My understanding was that a CPU microcode update is stored in non-volatile memory on the motherboard and is loaded by the BIOS or UEFI into volatile memory on the CPU during boot. And because the ...
Last month, a team of Google security researchers released a tool that can modify microcode of AMD's processors based on the Zen microarchitecture, the Zentool. While this is a security vulnerability, ...
On January 8th Intel released new Linux Processor microcode data files that can be used to mitigate the Spectre and and Meltdown vulnerabilities in Intel CPUs. Using microcode files, an operating ...
In a nutshell: Google researchers recently disclosed a stealthy security flaw dubbed "EntrySign" that allowed malicious code execution through unsigned microcode patches on AMD processors from Zen 1 ...
Something to look forward to: Intel's plan to address voltage-related crashes on desktop processors with a patch has some worried that performance and overclocking will take a hit. Past updates to ...
A team of Google researchers working with AMD recently discovered a major CPU exploit on Zen-based processors. The exploit allows anyone with local admin privileges to write and push custom microcode ...
Microsoft has released a new batch of Intel microcode updates for Windows 10 20H2, 2004, 1909, and older versions to fix new hardware vulnerabilities discovered in Intel CPUs. When Intel finds bugs in ...
