Cfir Cohen, a security researcher from Google's cloud security team, on Wednesday disclosed a vulnerability in the fTMP of AMD's Platform Security Processor (PSP), which resides on its 64-bit x86 processors and provides administrative functions similar to the Management Engine in Intel chipsets.
Cohen said he reported the flaw to AMD in late September last year, and the biz apparently had a fix ready by December 7. Now that the 90-day disclosure window has passed seemingly without any action by AMD, details about the flaw have been made public.
