Security researchers at IOActive have discovered a critical flaw in almost two dozen AMD processor models.
Its thatCPU flawwhich security researchers have managed to exploit.
System Management Mode operates at a higher privilege level than the operating system.
And because of that, any changes made to it are invisible and inaccessible to the OS.
Reinstalling the OS, wiping the storage, orantivirus softwarecannot get rid of it.
Thankfully, ts incredibly difficult to successfully execute this attack.
So while kernel exploits do exist, the threat Sinkclose poses is minimal for the average person.
In response to IOActives investigation, AMD has released alist of vulnerable processors, along with some mitigation tips.
The company is also working on security patches for the affected processors.
