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

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

This vulnerability allows information exposure through debug logging statements that use the %p format specifier, which leaks kernel memory addresses. This can help attackers bypass security mechanisms like ASLR by revealing pointer addresses in memory.

MitigationApply the 2018-04-05 or later security patch level to affected devices, or work with the device OEM/vendor to obtain and deploy firmware updates that remove %p usage from debug logging statements.

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 and firmware version
    Determine the exact model number (Mdm9206, Mdm9607, Fsm9055, Ipq4019, Mdm9635m, Mdm9640, Mdm9650, or Qca4531) and its current firmware version through device administrative interface, CLI, or AT commands
    Affected if Device model matches one of the listed affected Qualcomm products and firmware is present
  2. Check security patch level
    Locate the security patch level or build date in the device firmware information (often visible in system settings, boot logs, or firmware metadata)
    Affected if Security patch level is earlier than 2018-04-05 or cannot be determined
  3. Verify debug logging configuration
    Examine the device logging configuration to determine if debug-level logging is enabled and whether kernel debug messages are being written to accessible logs
    Affected if Debug logging is enabled and kernel messages are being written to accessible log files or serial output
  4. Inspect logging statements for %p usage
    If firmware binary or source code access is available, search for format strings containing %p specifier in logging statements within kernel or driver code
    Affected if Debug logging statements using %p format specifier are present in the firmware

The device is affected if it runs one of the listed Qualcomm firmware models and has a security patch level earlier than 2018-04-05 with debug logging containing %p specifier enabled.

Mitigation

Apply the 2018-04-05 or later security patch level to affected devices, or work with the device OEM/vendor to obtain and deploy firmware updates that remove %p usage from debug logging statements.
