  AMD "INCEPTION" CPU Vulnerability Disclosed
  https://www.phoronix.com/news/AMD-INCEPTION
  ( elméletileg erre a javításra is lesz Phoronix-es benchmark, meglátjuk ... )

  AMD's statement to Phoronix on the matter is:
  "AMD has received an external report titled ‘INCEPTION’, describing a new speculative side channel attack. AMD believes ‘Inception’ is only potentially exploitable locally, such as via downloaded malware, and recommends customers employ security best practices, including running up-to-date software and malware detection tools. AMD is not aware of any exploit of ‘Inception’ outside the research environment, at this time.
  
  AMD recommends customers apply a µcode patch or BIOS update as applicable for products based on “Zen 3” and “Zen 4” CPU architectures. No µcode patch or BIOS update is necessary for products based on “Zen” or “Zen 2” CPU architectures because these architectures are already designed to flush branch type predictions from the branch predictor.
  
  AMD plans to release updated AGESA™ versions to Original Equipment Manufacturers (OEMs), Original Design Manufacturers (ODMs) and motherboard manufacturers listed in the AMD security bulletin. Please refer to your OEM, ODM or motherboard manufacturer for a BIOS update specific to your product.
