Descriptions
In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda/cs8409: Fix possible NULL dereference
If snd_hda_gen_add_kctl fails to allocate memory and returns NULL, then
NULL pointer dereference will occur in the next line.
Since dolphin_fixups function is a hda_fixup function which is not supposed
to return any errors, add simple check before dereference, ignore the fail.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: hda/cs8409: Se corrige una posible desreferencia de NULL. Si snd_hda_gen_add_kctl no puede asignar memoria y devuelve NULL, se producirá una desreferencia de puntero NULL en la siguiente línea. Dado que la función dolphin_fixups es una función hda_fixup que no debería devolver ningún error, se debe agregar una comprobación simple antes de la desreferencia e ignorar el error. Encontrado por Linux Verification Center (linuxtesting.org) con SVACE.
