    General

    I'm amazed at Intel's ability to downplay the severity of published vulnerabilities. They described CVE-2018-3640 (Rogue System Register Read) as simply an ASLR bypass, but this vulnerability in fact allows the CPU internal CRBUS to be read (at least for Goldmont/Plus uarch) https://t.co/PPdQoRe1bo

    Post summary

    The tweet criticizes Intel for downplaying CVE-2018-3640, stating it allows reading the CPU internal CRBUS on Goldmont/Plus processors.
