CVE-2008-3831

The i915 driver in 1 drivers/char/drm/i915dma.c in the Linux kernel 2.6.24 on Debian GNU/Linux and 2 sys/dev/pci/drm/i915drv.c in OpenBSD does not restrict the DRMI915HWSADDR ioctl to the Direct Rendering Manager DRM master, which allows local users to cause a denial of service memory corruption...

CVE-2008-3831

The CVE-2008-3831 entry concerns the i915 DRM driver in Linux kernel 2.6.24 (notable on Debian GNU/Linux) and OpenBSD. The root cause is that the DRM_I915_HWS_ADDR ioctl is not restricted to the DRM master due to the absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl configuration. Th...

CVE-2008-2372

The Linux kernel 2.6.24 and 2.6.25 before 2.6.25.9 allows local users to cause a denial of service memory consumption via a large number of calls to the getuserpages function, which lacks a ZEROPAGE optimization and results in allocation of "useless newly zeroed pages."...
