CVE-2023-53748

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

media: mediatek: vcodec: Fix potential array out-of-bounds in decoder queue_setup

variable *nplanes is provided by user via system call argument. The
possible value of q_data->fmt->num_planes is 1-3, while the value
of *nplanes can be 1-8. The array access by index i can cause array
out-of-bounds.

Fix this bug by checking *nplanes against the array size.
