Hi,
Further to my previous question about the sinkhole attack, I'm also interested in whether this vulnerability affects coreboot systems: http://www.rowhammer.com/
Specifically, in my case, I am interested in the following coreboot systems:
- i945 platforms (Lenovo X60/T60, Macbook2,1)
- GM45 platforms (Lenovo X200/T400/T500/R400/R500)
- fam10h AMD platforms (ASUS KFSN4-DRE, ASUS KGPE-D16)
Could someone shed a light on this?
Regards, Francis Rowe.
This is highly DIMM and controller specific. Basically you need to test your own hardware to know one way or the other.
That being said, even though ECC does not offer much theoretical resistance to this attack, from what I gather servers with ECC have not yet been found vulnerable. It is possible that manufacturers simply chose higher binned chips when assembling the ECC DIMMs, or that some other process variable is different.
Most likely to be affected would be the GM45 platforms in laptops (DDR3, and corner cutting is highly likely in the SO-DIMM format).
