The latest Intel CPU exploit termed Zombieload is a speculative execution side-channel attack. It uses Intel Hyperthreading to execute a Microarchitectural Data Sampling (MDS) attack which targets buffers in CPU microarchitecture.
According to a report, Intel CPUs made since 2008 are all susceptible to this attack. The latest 8th and 9th gen Intel CPUs are safe from this issue. Intel has released a security patch for this security flaw.
