Fixing Zenbleed
The flaws AMD found affect different CPUs (they dont always overlap).
The silver lining here is that the attackers would need to have local access to the vulnerable system.
The full list of affected chips, and the patches, can be found on AMDsadvisorypublished earlier this week.
AMD patched the flaws by issuing a new version of AGESA, the base code for motherboard BIOS.
The new version for Zen 2-based chips also patch Zenbleed.
In total, 32 bugs were for software, impacting different chipset drivers, Wi-Fi, and other components.
The remaining two bugs were software and firmware flaws affecting Thunderbolt.
Of the 20, three are high severity.
