Meltdown & Spectre Information and Discussion

[Ottawagrant]

To Searchernow: I have 2 Acer netbooks. Both have the Intel Atom processor, version N455, made in 02/2011. According to an article I read the Intel Atom (made before 2013) is one of only 2 processors unaffected. That's what I read. (humor intentional). I will install LL 3.6 32-bit on it today & run Jerry's test. I'll post the results here as well as the netbook's spec's. Both netbooks have Windows 7 starter on them now, so no loss there.

Thanks Trinidad - I'll update my Win7 laptop AVG free then try the Win check you posted.

Thanks too Ottawa - I since looked at my netbook (Samsung) - it has Atom N450, pretty sure it's pre-2013, and presumably pre - N455.
It's spec is 1.67Ghz and 2gb ram - so comfortably within LL recomended.

Sorry, I meant to add:

tweaktown's list, reportedly an official Intel list, is shown below.
My netbook (32 bit, Win7 Home Prem) doesn't give "series" - just Atom N450, but looking at the Atom wikipedia entry, my date of purchase Feb. 2011, logo sticker etc. then the series is N (obvious now) so appears not to be on the vulnerable list, as you suggest!


from https://www.tweaktown.com/news/60411/her...index.html  "12 days ago"

"Intel has finally released a full list of all of their processors that are open to the Spectre and Meltdown security flaws, with virtually all Intel CPUs at risk.

The chipmaker has worked closely with AMD, ARM Holdings, and multiple operating system makers in order to push an industry-wide approach to fixing this problem.
Intel will soon have an update for 90% of their processors, something that should drop in the next few days.

I reverted to the 4.4.0 available in the Lite Kernels list in Lite Tweaks, as 4.10 is vulnerable, but still get this.
How can I get to the 111 version of Lite 4.4.0 ?

Remove kernel 4.10 and then update kernel 4.4. You must be running on 4.4 to delete 4.10. If you are running 4.4 now try updating. I think LL will only update the running kernel, though not sure. In any case 4.4 in LL will update to -111.

Acer Aspire One netbook D255E
Intel Atom n455 1.66GHz processor
Manufactured 02/2011
Linux Lite 3.6 32-bit
Fresh install on kernel 4.4.0-93 #116
Variant #1 - no
            #2 - yes
            #3 - yes


updated kernel to 4.4.0-111 #134

Variant #1 - no
            #2 - yes
            #3 - yes
A different article that I read seems to suggest that it is the Intel Atom 32-bit only that is OK. It's suggested that any chip that is x86_64 is vulnerable. I installed LL on the netbook with Windows 7 starter, so no loss there. But if anyone wants to try it on a netbook/laptop/desktop without installing LL, just boot into a live environment via USB, download Jerry's zip file, extract, & then double-click the 'sm-start'. No password required. It'll be an older kernel, but it'll give you an idea for your device.

v1 Spectre is partially mitigated against timing attacks, by Firefox 57 and ESR

hello im new to the party.
i have downloaded and installed the latest microcode from the lite repo.is this enough to mitigate.?
my browser is google chrome.

thank you.

Thanks Jerry for the Automated Spectre/Meltdown Checker.

http://news.softpedia.com/news/linux-lit...9431.shtml

Ran the script and my results were the same.

"Spectre Variant 1"  Status: Not Vulnerable

"Spectre Variant 2"  Status: Vulnerable

"Meltdown aka Variant 3"  Status: Not Vulnerable

(Results with latest Intel microcode update and updated Linux kernel 4.4.0-111)

In respect to "Spectre Variant 2"  the following article - Ubuntu Preparing Kernel Updates With IBRS/IBPB For Spectre Mitigation - may be reassuring.
