  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-50160
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.

Summary
  • (es) 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.
