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
Possible memory corruption in RPM region due to improper XPU configuration in Snapdragon Connectivity, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Wired Infrastructure and Networking

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

Memory corruption vulnerability in the RPM (Resource Power Manager) region of Qualcomm Snapdragon chips caused by improper XPU (protection unit) configuration. This allows potential arbitrary memory writes in a critical low-level system component, potentially leading to privilege escalation or system compromise.

MitigationApply firmware security patches released by Qualcomm and distributed through OEM device manufacturers. Organizations should identify and update all affected devices through official vendor channels.

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 device Qualcomm Snapdragon chip model
    Check the device specifications, system-on-chip (SoC) information, or boot logs for the specific Qualcomm Snapdragon model number (e.g., via 'cat /proc/cpuinfo' or manufacturer documentation)
    Affected if The device uses a Snapdragon SoC that incorporates one of the listed affected PMIC firmware components (Ar8035, Pm4125, Pm4250, Pm6125, Pm6150a, Pm6150l, Pm6350, or Pm7250b)
  2. Locate the Power Management IC (PMIC) firmware version
    Access the PMIC/RPM firmware information through device diagnostics, bootloader logs (dmesg, boot logs), or manufacturer-provided firmware version utilities; this often requires root access or manufacturer diagnostic tools
    Affected if The PMIC firmware version cannot be determined or shows a firmware version that has not been patched by the OEM after the CVE disclosure date (2020)
  3. Verify OEM firmware update status
    Contact the device manufacturer or check their security advisory pages for the specific device model to confirm whether a firmware patch for CVE-2020-11210 has been applied
    Affected if The device manufacturer has not released or applied a security patch addressing this CVE, or the device is running original factory firmware without updates

A user is affected if their device contains a Qualcomm Snapdragon SoC with any of the listed PMIC firmware components (Ar8035, Pm4125, Pm4250, Pm6125, Pm6150a, Pm6150l, Pm6350, Pm7250b) and the OEM has not released or applied a corresponding security patch for CVE-2020-11210.
