| [[Audio_services|audctl]] GetTargetDeviceInfo infoleak
| audctl GetTargetDeviceInfo calls an impl func with a ptr to a stackbuf, then if successful memcpys the 0x100-bytes from that buffer to output. This stackbuf is not memset. This func (after doing various state checks) copies a string to output, other than always writing a NUL-terminator there's no clearing of the buffer.
This will leak audio-sysmodule stack into the output buffer as long as the state/input checks pass (for the remainder of the buffer following the string NUL-terminator).
With [18.0.0+] data is written directly to the outbuf instead of the stack tmpbuf.
| audio-sysmodule infoleak, which allows defeating ASLR.
