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 1280, 2200, 1380, 1480, 2400, 1580, and 2500. A NULL pointer dereference of session->ncp_hdr_buf in __pilot_parsing_ncp() causes 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 · moderate confidence

A NULL pointer dereference vulnerability exists in the __pilot_parsing_ncp() function of Samsung's Exynos mobile processors (1280, 2200, 1380, 1480, 2400, 1580, and 2500). The vulnerability occurs when session->ncp_hdr_buf is dereferenced without proper validation, causing a denial of service condition.

MitigationApply vendor-supplied firmware/security updates from Samsung for affected Exynos processors. Users should ensure their devices receive the latest security patches through standard OTA update mechanisms.

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 processor model in your device
    Check your device specifications or system information to determine if the device uses a Samsung Exynos processor. Common methods include checking the device info in Settings > About Phone, or using terminal commands like 'cat /proc/cpuinfo' on Android.
    Affected if The device contains an Exynos 1280, 1380, 1480, 1580, 2200, 2400, or 2500 processor.
  2. Confirm the specific Exynos variant
    Review the full device model number and confirm the exact Exynos variant. Some devices may have different regional variants using different processors.
    Affected if The device uses any of the affected Exynos variants: 1280, 1380, 1480, 1580, 2200, 2400, or 2500.
  3. Check the baseband or modem firmware version
    On Android devices, access Settings > About Phone > Baseband version or use terminal commands like 'getprop gsm.version.baseband' to view the modem firmware version.
    Affected if The baseband/modem firmware is running on an affected Exynos processor (all versions of these processors are affected per the CVE).

A user is affected if their mobile device contains any of the listed Exynos processors (1280, 1380, 1480, 1580, 2200, 2400, or 2500) regardless of firmware version, as all versions contain the vulnerable __pilot_parsing_ncp() function with the unvalidated session->ncp_hdr_buf dereference.
