CWE-ID:
CWE-122
Exploitation vector: Local
Exploit availability: No
Vulnerable software:
Linux kernel
Operating systems & Components /
Operating system
Vendor: Linux Foundation
Description
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Integer overflow in drivers/gpu/drm/i915/i915_gem_execbuffer.c in the i915 driver in the Direct Rendering Manager (DRM) subsystem in the Linux kernel through 3.8.3, as used in Google Chrome OS before 25.0.1364.173 and other products,. A remote attacker can use a crafted application that triggers many relocation copies to trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
Mitigation
