I would imagine that SME/TME (AMD/Intel memory encryption) would mitigate Rowhammer-style attacks quite effectively because attackers would not be able to control the physical bit patterns anymore?
- guerrilla 5y agoNope. It only requires being able to read neighboring cells. It would make a privilege escalation attack harder but not impossible. DoS attacks would still be relatively easy.
- LogonType10 5y ago>DoS attacks would still be relatively easy. Local DoS? Can you elaborate on this?
- guerrilla 5y agoRowhammer is a memory corruption technique, so if you corrupt the right memory of a process in the right way then you can crash it; same for a kernel or hypervisor.
- 420official 5y agoThey are saying that privilege escalation is harder because it's really challenging to target specific bits to flip, whereas flipping random bits will eventually lead to a crash of some kind causing the service to fail which is effectively a DoS
