Intel tau tshaj tawm cov ntaub ntawv hais txog chav kawm tshiab ntawm qhov tsis zoo hauv nws cov txheej txheem - MDS (Microarchitectural Data Sampling). Zoo li yav dhau los Spectre tawm tsam, cov teeb meem tshiab tuaj yeem ua rau cov ntaub ntawv muaj tswv yim los ntawm kev ua haujlwm, cov tshuab virtual, thiab cov txheej txheem txawv teb chaws. Nws raug liam tias cov teeb meem tau pom thawj zaug los ntawm Intel cov neeg ua haujlwm thiab cov neeg koom tes thaum lub sijhawm tshawb xyuas sab hauv. Thaum Lub Rau Hli thiab Lub Yim Hli 2018, cov ntaub ntawv hais txog teeb meem kuj tau muab rau Intel los ntawm cov kws tshawb fawb ywj pheej, tom qab ntawd yuav luag ib xyoos ntawm kev ua haujlwm sib koom ua ke nrog cov tuam txhab thiab cov neeg tsim khoom lag luam txhawm rau txheeb xyuas qhov muaj peev xwm tawm tsam vectors thiab xa cov kev txhim kho. AMD thiab ARM processors tsis cuam tshuam los ntawm qhov teeb meem.
Txheeb xyuas qhov tsis zoo:
CVE-2018-12126 - MSBDS (Microarchitectural Store Buffer Data Sampling), rov qab cov ntsiab lus ntawm cov khoom khaws cia. Siv rau hauv Fallout nres. Qib ntawm kev txaus ntshai yog txiav txim siab yog 6.5 ntsiab lus (CVSS);
CVE-2018-12127 - MLPDS (Microarchitectural Load Port Data Sampling), rov qab cov ntaub ntawv chaw nres nkoj. Siv nyob rau hauv RIDL nres. CVSS 6.5;
CVE-2018-12130 - MFBDS (Microarchitectural Fill Buffer Data Sampling), rov qab cov ntsiab lus tsis txaus. Siv hauv ZombieLoad thiab RIDL tawm tsam. CVSS 6.5;
CVE-2019-11091 - MDSUM (Microarchitectural Data Sampling Uncacheable Memory), rov qab cov ntsiab lus tsis nco qab. Siv nyob rau hauv RIDL nres. CVSS 3.8.
