Academics and private sector researchers have revealed details today about three new vulnerabilities affecting Intel CPUs.
All three are Spectre-class attacks that take advantage of a CPU design feature named speculative execution —a feature found in all modern CPUs that has the role of improving performance by computing operations in advance and later discarding unneeded data.
Note: Only Intel CPUs are affected. See
