Seriously VU, stop breaking everything. You know what’s better than microarchitectural attacks? IC-enhanced microarchitectural attacks. This work exploits the mechanics of a GPU cache eviction to throw shade on side-channel and rowhammer mitigations, rendering the defenses useless. Demonstration is provided with a remote GPU-enhanced exploit, combining a side-channel and rowhammer attack to compromise an ARM mobile device from the browser.
