The Spectre vulnerability is a concern of everyone in recent times. It is reported that AMD will provide microcode update of the Spectre vulnerability this week on the old platform brick problem. AMD said it has been distributed to left and right motherboard manufacturers.
Yesterday AMD updated the "AMD Processor Security Description" column, indicating that AMD has prepared a new patch to deal with the risks brought by the Spectre vulnerability, and at the same time fixed the problem of a large number of AMD old platforms bricking due to the upgrade of the Microsoft system patch.

However, the Spectre vulnerability is not so good, and it has become a big problem for billions of devices around the world. AMD is optimistic about the variant "branch target injection", which is difficult to apply to AMD's processor. Vulnerabilities, but still add additional protection (update microcode, system patches) to reduce potential risks.

In theory, the update service provided on the Ruilong/EPYC motherboard should be seen this week, and the old platform product update will arrive next week. The whole update speed depends on For related manufacturers.
MSI, Gigabyte and other vendors have reacted relatively quickly and have provided consumers with the latest BIOS, but brushing the BIOS is a relatively difficult operation.
For the "bypass boundary check" vulnerability, AMD also said that the first big, the last system cooperation with Microsoft company patch appeared "overturn", AMD Opteron, Athlon, Turion X2 Ultra series CPU platform update will become brick, and finally emergency withdrawal At the end of the game, both sides have completed the bug check and resumed the patch update. Now they are not afraid to change bricks.
