Specter, Meltdown vulnerabilities recently made Intel a lot of trouble, because in recent years the products exist in groups, need to be repaired one by one, the workload is really rare, but also during the frequent reboot after patching phenomenon. Prior to this, Intel has pushed the two flaws in the repair patch to the 6th generation of Corel Skylake, 7th-generations of Core Kaby Lake, 8th-generation to solve the frequent restart problem.
Specter bugs are actually two versions, CVE-2017-5715 can be resolved through software updates, CVE-2017-5053 you must be hardware-level repair, seven generations of Core Duo has been completed.
Now Intel has released a patch for the second generation of Specter vulnerabilities to the fourth generation of Core Haswell and the fifth generation of the Broadwell family, emphasizing a stable patch, that is, it should not cause a restart.
Haswell first released in 2013, the following year conducted a speed upgrade, so the product is particularly large.
Broadwell is the product of 2015, but most are mobile platforms, only two on the desktop, so the impact is relatively small.
