CVE-2021-47645

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

media: staging: media: zoran: calculate the right buffer number for zoran_reap_stat_com

On the case tmp_dcim=1, the index of buffer is miscalculated. This generate a NULL pointer dereference later.

So let's fix the calcul and add a check to prevent this to reappear.
