We have seen these exploited in the past. Just because something is a race and hard for us to test (absent TSAN) that doesn't stop an attacker from running that race over and over until they "win" -- no skin off their noses, it's the victim's CPU doing the work. -Dan Veditz _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
