What is CVE-2008-3831?
CVE-2008-3831 is a medium-severity memory corruption vulnerability in Linux kernel, published on 20 Oct 2008. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The i915 driver in (1) drivers/char/drm/i915_dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and (2) sys/dev/pci/drm/i915_drv.c in OpenBSD does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration.
