CVE-2018-8781

Priority
Description
The udl_fb_mmap function in drivers/gpu/drm/udl/udl_fb.c at the Linux
kernel version 3.4 and up to and including 4.15 has an integer-overflow
vulnerability allowing local users with access to the udldrmfb driver to
obtain full read and write permissions on kernel physical pages, resulting
in a code execution in kernel space.
Ubuntu-Description
Eyal Itkin discovered that the USB displaylink video adapter driver in the
Linux kernel did not properly validate mmap offsets sent from userspace. A
local attacker could use this to expose sensitive information (kernel
memory) or possibly execute arbitrary code.
