Downfall.page is Daniel Moghimi’s public disclosure page for the Intel processor vulnerability CVE-2022-40982. The vulnerability is known as Downfall. At its core, it involves the possibility that the Gather instruction in Intel processors may leak the contents of internal vector registers during speculative execution, allowing untrusted software to access sensitive data from other programs, users, virtual machines, or even SGX environments. The page explicitly states that the attack can be used to steal data such as passwords, encryption keys, banking information, emails, and messages.
From a cybersecurity perspective, it is closer to a vulnerability intelligence and research resource than a protection product. The page covers GDS and GVI attack techniques, an AES key extraction demo, a Linux Kernel arbitrary data theft demo, and the scope of affected devices: Intel Core processors from 6th-generation Skylake to 11th-generation Tiger Lake. Deployment does not involve installing software; instead, remediation depends on Intel microcode updates and advisories from operating system vendors, cloud providers, and hardware vendors. In terms of management and alerting, the page notes that the attack behavior looks very similar to normal programs, so off-the-shelf antivirus software cannot detect it. In theory, abnormal behaviors such as cache misses could be identified through hardware performance counters.
The page does not provide any commercial pricing, subscription plans, payment methods, or enterprise service descriptions. Its main content consists of public research, paper references, PoC links, and an index of vendor advisories.
The advantages are that the information is centralized, the technical explanation is clear, and it links to multiple advisories from Intel, Debian, AWS, Red Hat, VMware, Ubuntu, and others, making it easier for security teams to verify impact scope and patch status. It also clearly states that cloud multi-tenancy, user-space/kernel-space isolation, and Intel SGX may all be affected. The drawbacks are that it lacks automated asset discovery, patch orchestration, risk scoring, alert integrations, and technical support, so it cannot replace a vulnerability management platform or EDR.
It is suitable for security researchers, vulnerability response teams, cloud platform and data center operations staff, enterprise security architects, and organizations that need to assess Intel CPU side-channel risks.
The captured text does not indicate accessibility in mainland China, so the status is unknown.
