Description
A flaw was found in the Advanced Linux Sound Architecture (ALSA) hda/conexant driver within the Linux kernel. A missing error check for the snd_hda_jack_detect_enable_callback() function's return value in cx_probe() can lead to a kernel crash. If the registration of the jack detection callback fails, the driver may attempt to handle jack events or access an uninitialized structure, resulting in a Denial of Service (DoS).
