Intel microprocessor generations 6 to 8 are affected by a new Spectre
variant that is able to bypass their retpoline mitigation in the kernel to
leak arbitrary data. An attacker with unprivileged user access can hijack
return instructions to achieve arbitrary speculative code execution under
certain microarchitecture-dependent conditions.
