Exploit for Observable Discrepancy in Intel Atom_C

This is a tool for checking the state of software mitigations against Spectre and Meltdown vulnerabilities. It uses the NtQuerySystemInformation API call to report the data as seen by the Windows Kernel. The tool is currently optimized for Microsoft Windows 7-10 and uses the best-working exploit...

New Research Reveals Spectre Vulnerability Persists in Latest AMD and Intel Processors

More than six years after the Spectre security flaw impacting modern CPU processors came to light, new research has found that the latest AMD and Intel processors are still susceptible to speculative execution attacks. The attack, disclosed by ETH Zürich researchers Johannes Wikner and Kaveh...

kernel: Spectre v2 SMT mitigations problem

It was found that the Linux Kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The kernel failed to protect applications that attempted to protect against Spectre v2 leaving them open to attack from other processes...
