Earlier this year, in 2018, some Intel processors found a vulnerability that allowed attackers to steal user data, which was processed on the processor. Immediately the representatives of Intel said that they will work in "patches", that will correct the omission. However, it was recently announced that not all processors could be safe.
According to Intel, the owners of Sandy Bridge and the newer systems will receive the promised updates of the vulnerabilities discovered at the beginning of the Meltdown and Specter year, but the creation of patches for processors of more than seven years is not expected. It is worth remembering that Meltdown and Specter achieved not only Intel chips, but also some AMD products. For the time being, Intel has already released patches for the Broadwell, Haswell, Skylake, Kaby Lake and Coffee Lake models. But the 45-nanometer Core chips of the first and second generation will no longer be updated. Previously, they received some corrections, but there are more corrections that can not wait. This course change Intel explains it in the following way:
"Most old products are implemented as closed systems and are therefore less vulnerable to detected vulnerabilities, and the restriction on the publication of software updates is due to the fact that the Specter infection it is unlikely due to the microarchitectural characteristics of the old chips."
