We needed to turn this 8-byte write vulnerability into something useful for an attacker. This is important because it means we can use the 8-byte write primitive to corrupt and control its value. Any VR application can trigger this vulnerability by sending a specially crafted SetPerformanceIdealFeatureState Runtime IPC message.

We paid particular attention to deallocation of direct byte buffers, but we haven’t seen any impact thus far. Except in a couple of cases, there’s been no need to lower the maximum heap size to allow for more headroom, and those were services with greater than average native memory needs.
