful. A 2017 European Commission report suggested that piracy might increase overall sales, as some users who initially pirate games later become paying customers.

Valorant's anti-cheat system, Vanguard, has been controversial due to its interference with DMA firmware devices, which are used to cheat in the game. Riot Games posted a message suggesting that Vanguard was making these devices unusable, leading to backlash from the gaming community. Riot clarified that Vanguard does not damage hardware or disable devices but prevents DMA cheat devices from functioning while IOMMU protections are enabled. Players not using DMA devices are not affected. The situation has sparked debate about the balance between anti-cheat measures and their impact on hardware.

Riot Games' Vanguard anti-cheat system, introduced with Valorant and later integrated into League of Legends in 2024, operates at a kernel level, raising concerns about potential damage to players' PCs. Issues arose when streamer Nick 'LS' De Cesare experienced computer problems after a Vanguard update. The latest version of Vanguard reportedly made some cheaters' computers inoperable, requiring a complete operating system reinstall. Players must have Vanguard installed to access Riot's games, and the system now blocks most DMA firmware, which is used to mask cheats. Vanguard can activate even without Valorant installed, and if it detects DMA firmware, the only solution is a Windows reinstall. Riot Games acknowledged the complaints humorously, highlighting the frustrations of affected users. The kernel-level operation of Vanguard raises concerns about the risk of damaging personal computers due to misidentification, and legal discussions about its implications are ongoing. Players who do not want to use Vanguard cannot access Riot's games.

In April 2026, two zero-day vulnerabilities, RedSun and UnDefend, were discovered in Microsoft Defender, affecting Windows 10, Windows 11, and Windows Server platforms. These vulnerabilities allow attackers to escalate privileges to SYSTEM and bypass Defender’s protections. RedSun exploits a flaw in Defender's remediation process, enabling low-privileged users to overwrite critical system files. UnDefend allows attackers to disrupt Defender’s updates, keeping it outdated and ineffective. Both vulnerabilities are actively being exploited, with attackers leveraging them to gain persistent access and deploy ransomware. The primary targets are organizations using Windows systems with Defender enabled, particularly in sectors like finance, healthcare, and government. Mitigation strategies include applying updates for related vulnerabilities, monitoring for suspicious activities, and implementing additional security measures.

NVIDIA has released an update to its GPU display drivers that addresses 14 vulnerabilities across its product lines, including GeForce, RTX, Quadro, Tesla, NVS, vGPU, and Cloud Gaming software. The most critical vulnerability is CVE‑2026‑24187, a high-severity use-after-free bug rated 8.8 out of 10, which could allow code execution, privilege escalation, data theft, or system crashes. Linux systems are vulnerable due to improper access to GPU resources at the kernel level, while Windows systems are at risk from a timing flaw. Two vulnerabilities in NVIDIA’s Unified Virtual Memory subsystem on Linux could lead to denial-of-service attacks without elevated permissions. The vGPU software also received patches for vulnerabilities in its virtual GPU manager component. Users can download the updated drivers from the NVIDIA Driver Downloads page or the NVIDIA Licensing Portal, with Windows users needing version 569.49 or newer and Linux users needing version 590.48.01. Users are advised to maintain their antivirus programs for enhanced security. NVIDIA thanked external security researchers for their responsible disclosure of these vulnerabilities.

Embark has launched an anti-cheat software for the multiplayer game Arc Raiders using Denuvo technology to address issues with wall hacks, aimbots, and other unfair advantages. A trial for a kernel-level anti-cheat system will begin on May 19 with a select group of players, and a broader rollout will follow based on the trial's success. The developers have opted not to use Denuvo DRM to avoid performance issues, prioritizing a seamless gaming experience despite concerns about piracy. Recent cheating allegations have increased, with players, including streamer Tyler 'Ninja' Blevins, expressing frustration over encounters with cheaters. Many players are willing to adjust their settings to ensure fair gameplay, recognizing the challenges posed by cheating.
