Intel says newer chips also experience sudden reboots after Meltdown-Spectre fixes

Intel says newer chips also experience sudden reboots after Meltdown-Spectre fixes

Last week, Intel confirmed that only its older Broadwell and Haswell chips were facing unexpected reboots due to the Intel Meltdown and Spectre patch.

The first, called Meltdown, affects Intel chips and lets hackers bypass the hardware barrier between applications run by users and the computer's memory, potentially letting hackers read a computer's memory and steal passwords.

"The firmware updates are effective at mitigating exposure to the security issues, customers have reported more frequent reboots on firmware updated systems". We don't know when an official patch for the problem will be launched, but Intel says it will be delivering microcode to its vendor partners for validation next week.

Over the past several days, Intel has made further progress to address the exploits known as "Spectre" and "Meltdown". "We have now issued firmware updates for 90 percent of Intel CPUs introduced in the past five years", Shenoy says.

Going on two weeks since the reveal of Meltdown and Spectre, are you all patched up?

Last week, AMD put out a security update confirming that its processors are vulnerable to Spectre variant 1, which will be contained by operating system patches.




But Oracle and many other vendors have yet to publish a full list of affected products or a timeline for when users can expect to see patches.

"ARM Holdings PLC, the company that licenses the ARM architecture to Apple, admits that it was notified of the Security Vulnerabilities in June 2017 by Google's Project Zero and that it immediately notified its architecture licensees (presumably, including Apple) who create their own processor designs of the Security Vulnerabilities", says the lawsuit issued by Anthony Bartling and Jacqueline Olson in a United States district court in San Jose. Intel also said that these fixes may cause up to 25% performance impact on certain server workloads.

On Jan. 10, I provided initial performance data results for client systems and today I have initial results to share on the data center side.

Intel issued the update as part of a broader update on the performance impact of the patches on data center workloads.

The post highlights other mitigation options that have less of a performance impact, including Google's "Retpoline" security solution, which is said to have nearly no effect on a system's speed.
