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.

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 · moderate confidence

A missing bounds check in Android SoC allows an out of bounds write, leading to memory corruption. This is a critical memory safety vulnerability in low-level firmware or drivers running on the System-on-Chip, potentially allowing arbitrary code execution or denial of service.

MitigationApply Android security patches from the SoC vendor (chipset manufacturer) as they become available; this is a firmware-level fix that requires updating the SoC firmware or receiving patched Android security bulletins.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

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 SoC chipset model
    Check device specifications or run 'getprop ro.hardware' or 'cat /proc/cpuinfo' to identify the SoC vendor and model (e.g., Qualcomm, MediaTek, Samsung Exynos, HiSilicon)
    Affected if The device uses a SoC model that received this vulnerability fix from its manufacturer
  2. Check Android security patch level
    Go to Settings > About Phone > Build Number or run 'getprop ro.build.version.security_patch' to see the installed security patch date
    Affected if The security patch level is earlier than the month the CVE fix was released for the specific SoC vendor
  3. Verify if the vulnerable driver component is present
    Check for the presence of the affected low-level media or graphics driver module by examining /system/lib/hw/ or /vendor/lib/hw/ directories for SoC-specific driver libraries
    Affected if Vulnerable SoC-specific driver binaries are present and have not been patched by the vendor
  4. Check vendor firmware version if accessible
    For rooted devices, examine the bootloader or baseband version via 'getprop' commands (e.g., ro.bootloader, ro.baseband) or check /vendor/firmware/ for the base firmware version
    Affected if The firmware version predates the vendor's patched release for this CVE
  5. Confirm SoC vendor security advisory status
    Look up whether the device manufacturer's security advisory or the SoC vendor has published a fix for CVE-2020-0283 affecting this specific chipset
    Affected if No vendor acknowledgment or patch is available for the identified SoC model

A device is affected if it uses a vulnerable SoC chipset model and has not received the vendor-specific firmware or security patch that addresses the missing bounds check in the low-level SoC driver.
