| [[Bus_services|sasbus]] StartPeriodicReceiveMode infoleak
 +
| StartPeriodicReceiveMode writes a vtable ptr into the mapped tmem at +0. The tmem is mapped RW in the user-process. There is no clearing of tmem during tmem cleanup. Hence, the user-process can read the tmem to obtain a Bus-sysmodule codebin-region infoleak. This vtable-ptr seems to be unused - it's also empty after the first two entries (stubbed incref/decref).
 +
[20.0.0+] Removed the vtable ptr, with data intended for the user-process being moved from tmem+0x8 to +0x0. Also, instead of calling memset, funcs are called for manually clearing tmem.
 +
| Bus-sysmodule infoleak, which allows defeating ASLR.
