Intel Broadwell and Haswell CPUs Experiencing Reboots After Firmware Updates

The company now says that while it thinks that GPZ Variant 2 is hard to exploit on its chips, it'll still work with its partners to release microcode updates and OS patches to mitigate the vulnerability.

By December, the company was done rolling our protections against all three variants.

Intel has warned that its fixes for the Meltdown and Spectre security vulnerabilities rushed out this week may inadvertently have made customers' PCs and servers less stable.

Sadly, not all Chromebooks will get the software updates that would protect them from potential attacks carried out by taking advantage of the Spectre and Meltdown vulnerabilities. The spooky nicknames just add to the drama of this entire event.

Meltdown and Spectre have been discovered in computer chips in billions of computers, smartphone and tablets across the world.

Vendors across the industry have been scrambling to issue proper fixes, but the rollout has been far from ideal. The performance impact of this was significant.

That solution caused "no perceptible impact in our cloud and required no customer downtime", Google states. Google's initial investigations suggested the only way to mitigate Spectre Variant 2 was to disable the CPU performance-optimizing features it targeted. For a time, the team believed the only way to protect against this exploit was to shut down speculative execution, the chip technique that was responsible for the problem.

In the letter Krzanich thanked Google Project Zero for revealing the issues in a responsible manner, and also pledged that the company would increase industry and academic research into security and improve disclosure of security issues.

In doing so, Google turned to one of its engineers who worked as part of the company's Technical Infrastructure group.

Earlier today, Intel announced it discovered some performance hits after implementing its own mitigation solutions at the chip level. On Windows 7 with 6th gen chips the decline is comparable to newer chips on Windows 10. Intel's stock has taken a big hit since the announcement, in spite of the fact these issues affect nearly all modern chips.

As companies are trying to recover from what were, and still are, perhaps the most severe CPU bugs in the history of the computer, people are wondering how exactly does this affect them.
