The problem is this code from ap1302_enum_frame_size():
738 int index = fse->index;
739
740 mutex_lock(&dev->input_lock);
741 context = ap1302_get_context(sd);
742 if (index >= dev->cntx_res[context].res_num) {
743 mutex_unlock(&dev->input_lock);
744 return -EINVAL;
745 }
746
747 res_table = dev->cntx_res[context].res_table;
748 fse->min_width = res_table[index].width;
"fse->index" is a u32 that come from the user. We want negative values
of "index" to be treated as -EINVAL but they're not so we can read from
before the start of the res_table[] array.
I've fixed this by making "res_num" a u32. I made "cur_res" a u32 as
well, just for consistency.
Fixes:
