Memory leak in the serial_exit_core function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
