Security readout for executives and security teams
Plain-English summary
CVE-2017-11090 is a Qualcomm Android kernel-related issue where malformed Wi-Fi security data from an app can cause the driver to read beyond the expected buffer. The public bundle does not provide severity, CVSS, confirmed impact, or active exploitation evidence.
Executive priority
Treat this as a legacy mobile firmware exposure requiring inventory-driven remediation. Urgency is higher for managed fleets with old Qualcomm-based Android devices, but the public evidence does not support a critical or actively exploited rating.
Technical view
The issue is a buffer overread in __wlan_hdd_cfg80211_set_pmksa when user space supplies a PMKID shorter than WLAN_PMKID_LEN. Affected entries are Qualcomm Android for MSM, Firefox OS for MSM, QRD Android, and CAF Android releases using the Linux kernel.
Likely exposure
Exposure is most likely on devices or firmware built from affected Qualcomm CAF Android/Linux kernel releases. Standard Android devices without that Qualcomm CAF WLAN driver path are not confirmed affected by the provided sources.
Exploitation context
The source describes a local user-space input path into WLAN PMKSA handling. KEV is false, and the bundle cites no active exploitation, public exploit, remote attack path, or weaponized details.
Researcher notes
Public data is sparse: no CVSS, CWE, patch diff, or exploit status is included. The function name points to Qualcomm WLAN cfg80211 PMKSA handling; validate against exact vendor kernel trees before declaring exposure.
Mitigation direction
- Check OEM, Qualcomm, and Android bulletin guidance for CVE-2017-11090.
- Apply firmware or Android security updates that include this CVE where available.
- Prioritize devices using Qualcomm CAF kernels or Android for MSM builds.
- Restrict untrusted app installation on potentially affected legacy devices.
- Retire unsupported devices that cannot receive relevant vendor fixes.
Validation and detection
- Inventory devices by OEM, chipset, Android patch level, and kernel lineage.
- Identify firmware based on Qualcomm CAF Android/Linux kernel releases.
- Check vendor advisories for explicit CVE-2017-11090 inclusion.
- Review WLAN driver source for __wlan_hdd_cfg80211_set_pmksa handling.
- Confirm remediation through vendor patch level or fixed source revision.
