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
Driver may access an invalid address while processing IO control due to lack of check of address validation in Snapdragon Connectivity in QCA6390

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 confidence

A driver in Snapdragon Connectivity (QCA6390) fails to validate addresses properly when processing IO control requests, allowing the driver to access invalid memory addresses due to missing address validation checks.

MitigationApply the vendor-provided firmware/driver patch from Qualcomm for the Snapdragon Connectivity component. No user-configurable workarounds are available for driver-level address validation flaws.

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 QCA6390 hardware presence
    Run 'lspci | grep -i qualcomm' or check system logs/dmesg for QCA6390 or Snapdragon Connectivity device entries
    Affected if The system contains a QCA6390 wireless adapter or Snapdragon Connectivity component
  2. Check wireless driver module
    Run 'lsmod | grep -i ath' or 'iw list' to identify the wireless driver in use and its associated firmware
    Affected if The driver loaded is associated with QCA6390 firmware and exposes IOCTL interfaces
  3. Verify IOCTL interface accessibility
    Check /dev or /sys for network device nodes (e.g., wlan0) and inspect driver ioctl handler availability via 'ethtool -i <interface>' or similar driver info tools
    Affected if A wireless interface exists and the driver exposes IOCTL handlers for request processing
  4. Confirm firmware version if exposed
    Check /lib/firmware or use 'cat /sys/class/net/*/device/firmware_version' if available, or review boot logs for 'QCA6390' firmware loading messages
    Affected if The firmware version string indicates QCA6390 or Snapdragon Connectivity firmware is loaded (all versions are affected)

A system is affected if it contains QCA6390 hardware with the vulnerable driver that processes IO control requests without proper address validation.
