Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument.

Security readout for executives and security teams

CVE-2011-1013 is an old local kernel flaw in the DRM graphics subsystem. A user already able to run code on an affected Linux or OpenBSD system could crash the machine, with sources also noting possible unspecified additional impact. Exposure is most likely on legacy Linux kernels before 2.6.38 or OpenBSD systems before 4.9, especially systems allowing untrusted local users or workloads. Modern supported distributions are less likely affected, but vendor backports must be checked. Treat this as a legacy exposure cleanup item unless unsupported multi-user systems remain in service. Business risk rises where untrusted users can run local code, because a crash can affect availability of the whole host. Mitigation focus: Upgrade affected Linux kernels to 2.6.38 or a vendor-supported fixed build.; Upgrade affected OpenBSD systems to 4.9 or a vendor-supported fixed build.; Check distribution advisories for backported fixes on maintained legacy releases..
