Red Hat: SPECTRE Variant 1 scanning tool

As part of Red Hat’s commitment to product security we have developed a tool internally that can be used to scan for variant 1 SPECTRE vulnerabilities. As part of our commitment to the wider user community, we are introducing this tool via this article. […] The tool currently only supports the x86_64 and AArch64 architectures. We do hope to add additional architectures in the future.[…]
