Planned Nuclear Reactors Will Destroy Atomic Waste 344

separsons writes "A group of French scientists are developing a nuclear reactor that burns up actinides — highly radioactive uranium isotopes. They estimate that 'the volume of high-level nuclear waste produced by all of France’s 58 reactors over the past 40 years could fit in one Olympic-size swimming pool.' And they're not the only ones trying to eliminate atomic waste: Researchers at the University of Texas in Austin are working on a fusion-fission reactor. The reactor destroys waste by firing streams of neutrons at it, reducing atomic waste by up to 99 percent!"

My OS classes kicked back from the past right into my mind... Even as root or it equivalent on any other OS. I think the "right" and polite behavior for root is: "You may kill any process, but you should not be able to modify the content of any process or thread that it is not your own or that you directly spawned". Because this is actually what happens with this exploit. You insert code into the cache, that when executed it does something like jumping into some other code that does the nasty stuff. Right?

Answering myself. If the cache is altered, the CPU should rise a flag saying something has happen. I am not sure how the cache works, but I imagine the cache is a table with the address of the value it has cached in one side, and the actual value on the other. If this is the case, who to blame depends if the compiler has any control over the cache, if the cache is hardwired. Or both!
