Quick Emulator(Qemu) built with the peripheral timer block for ARM A9MP emulator support is vulnerable to an infinite loop issue. It could occur while updating the a9gtimer in 'a9_gtimer_update'. A privileged user inside guest could use this flaw to consume excessive CPU cycles on the host resulting in DoS.
