Title
media: atomisp: prevent integer overflow in sh_css_set_black_frame()
Summary
In the Linux kernel, the following vulnerability has been resolved: media: atomisp: prevent integer overflow in sh_css_set_black_frame() The "height" and "width" values come from the user so the "height * width" multiplication can overflow.
