AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
Adjacent unauthenticated attacker sends a malformed Wi-Fi frame requiring no interaction; scope change reflects crash propagation from Wi-Fi driver to host OS; no confidentiality or integrity impact.

Transient DOS when processing a short target wake time channel usage response frame with insufficient packet size.
AnalysisAI
Transient denial of service in Qualcomm Snapdragon's Wi-Fi 6 stack allows adjacent, unauthenticated attackers to crash affected devices by transmitting a malformed Target Wake Time (TWT) channel usage response frame with an undersized packet payload. The CVSS scope change (S:C) indicates the crash propagates beyond the Wi-Fi subsystem to impact the broader host environment. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The target device must be equipped with a Qualcomm Snapdragon chipset that implements Wi-Fi 6 (802.11ax) TWT frame processing, and the Wi-Fi interface must be active and capable of receiving TWT management frames. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.4 (High) score reflects adjacent network attack vector (AV:A), low complexity (AC:L), no required privileges (PR:N), no user interaction (UI:N), and a scope change (S:C) with high availability impact (A:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker within Wi-Fi radio range of a Snapdragon-equipped device - such as a smartphone, tablet, or Wi-Fi 6 IoT sensor - crafts a TWT channel usage response frame with a payload shorter than the minimum size the Snapdragon parser expects. Transmitting this frame causes the Wi-Fi stack to perform a buffer over-read, triggering a transient system crash or reset. … |
| Remediation | Apply firmware and driver updates published by Qualcomm in the August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html); specific patched firmware or driver version numbers were not present in the available data and must be obtained directly from the bulletin or via OEM-distributed security updates. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit your device inventory to identify all Snapdragon-based smartphones, tablets, and IoT devices and categorize by business criticality and network exposure. …
