Description
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.

• linux linux kernel (< 5.10.110)
• linux linux kernel (>= 5.11 < 5.15.33)
• linux linux kernel (>= 5.16 < 5.16.19)
