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 in the Camera in Samsung Mobile Processor and Wearable Processor Exynos 1330, 1380, 1480, 2400, 1580, 2500. An invalid kernel address dereference in the issimian device driver leads to a denial of service.

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 kernel address dereference vulnerability exists in the issimian camera device driver for Samsung Exynos processors (models 1330, 1380, 1480, 2400, 1580, 2500). The flaw allows an attacker to dereference an invalid kernel memory address, potentially causing a kernel panic or denial of service condition.

MitigationApply Samsung's security firmware updates for affected Exynos processors once released. This is a vendor-supplied patch requiring firmware-level remediation; no workarounds are available for kernel-space driver flaws.

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 the Exynos processor model
    Check the device specifications or system information to determine the exact Exynos chip model (e.g., Exynos 1330, 1380, 1480, 1580, 2400, or 2500). On Android devices, this may be visible in Settings > About Phone > SoC details, or via 'cat /proc/cpuinfo' on rooted devices.
    Affected if The processor model is one of: Exynos 1330, 1380, 1480, 1580, 2400, or 2500.
  2. Locate the issimian camera driver
    Check if the issimian camera driver module or driver file exists on the system. On Linux-based firmware images, examine /dev/ or /sys/ for camera-related entries, or search for 'issimian' in the kernel modules directory (e.g., /lib/modules/).
    Affected if The issimian camera driver is present or loaded on the system.
  3. Verify camera driver is active
    Check whether the camera subsystem is initialized and the issimian driver is actively loaded or bound to camera hardware. This may be observable through kernel logs, camera service status, or /sys/class/video4linux/ entries if the driver exposes video devices.
    Affected if The issimian camera driver is actively loaded or bound to camera hardware.
  4. Confirm firmware version
    Retrieve the current firmware version for the Exynos processor. This is typically available through the device bootloader, modem firmware string, or system firmware information (e.g., 'getprop' on Android, or checking /vendor/firmware/).
    Affected if Any firmware version is installed on an affected Exynos model (all versions are vulnerable).

The environment is affected if the device uses any of the listed Exynos processor models (1330, 1380, 1480, 1580, 2400, 2500) and has the issimian camera driver enabled, as all firmware versions for these models contain the vulnerability.
