Exploitation Summary
CVE-2013-2596 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added September 15, 2022. EIP tracks 1 public exploit from researchers including hiikezoe.
AI-analyzed exploit summary This exploit leverages a memory mapping vulnerability in the Linux framebuffer driver to achieve arbitrary kernel memory write, enabling local privilege escalation. It maps kernel memory via /dev/graphics/fb0 and manipulates kernel structures to gain elevated privileges.
Description
Integer overflow in the fb_mmap function in drivers/video/fbmem.c in the Linux kernel before 3.8.9, as used in a certain Motorola build of Android 4.1.2 and other products, allows local users to create a read-write memory mapping for the entirety of kernel memory, and consequently gain privileges, via crafted /dev/graphics/fb0 mmap2 system calls, as demonstrated by the Motochopper pwn program.
