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
In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Mobile SD 400 and SD 800, when writing the Full Disk Encryption key to crypto engine, information leak could occur.

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

On Qualcomm Snapdragon SD 400 and SD 800 processors, an information leak vulnerability exists in the Full Disk Encryption (FDE) key handling path. When the FDE key is written to the crypto engine, improper handling allows key material to potentially be exposed or leaked before it is properly protected in secure hardware. This affects Android systems before the 2018-04-05 security patch level.

MitigationApply the Android security patch level from April 5, 2018 or later, which contains the fix for this FDE key information leak in the Qualcomm crypto subsystem. Organizations should inventory affected devices and ensure they receive OEM firmware updates.

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 Qualcomm processor model
    Check the device specifications or use a system info app to determine if the device uses a Snapdragon SD 400 or SD 800 processor. On Android, this can often be found under Settings > About Phone > Hardware info, or by checking /proc/cpuinfo for chip identification.
    Affected if The device is confirmed to use a Qualcomm Snapdragon SD 400 or SD 800 processor.
  2. Check if Full Disk Encryption is enabled
    On Android, verify FDE status by checking the device encryption settings under Settings > Security > Encryption, or by running 'getprop ro.crypto.state' and 'getprop vold.decrypt' in ADB shell. FDE shows as 'encrypted' when enabled.
    Affected if Full Disk Encryption is enabled and the device uses the affected Qualcomm processors.
  3. Verify the Android security patch level date
    Check the Android security patch level by going to Settings > About Phone > Security patch level, or by running 'getprop ro.build.version.security_patch' in ADB shell. This displays the date in YYYY-MM-DD format.
    Affected if The security patch level is earlier than 2018-04-05, meaning the device has not received the fix for this vulnerability.

A device is affected if it uses a Qualcomm Snapdragon SD 400 or SD 800 processor, has Full Disk Encryption enabled, and has a security patch level earlier than April 5, 2018.
