Motherboard vendors release BIOS updates for Spectre
Gigabyte has joined the list of vendors offering BIOS updates to address Spectre vulnerabilities
BIOS updates to address the Spectre vulnerability have begun rolling out from the major motherboard original equipment manufacturers (OEMs).
Patches and updates for Meltdown/Spectre vulnerabilities continue to trickle in.
When the issue first broke, Intel said that CPU microcode (BIOS) updates would be required in addition to software patches. The chip maker later said it had released the updates, but it wasn't clear in what form users would receive them nor what vulnerability they were for. AMD, being invulnerable to Meltdown, said that it was still vulnerable to one of the vulnerabilities in Spectre, but it had not issued any updates.
Only Variant 2, one of the two vulnerabilities that make up Spectre, requires a CPU microcode update. Variant 2 is also the vulnerability that AMD has said it is most likely not vulnerable to, thus the company has not issued any updates.
The only required BIOS updates are to address Variant 2 for Intel CPUs. If your Intel machine is from a system OEM, look for the updates to come from that manufacturer, most of which are linked here.
Do it yourself (DIY) system builders are, as usual, left waiting for motherboard OEMs to release updates.
To that end, the first few are beginning to come in. Asus was the first to address the issue. MSI has also just released its first updates.
