CVE-2019-14047
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 · uneditedWhile IPA driver processes route add rule IOCTL, there is no input validation of the rule ID prior to adding the rule to the IPA HW commit list in Snapdragon Auto, Snapdragon Compute, Snapdragon Connectivity, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voice & Music, Snapdragon Wearables in APQ8053, APQ8096AU, MDM9607, MSM8909W, MSM8996, MSM8996AU, QCN7605, QCS605, SC8180X, SDA845, SDX20, SDX24, SDX55, SM8150, SXR1130
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 confidenceA missing input validation vulnerability exists in the Qualcomm IPA (Internet Protocol Accelerator) driver where the rule ID is not validated before being added to the IPA hardware commit list during route add rule IOCTL processing. This could allow an attacker to trigger memory corruption by providing an invalid or malicious rule ID, potentially leading to denial of service or code execution in the kernel context.

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.
-
Identify the Qualcomm SoC model in the deviceCheck the system-on-chip or baseband processor by reviewing /proc/cpuinfo, kernel boot logs, or device hardware specifications. Look for identifiers such as Apq8053, Apq8096au, Mdm9607, Msm8909w, Msm8996, Msm8996au, Qcn7605, or Qcs605.Affected if The device uses any of the listed Qualcomm chip models (Apq8053, Apq8096au, Mdm9607, Msm8909w, Msm8996, Msm8996au, Qcn7605, Qcs605)
-
Determine the firmware version of the Qualcomm componentCheck the baseband or radio firmware version via AT commands (for modems), through /proc/version, /sys/firmware, or OEM-specific diagnostic interfaces. Compare the firmware version against the affected product list.Affected if The firmware version corresponds to any of the listed products (all versions are affected)
-
Verify if the IPA driver is loadedCheck for the presence of the IPA driver module in the kernel. Look for 'ipa' in /proc/modules, or check for 'ipa' in lsmod output, or inspect /sys/kernel/debug/ipa/ if debugfs is available.Affected if The IPA (Internet Protocol Accelerator) driver is present and loaded in the kernel
-
Check for access to the IPA route add rule IOCTL interfaceInspect /dev/ipa or similar device nodes used for IPA driver communication. Look for IOCTL calls related to route add rule functionality by examining driver source code or using tools like strace on processes that interact with IPA.Affected if The IOCTL interface for route add rule (IPA_IOC_ADD_RULE) is exposed and accessible to user space or untrusted components
The device is affected if it uses any of the listed Qualcomm SoC models with IPA driver support, since all firmware versions for these products contain the unvalidated rule ID vulnerability in the IPA driver's IOCTL handler.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware/driver updates that implement proper input validation for rule IDs in the IPA driver's IOCTL handler. This is a kernel-level fix requiring updates from Qualcomm or device OEMs.
