January 28, 20206 yr Author New Intel vulnerability found dubbed "Cache Out": https://www.pcworld.com/article/3516302/new-cacheout-attack-targets-intel-processors-with-a-fix-arriving-soon.html Intel Processors affected (Intel CPU Skylake/Cascade Lake onward. Broadwell and earlier are seemingly not affected). AMD seemingly not affected: https://software.intel.com/security-software-guidance/insights/processors-affected-l1d-eviction-sampling No mitigation created yet, so time will tell how it's addressed.

July 18, 20214 yr Installed it and using it. But take care: by using a webbrowser (in a VM too) it's possible to leak senstive data. Javascript attacks do exist. Browsers have their own prevention mechanisms, which might not be enough in every case. Edited July 18, 20214 yr by duketwo

Browsers have their own prevention mechanisms, which might not be enough in every case. can you give an example where such VM Browser Leak is / was exploited and what data is being compromised (random temporary host dram bits / cpu cache fragments?) ? Is that really a serious threat with a modern and updated browser I must worry ?
September 25, 20232 yr Is this still valid given newer kernels and if so (I'd be using it) is it also worth me downgrading my BIOS to match?? I assume cos there is nothing I need in F5 I could safely go to F3 and use this Plugin to restore my performance???

September 25, 20232 yr Depends on which vulnerabilities your CPU is affected with. The plugin will tell you that tho. For bios, it depends. If you're affected by specter, 2019 bios will mostly have the fix in it.

Or are you telling me that BIOS mitigations DONT cost performance? If by going back from F5 to F3 (see above) I avoid two BIOS fixes I should (at the cost of security) regain a few %%% performance

But in case of spectre anything from i would say, mid to late 2018 till now certainly will have the fix so you would need an even older bios. thats what i meant.
