Joanna Rutkowska's blog points to recent paper on a survey of the various problems and attacks presented against the x86 platform over the last 10 years. The paper does not present new exploits but does cover: the BIOS (UEFI) and booting; peripherals; the Intel Management Engine; and several other aspects of x86 insecurity. Some of the problems appear insurmountable as described.

They use "x86" not as the name of the CPU, but as the name of the platform.
Indeed they explicitly note that the CPU provides everything needed to make an OS secure, but that the existing operating systems don't make use of that.
