Intel has delivered a stable microcode update for its Broadwell and Haswell processors to mitigate against the Spectre chip flaw.
The company had initially issued firmware updates for machines with its Broadwell, Haswell, Skylake, Kaby Lake, and Coffee Lake processors to address the Spectre/Meltdown chip flaws earlier this year, but was forced to pull the microcode after it caused systems to crash and reboot.
Revised firmware for Skylake, Kaby Lake, and Coffee Lake processors was released last week, but users with Broadwell and Haswell-based machines were left waiting for their own updates.
The updates address variant 2 – the branch injection vulnerability – of the Spectre chip flaw revealed earlier this year.
