kernel: denial of service

A vulnerability has been fixed in Kernel, which can be exploited by malicious people to crash kernel due to divide by zero in azx_position_ok. Using mp3blaster-3.2.5 (latest version) to play MP3 audio, the reporter was able to crash the kernel by stopping and restarting playback using the "5" key repeatedly. This happens as a normal user, not only as root.
