In Android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, while processing the QCA_NL80211_VENDOR_SUBCMD_SET_TXPOWER_SCALE_DECR_DB vendor command, in which attribute QCA_WLAN_VENDOR_ATTR_TXPOWER_SCALE_DECR_DB contains fewer than 1 byte, a buffer overrun occurs.

Security readout for executives and security teams

Plain-English summary

This CVE describes a buffer overrun in Qualcomm-related Android kernel code when a malformed Wi-Fi vendor command contains an attribute shorter than expected. The sources do not provide severity, CVSS, exploit status, or clear impact details, so business urgency depends on whether your device fleet uses affected Qualcomm CAF-derived Android builds.

Executive priority

Treat this as an inventory and lifecycle-management issue unless vendor data shows affected devices remain in use. It is not KEV-listed and lacks severity data, but kernel-adjacent buffer overruns in mobile fleets warrant closure through supported firmware updates.

Technical view

The issue occurs while processing QCA_NL80211_VENDOR_SUBCMD_SET_TXPOWER_SCALE_DECR_DB when QCA_WLAN_VENDOR_ATTR_TXPOWER_SCALE_DECR_DB has fewer than 1 byte. Affected products are listed as Android for MSM, Firefox OS for MSM, and QRD Android, including Android CAF Linux kernel releases. Attack vector, privileges, and impact are not specified in the provided sources.

Likely exposure

Likely exposure is limited to Qualcomm MSM/CAF-derived Android or Firefox OS builds, especially OEM firmware using affected Qualcomm Wi-Fi kernel/vendor code. Standard non-Qualcomm Android builds are not established as affected by the provided sources.

Exploitation context

The source bundle does not report active exploitation, and CISA KEV status is false. No cited source provides exploit availability, required attacker position, or practical exploitation conditions.

Researcher notes

Evidence is sparse. The record identifies a short attribute length handling flaw in a Qualcomm nl80211 vendor command path, but omits CVSS, CWE, affected chipsets, commit references, and exploitation preconditions. Avoid assuming remote exploitability or universal Android exposure.

Mitigation direction

  • Inventory Qualcomm MSM and CAF-derived Android devices in managed fleets.
  • Check OEM, Qualcomm, and Android bulletins for CVE-2017-14899 coverage.
  • Apply applicable vendor firmware or Android security updates where available.
  • Retire or isolate unsupported affected devices without vendor fixes.
  • Prioritize devices exposed to untrusted local apps or unmanaged users.

Validation and detection

  • Map device models to Qualcomm MSM, QRD, or CAF-derived firmware lineage.
  • Confirm Android security patch level and OEM advisory coverage for this CVE.
  • Review vendor release notes for wlan or kernel fixes tied to CVE-2017-14899.
  • Flag devices that no longer receive OEM security updates.
  • Document uncertainty where firmware lineage cannot be confirmed.
