Device Driver Buffer Overflow

Another alternative, if you can use kernel 3.5 or newer, might be to use the "Contiguous Memory Allocator" (CMA) -- look at and drivers/base/dma-contiguous.c for more information. These two masters come together to pierce the veil of mystery surrounding rootkits, bringing this information out of the shadows.

I want to do so by using mmap()'s offset parameter, for example (from userspace): mapped_ptr = mmap(NULL, buf_len, PROT_READ | PROT_WRITE, MAP_SHARED, fd, (MAGIC + buffer_id) * PAGE_SIZE); Where "MAGIC" is Find out what it means to be owned by reading Hoglund and Butler's first-of-a-kind book on rootkits. As the only book on the subject, "Rootkits" will be of interest to any Windows security researcher or security programmer.

This vulnerability could be exploited in order to execute arbitrary code on the target system.

Usually, userspace will mmap() about 10..20 buffers at the same time, so it is nice and clean solution for this case. In this book, they reveal never-before-told offensive aspects of rootkit technology--learn how attackers can get in and stay in for years, without detection.
