Meltdown and Spectre logos

As Intel, AMD, and other CPU manufacturers have started releasing CPU microcode (firmware) updates for processor models affected by the Meltdown and Spectre patches, those updates are trickling down to OEMs and motherboard vendors, who are now integrating these patches into BIOS/UEFI updates for affected PCs.

While not all vendors have patches available for vulnerable products right away, most have promised updates in the following months.

These BIOS/UEFI updates are part of a one-two punch to address the Meltdown and Spectre flaws that came to light at the start of the year.

Software patches at the operating system level have largely mitigated the Meltdown flaw, but both Microsoft and the Linux community said a firmware fix would be necessary to fully address the Spectre vulnerability.

Bleeping Computer users can use the links below to visit the download centers of their respective OEM provider and download BIOS/UEFI updates if their desktop, laptop, or notebook is using a vulnerable CPU and is listed as affected.

We'll try to keep the list up to date as much as possible. If your OEM vendor is not listed, or the download link goes 404 or is updated, don't hesitate to leave us a comment and we'll update the story as soon as possible.
