    Köszi a cikkeket, nagyon tanulságos olvasmányok.

    "Spectre affects virtually all out-of-order CPUs that use speculative execution to increase performance, including AMD and Arm’s processors. "

    "AMD CPUs were also impacted by PortSmash, a vulnerability affecting its Simultaneous Multi-Threading (SMT) feature, which is similar to Intel’s Hyper-Threading. AMD processors were also vulnerable to NetSpectre and SplitSpectre, as these vulnerabilities affected processors, that were also vulnerable to Spectre v1. "

    "The AMD Platform Security Processor (PSP), also known as AMD Secure Processor, uses an Arm Cortex-A5 processor to isolate certain chip platform functions from the main processor and the main operating system. It’s similar to AMD’s ME, and just like ME, it can also be potentially exploited to devastating effect if a malicious party finds a bug in it.
    Since 2017, at least three PSP vulnerabilities have been found. A Google security researcher found one in 2017. The bug would have given attackers access to passwords, certificates, and other sensitive information."

    És akkor az amd procik nem sebezhetőek. :Y

    Egyik cikkben sem láttam hogy akármelyik intel sebezhetőség visszanyúlna 1995-re, a legrégebbi dátum ehhez kapcsolódóan 2008. Ennyit erről akkor.
