Google Explains Meltdown, Spectre Fix Impact On Cloud Services

Google Explains Meltdown, Spectre Fix Impact On Cloud Services

"We have received reports from a few customers of higher system reboots after applying firmware updates", said Intel. It also maintained that Meltdown isn't applicable to AMD chips at all. After months of trying to find solutions, the company did find a solution for Meltdown and the first variant of Spectre (two of the three vulnerabilities).

"We are working closely with them to correct an issue that paused the distribution of patches for some older AMD processors (AMD Opteron, Athlon and AMD Turion X2 Ultra families) earlier this week", Papermaster wrote". But for now, the fix is only optional. Gamers should focus on the 3DMark results as they showcase the DX11 performance hit that Intel measured.

But Nvidia still has to plug the security hole even if it could affect the performance of its GPUs, as is the case with other fixes for Spectre and Meltdown, though Nvidia hasn't detailed any ramifications the patches may carry. Others, including Epic Games, have posted screen shots, illustrating the computing drain on their systems.

"Things may change, however, if you're doing something more intensive with your computer - like performing a large number of complex calculations, or processing large amounts of data".




In the fallout of the discovery of Spectre and Meltdown, companies have been racing to patch vulnerabilities.

Vendors across the industry have been scrambling to issue proper fixes, but the rollout has been far from flawless. To accelerate the security of the entire industry, we commit to publicly identify significant security vulnerabilities following rules of responsible disclosure and, further, we commit to working with the industry to share hardware innovations that will accelerate industry-level progress in dealing with side-channel attacks.

Given the difficulty of solving it, Google's Project Zero security team made a rare exception to its 90-day disclosure policy, which gives vendors and companies 90 days to solve the problem before it releases details of a vulnerability to the public. "We expect this issue to be corrected shortly and Microsoft should resume updates for these older processors by next week". That report cited an internal Intel document disclosing that the company identified three issues in microcode updates released over the past week meant to address the vulnerabilities. Those updates can be found on Intel's site.
