PCIe IDE mitigation guidance (CERT/CC)
Advisory/Mitigation
Summary
Hide ▲
Show ▼
CERT/CC issued mitigation guidance for PCIe IDE implementations, urging manufacturers to follow PCIe 6.0 and Erratum #1 to reduce exposure in affected components and firmware. The advice matters because the disclosed IDE flaws can lead to information disclosure, privilege escalation, or denial of service in impacted systems. End users were also told to apply firmware updates from their system or component suppliers.

Riot Games researchers Nick Peterson and Mohamed Al-Sharifi disclosed a UEFI firmware flaw affecting some ASUS, Gigabyte, MSI, and ASRock motherboards and worked with CERT Taiwan to coordinate response and reach affected vendors. The issue can let a malicious PCIe device with physical access exploit an early-boot window where firmware asserts that DMA protections are active even if IOMMU did not initialize correctly, leaving RAM exposed before operating-system safeguards load. Carnegie Mellon CERT/CC confirmed broad motherboard impact, vendors have firmware updates for impacted models, and affected systems may block Valorant from launching through Vanguard.
