ASUS Update on Speculative Execution and Indirect Branch Prediction Side Channel Analysis Method

    ASUS is aware of recent security research disclosing software analysis methods known as Meltdown and Spectre that, when used for malicious purposes, have the potential to improperly gather sensitive data from computing devices that are operating as designed. ASUS is working closely with platform owners and OS partners to provide solutions.


    Symptom Description

    Malicious code utilizing a new method of side channel analysis and running locally on a normally operating platform has the potential to allow the inference of data values from memory. The use of this method might facilitate access to unauthorized information to an attacker with local user access.
    The following Intel-based platforms are impacted by this issue, and the list may be modified based on the updates from platform owners at a later time.

    • 2nd generation Intel®Core™ processors
    • 3rd generation Intel®Core™ processors
    • 4th generation Intel®Core™ processors
    • 5th generation Intel®Core™ processors
    • 6th generation Intel®Core™ processors
    • 7th generation Intel®Core™ processors
    • 8th generation Intel®Core™ processors
    • Intel®Atom™ Processor Z Series
    • Intel®Celeron®Processor J Series
    • Intel®Celeron®Processor N Series
    • Intel®Pentium®Processor J Series
    • Intel®Pentium®Processor N Series
