The CPU vulnerability is finally eliminated! AMD: BIOS updates for Ryzen and EPYC platforms are released this week. ryzenepyc

Previously, amd cto (Chief Technology Officer) Mark Papermaster updated the AMD processor Security description (Chinese pages are not yet online ).

Specifically, for V1 in the Spectre Vulnerability (bypassing the boundary check), AMD still believes that it can be solved by updating the operating system and software.

Microsoft has now resumed the Update operation after a system startup fault is triggered and patches for the AMD platform are stopped. AMD revealed that the affected platforms include AMD Opteron/Athlon/Turion X2 Ultra.

For Linux, kernel and branch vendors have started to update.

For the V2 (branch target injection) in the Spectre vulnerability, AMD said that although they still believe that it is difficult to implement attacks based on different architecture designs, for the sake of absolute security, update the processor microcode (Editor's note: it will finally be converted to BIOS update ).

Among them, the main board BIOS of Ryzen and EPYC processor platforms will be released one after another this week, and other products will be released in the next few weeks.

For the Meltdown vulnerability, that is, V3 (malicious data cache loading), AMD believes that it is still completely immune and does not require any repair.

However, it is interesting that AMD does not mention whether it will affect performance after patching.
