Vulnerability AssessmentAI
| Exploitation | Requires attacker to broadcast crafted FILS Discovery Frames with malformed action sizes during WiFi initial scanning. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Despite the CVSS base score of 7.6 High, real-world risk is moderate and context-dependent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker positions themselves within WiFi range of a target device containing a vulnerable Snapdragon chipset, such as in a corporate office, conference center, or public venue. When the victim's device performs periodic network scanning (either automatic background scans or user-initiated WiFi network searches), the attacker broadcasts malicious FILS Discovery frames with crafted action field sizes exceeding parser boundaries. … |
| Remediation | Apply firmware updates provided in the Qualcomm April 2026 Security Bulletin available at https://docs.qualcomm.com/product/publicresources/securitybulletin/april-2026-bulletin.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify Snapdragon WiFi-enabled devices in inventory (mobile devices, IoT endpoints, automotive systems) and document affected firmware versions. …
