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 Samsung Mobile Processor Exynos 980, 990, 1080, 2100, 1280, 2200, 1380, 1480 and 2400. A Double Free in the mobile processor leads to privilege escalation.

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 double-free memory corruption vulnerability in Samsung Exynos mobile processors (models 980, 990, 1080, 2100, 1280, 2200, 1380, 1480, and 2400) allows an attacker to corrupt memory allocation metadata and achieve privilege escalation to elevated/system privileges.

MitigationApply Samsung firmware/security updates for affected devices; coordinate with Samsung for patch deployment across device ecosystem.

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 model
    Run 'getprop ro.product.model' or check Settings > About Phone > Model Name
    Affected if Device is a Samsung mobile device
  2. Identify chipset/processor model
    Run 'getprop ro.hardware' or check /proc/cpuinfo, or use 'lshw' if available, or check Settings > About Phone > Chipset
    Affected if Chipset matches Exynos 980, 990, 1080, 2100, 1280, 2200, 1380, 1480, or 2400
  3. Check firmware version
    Run 'getprop ro.build.version.security_patch' or check Settings > About Phone > Android security patch level
    Affected if Any version is installed (all versions are affected)
  4. Verify vulnerability trigger condition
    Confirm the device uses the affected Exynos firmware for baseband/modem processing. Check 'getprop ro.baseband' for radio firmware version if accessible.
    Affected if Baseband firmware is from Samsung Exynos (not Qualcomm or other)

If the device uses any of the listed Exynos chipsets (980, 990, 1080, 2100, 1280, 2200, 1380, 1480, 2400), the device is affected regardless of firmware version.
