Numerous vulnerabilities in AMD processors

mardi 13 mars 2018, 19:30 , par LWN.net
A company called CTS has disclosed a long
series of vulnerabilities in AMD processors. 'The chipset is a
central component on Ryzen and Ryzen Pro workstations: it links the
processor with hardware devices such as WiFi and network cards, making it
an ideal target for malicious actors. The Ryzen chipset is currently being
shipped with exploitable backdoors that could let attackers inject
malicious code into the chip, providing them with a safe haven to operate
from.' See the associated
white paper for more details.

Update: there are a lot of questions circulating about the actual
severity of these vulnerabilities and the motivations of the people
reporting them. It may not be time to panic quite yet.
