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 for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, while processing a specially crafted QCA_NL80211_VENDOR_SUBCMD_NDP cfg80211 vendor command a buffer over-read can 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

A buffer over-read vulnerability exists in the cfg80211 vendor command handler for QCA_NL80211_VENDOR_SUBCMD_NDP in the Linux kernel's Qualcomm WiFi driver. When processing specially crafted cfg80211 vendor commands, the code reads beyond the allocated buffer boundary, potentially exposing sensitive kernel memory contents to an attacker.

MitigationApply the vendor-specific kernel security patch or update to an Android security patch level that includes the fix. For enterprise fleets, identify affected devices and coordinate with device manufacturers/carriers for kernel 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. Verify Android version
    Go to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB
    Affected if The version is exactly 8.0 (Oreo)
  2. Confirm Qualcomm WiFi driver in use
    Check kernel config for CONFIG_CFG80211 and CONFIG_QCA_NL80211_VENDOR, or check 'ls /sys/kernel/debug/wlan_qcom/' via ADB if available
    Affected if The device uses Qualcomm's cfg80211 vendor implementation
  3. Check for NDP vendor subcommand support
    Inspect kernel config for CONFIG_NL80211_TESTMODE or grep kernel source for QCA_NL80211_VENDOR_SUBCMD_NDP definition
    Affected if The NDP subcommand handler is compiled into the kernel
  4. Review kernel logs for triggers
    Check dmesg or logcat for unusual cfg80211 vendor command activity, or inspect /proc/net/nl80211 for debug entries
    Affected if NDP vendor commands are being processed by the kernel

A device is affected if it is running Android 8.0 with a Qualcomm WiFi driver that includes the vulnerable cfg80211 vendor command handler for NDP.
