seem to be getting weaponized. This item discusses using known shared code pages from one VM to \u00a0another to force memory corruption using the ‘DRAM hammer’ bit flipping attack modes that have already been well documented as a way to inject hostile code into another (probably all given dedup designs) VM on the same physical machine. This would seem to be a very scary attack for cloud hosting companies.<\/p>\n

It would seem like this is the time for DRAM vendors to take a close look at their designs and start making serious attempts to implement resistance to this sort of attack. I do wonder whether ECC would prevent this as the bit error might be corrected before another error could be introduced.<\/p>\n
