Hardware check
- Hardware support (CPU microcode) for mitigation techniques
- Indirect Branch Restricted Speculation (IBRS)
- SPEC_CTRL MSR is available: NO
- CPU indicates IBRS capability: NO
- CPU indicates preferring IBRS always-on: NO
- CPU indicates preferring IBRS over retpoline: NO

- Speculative Store Bypass Disable (SSBD)
- CPU indicates SSBD capability: NO
- CPU explicitly indicates not being vulnerable to Variant 4 (SSB_NO): NO
- CPU microcode is known to cause stability problems: NO (model 0x6 family 0x10 stepping 0x3 ucode 0x10000c8 cpuid 0x100f63)
- CPU vulnerability to the speculative execution attack variants

- Kernel has array_index_mask_nospec (x86): NO
- Kernel has the Red Hat/Ubuntu patch: YES
- Kernel has mask_nospec64 (arm): NO
STATUS: NOT VULNERABLE (Mitigation: Load fences)
CVE-2017-5715 [branch target injection] aka ‘Spectre Variant 2’
- Mitigated according to the /sys interface: YES (Mitigation: IBP disabled)
- Mitigation 1
- Kernel is compiled with IBRS support: YES
- IBRS enabled and active: YES (for both kernel and user space)
- Kernel is compiled with IBPB support: YES
- IBPB enabled and active: YES
- Mitigation 2
- Kernel has branch predictor hardening (arm): NO
- Kernel compiled with retpoline option: YES
- Retpoline is enabled: NO
STATUS: NOT VULNERABLE (IBRS + IBPB are mitigating the vulnerability)

- Mitigated according to the /sys interface: YES (Not affected)
- Kernel supports speculation store bypass: YES (found in /proc/self/status)
STATUS: NOT VULNERABLE (your CPU vendor reported your CPU model as not vulnerable)
A false sense of security is worse than no security at all, see --disclaimer
A procesor mam bardzo słaby i jeszcze 8 GB RAM i mam lekkie przycięcia jedynie na przeglądarce firefox,jak mam kilka kart z yt i flash.Na chromium albo operze wszystko płynne
[kasmir@dhcppc0 ~]$ rpm --query centos-release
centos-release-7-5.1804.el7.centos.2.x86_64
To może sobie zmień system z Ubuntu na ten co ja mam,bo u mnie mimo słabego CPU wszystko bardzo płynnie chodzi po za tym przypadkiem co wymieniłem
- może po prostu spróbuj tak zrobić dla próby, będziesz wiedział czy to w tym jest problem.
