    "summary": "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.",
