Just wondering, does anyone think a ccNuma machine could be exploited in
similar to this fashion? ccNuma is cache coherent non uniform memory
access. I am very loosely (with seriously limited knowledge on the
subject) wondering if the mechanisms that snoop the caches in such
architectures to avoid stale caches could be exploited to look into
places beyond an applications security privelages.
Given these arch's come from high end vendors one would hope not.
