Deskripsi CVE
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.
