video: uvesafb: Fix integer overflow in allocation
cmap->len can get close to INT_MAX/2, allowing for an integer overflow in allocation. This uses kmalloc_array() instead to catch the condition. Reported-by: Dr Silvio Cesare of InfoSect <silvio.cesare@gmail.com> Fixes: 8bdb3a2d7df48 ("uvesafb: the driver core") Cc: stable@vger.kernel.org Signed-off-by: Kees Cook <keescook@chromium.org>
