I installed intel-microcode, but when I use ./spectre-meltdown-checker.sh I get this
CVE-2018-12127 aka 'RIDL, microarchitectural load port data sampling (MLPDS)' * Mitigated according to the /sys interface: NO (Vulnerable: Clear CPU buffers attempted, no microcode; SMT disabled) * Kernel supports using MD_CLEAR mitigation: YES (found md_clear implementation evidence in kernel image) * Kernel mitigation is enabled and active: NO * SMT is either mitigated or disabled: YES > STATUS: VULNERABLE (Vulnerable: Clear CPU buffers attempted, no microcode; SMT disabled)
How do I fix it ? I can't understand
sudo ./spectre-meltdown-checker.sh | grep 'CPU microcode is' [sudo] password for user: * CPU microcode is known to cause stability problems: NO (model 0x2d family 0x6 stepping 0x7 ucode 0x710 cpuid 0x206d7) * CPU microcode is the latest known available version: NO (latest version is 0x714 dated 2018/05/08 according to builtin MCExtractor DB v112 - 2019/05/22) IBPB is considered as a good addition to retpoline for Variant 2 mitigation, but your CPU microcode doesn't support it > STATUS: VULNERABLE (an up-to-date CPU microcode is needed to mitigate this vulnerability)
but it's latest
sudo apt install intel-microcode Reading package lists... Done Building dependency tree Reading state information... Done intel-microcode is already the newest version (3.20180807a.2~deb9u1).
