Description
In the Linux kernel, the following vulnerability has been resolved: media: cobalt: Avoid freeing ALSA private data twice snd_cobalt_card_create() stores cobsc in sc->private_data and installs snd_cobalt_card_private_free() as sc->private_free. From that point, snd_card_free(sc) releases cobsc through the ALSA card cleanup path. If cobalt_alsa_init() fails after snd_cobalt_card_create(), the err_exit_free path calls snd_card_free(sc) and then kfree(cobsc). That second free releases the same object again. Remove the explicit kfree(cobsc) and leave ownership with the ALSA card. This issue was found by a static analysis checker and confirmed by manual source review.
