    This kernel update is based on the upstream 5.3.13 and fixes atleast the 
    following security issues:
    
    Insufficient access control in a subsystem for Intel (R) processor graphics
    may allow an authenticated user to potentially enable escalation of
    privilege via local access (CVE-2019-0155).
    
    TSX Asynchronous Abort condition on some CPUs utilizing speculative
    execution may allow an authenticated user to potentially enable
    information disclosure via a side channel with local access
    (CVE-2019-11135).
    
    Improper invalidation for page table updates by a virtual guest operating
    system for multiple Intel(R) Processors may allow an authenticated user to
    potentially enable denial of service of the host system via local access
    (CVE-2018-12207). 
    
    For proper mitigations and fixes for theese issues, a microcode update is
    also needed, either with a bios/uefi update from your hardware vendor or
    by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688).
    
    For other upstream fixes in this update, see the referenced changelogs.
