An urgent pull request was sent out this weekend,to extend the Linux 6.5 kernel’s AMD Zenbleed vulnerability mitigation to Valve’s Steam Deck. It turns out that when the kernel was patched last month, mitigations weren’t implemented for Valve’s custom AMD SoC, sometimes known as Aerith, Phoronix first reported.
AMD’s Zen 2 product stack is pretty complicated, so it is hard to be critical of the Linux dev team. Zen 2 cores debuted with the well-known Ryzen 3000 chips, but the Zen 2 architecture can be also found in some Ryzen 4000 and 5000 processors, as well as Epyc server chips, the Sony PlayStation 5, in the Microsoft Xbox Series X/S consoles, and Valve’s Steam Deck.
