  3. CVE-2024-40964
In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: cs35l41: Possible null pointer dereference in cs35l41_hda_unbind() The cs35l41_hda_unbind() function clears the hda_component entry matching it's index and then dereferences the codec pointer held in the first element of the hda_component array, this is an issue when the device index was 0. Instead use the codec pointer stashed in the cs35l41_hda structure as it will still be valid.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: hda: cs35l41: Posible desreferencia del puntero nulo en cs35l41_hda_unbind() La función cs35l41_hda_unbind() borra la entrada hda_component que coincide con su índice y luego desreferencia el puntero del códec contenido en el primer elemento de la matriz hda_component, esto es un problema cuando el índice del dispositivo era 0. En su lugar, utilice el puntero del códec escondido en la estructura cs35l41_hda, ya que seguirá siendo válido.
