Descriptions
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.
La función udl_fb_mmap en drivers/gpu/drm/udl/udl_fb.c en el kernel de Linux en su versión 3.4 y hasta e incluyendo la versión 4.15 tiene una vulnerabilidad de desbordamiento de enteros que permite que usuarios locales con acceso al controlador udldrmfb obtengan permisos totales de lectura y escritura en páginas físicas del kernel, lo que resulta en la ejecución de código en el espacio del kernel.
A an integer overflow vulnerability was discovered in the Linux kernel, from version 3.4 through 4.15, in the drivers/gpu/drm/udl/udl_fb.c:udl_fb_mmap() function. An attacker with access to the udldrmfb driver could exploit this to obtain full read and write permissions on kernel physical pages, resulting in a code execution in kernel space.
