Descriptions

Multiple integer overflows in Alchemy LCD frame-buffer drivers in the Linux kernel before 3.12 allow local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted mmap operations, related to the (1) au1100fb_fb_mmap function in drivers/video/au1100fb.c and the (2) au1200fb_fb_mmap function in drivers/video/au1200fb.c.

Múltiples desbordamientos de enteros en drivers frame-buffer en Alchemy LCD del kernel de Linux anterior a la versión 3.12 permite a usuarios locales crear y leer-escribir asignación de memoria para la totalidad de memoria del kernel, y consecuentemente obtener privilegios a través de operaciones manipuladas mmap, relacionadas con (1) au1100fb_fb_mmap function en drivers/video/au1100fb.c y (2) au1200fb_fb_mmap function en drivers/video/au1200fb.c.
