Intel recently published an advisory concerning vulnerabilities affecting 10th and 11th gen Intel CPUs.
Additionally, it is up to each vendor to publish a BIOS update to address this flaw.
Is there any information as to whether this affects the Librem 14 and Librem Mini?
Purism regularly updates it’s Coreboot, which AFAIK includes the microcode: https://source.puri.sm/firmware/utility.
There’s no enough info in that advisory for me to say with complete certainty, but it appears:
- to not be microcode related
- to be an issue with Intel’s UEFI reference code provided to IBVs/OEMs
Which would heavily point towards it not being an issue with Purism’s coreboot-based firmware
