Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
An issue was discovered on Samsung mobile devices with software through 2016-05-27 (Exynos AP chipsets). A local graphics user can cause a Kernel Crash via the fb0(DECON) frame buffer interface. The Samsung ID is SVE-2016-7011 (October 2016).

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

A local graphics user can trigger a kernel crash via the fb0 (DECON) frame buffer interface on Samsung mobile devices with Exynos AP chipsets running software through May 2016. This is a local denial-of-service vulnerability where the DECON framebuffer driver fails to properly validate or handle certain graphics user operations, leading to a kernel panic.

MitigationApply the October 2016 Samsung security update (SVE-2016-7011) which patches the DECON framebuffer driver vulnerability. Users should update their device firmware to a version containing this security patch.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify device chipset architecture
    Check if the Samsung mobile device uses an Exynos AP chipset (this information is typically available via device specifications, /proc/cpuinfo, or diagnostic utilities)
    Affected if The device does NOT use an Exynos chipset - this vulnerability only affects Exynos-based Samsung devices
  2. Verify the DECON framebuffer interface exists
    Check for the presence of /dev/fb0 or fb0 in /sys/class/graphics/ which indicates the DECON framebuffer driver is loaded and active
    Affected if The fb0 (DECON) framebuffer interface is present and accessible to graphics users
  3. Determine firmware/software version
    Check the Android build date or firmware version on the Samsung Exynos device (available in Settings > About Phone > Build number or via getprop ro.build.date.utc)
    Affected if The firmware was released on or before May 2016 and has not received the October 2016 security update (SVE-2016-7011)
  4. Confirm unpatched kernel driver
    If accessible, check the kernel version and DECON driver version against the patched version included in the October 2016 Samsung security update
    Affected if The kernel driver remains unpatched and the October 2016 Samsung security patch (SVE-2016-7011) has not been applied

A user is affected if they have a Samsung device with an Exynos chipset running firmware from May 2016 or earlier that still contains the vulnerable DECON framebuffer driver and has not received the October 2016 security update.
