An integer overflow in the uvesafb_setcmap function in drivers/video/fbdev/uvesafb.c in the Linux kernel before 4.17.4 could result in local attackers being able to crash the kernel or potentially elevate privileges because kmalloc_array is not used. Un desbordamiento de enteros en la función uvesafb_setcmap en drivers/video/fbdev/uvesafb.c en el kernel de Linux en versiones anteriores a la 4.17.4 podría resultar en que los atacantes locales puedan cerrar inesperadamente el kernel o elevar privilegios debido a que no se emplea kmalloc_array. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9f645bcc566a1e9f921bdae7528a01ced5bc3713 http://www.securityfocus.com/bid/104685 http://www.securitytracker.com/id/1041355 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.17.4 https://github.com/torvalds/linux/commit/9f645bcc566a1e9f921bdae7528a01ced5bc3713 https://lists.debian.org/debian-lts-announce/2019/03/msg00017.html https://usn.ubuntu.com/3752-1 https://usn.ubuntu.com/3752-2 https://usn.ubuntu.com& • CWE-190: Integer Overflow or Wraparound •
