CVE-2018-13406
Publication date 6 July 2018
Last updated 24 July 2024
Ubuntu priority
Cvss 3 Severity Score
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.
From the Ubuntu Security Team
Silvio Cesare discovered that the generic VESA frame buffer driver in the Linux kernel contained an integer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
