Spectre requires additional hardware updates (bios/microcode/etc) so it is not relevant at the moment to talk about a patch for spectre.
Thats because CentOS/RHEL and other stable server environments back-port all nessesary patches to their own version. Description The version number is NOT an indication of patch level.
