CVE-2020-11242
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 · uneditedUser could gain access to secure memory due to incorrect argument into address range validation api used in SDI to capture requested contents in Snapdragon Industrial IOT, Snapdragon Mobile
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 confidenceA vulnerability in the SDI (Secure Display Interface) component of Qualcomm Snapdragon Industrial IOT and Snapdragon Mobile processors allows unauthorized access to secure memory. The issue stems from an incorrect argument being passed to the address range validation API, which fails to properly restrict memory access boundaries and enables a local user to read sensitive secure memory contents.

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 checksWork through these to decide whether this CVE applies to you.
-
Inventory Qualcomm Snapdragon IoT and Mobile devicesScan your environment for devices using Qualcomm Snapdragon Industrial IOT or Snapdragon Mobile processors. Identify the specific chip model(s) in use by reviewing device hardware specifications, OEM documentation, or querying device management systems.Affected if Any device uses one of the affected chip models: Pm660, Pm660a, Pm660l, Pm855a, Pmm855au, Qat3514, Qat3522, or Qat3550
-
Identify firmware version of affected Qualcomm componentsQuery the device firmware or use OEM-provided diagnostic tools to retrieve the firmware version for the specific Qualcomm component (Pm660, Pm660a, Pm660l, Pm855a, Pmm855au, Qat3514, Qat3522, or Qat3550). Consult OEM documentation for the appropriate command or interface.Affected if The firmware version matches any of the affected product lines listed (all versions of Pm660, Pm660a, Pm660l, Pm855a, Pmm855au, Qat3514, Qat3522, Qat3550 are affected)
-
Confirm SDI component is present and enabledVerify that the SDI (Secure Display Interface) component is present on the device and enabled in the firmware configuration. Use OEM diagnostic interfaces or check firmware configuration files for SDI module status.Affected if SDI (Secure Display Interface) component is present and active on the device
A device is affected if it uses any of the affected Qualcomm chip models (Pm660, Pm660a, Pm660l, Pm855a, Pmm855au, Qat3514, Qat3522, Qat3550) and has the SDI component enabled, as all firmware versions of these chips contain the vulnerability.
