Severity by source
AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Adjacent Wi-Fi range gives AV:A; unauthenticated no-interaction over-the-air parsing bug gives AC:L/PR:N/UI:N; firmware-to-host compromise justifies S:C with full C/I/A impact.

Memory Corruption when processing Device Capability Extended attributes in certain NAN Service Discovery Frames with invalid length values.
AnalysisAI
Memory corruption in Qualcomm Snapdragon Wi-Fi/NAN firmware allows an attacker within wireless range to overflow a stack buffer by sending Neighbor Awareness Networking (NAN) Service Discovery Frames whose Device Capability Extended attributes carry invalid length values (CWE-121). With CVSS:3.1/AV:A/AC:L/PR:N/UI:N and a scope-changed 9.6 score, an unauthenticated adjacent attacker can achieve high-impact compromise potentially crossing from the wireless subsystem into the host. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target Snapdragon device to have Wi-Fi and NAN (Neighbor Awareness Networking / Wi-Fi Aware) enabled and processing Service Discovery Frames, and the attacker must be within Wi-Fi radio range (AV:A adjacent). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are consistent and point to genuine high priority within its exposure model. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker within Wi-Fi range of a victim device broadcasts crafted NAN Service Discovery Frames containing Device Capability Extended attributes with invalid length fields. The victim's Snapdragon firmware parses the malformed attribute, overflows a stack buffer, and the attacker corrupts memory to crash or potentially execute code in the wireless subsystem with possible escalation to the host. … |
| Remediation | Patch available per vendor advisory: apply the fixes referenced in Qualcomm's August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html) as delivered through OEM/carrier firmware and Android security updates; no exact standalone fix version is provided in the input, so track the specific patched firmware level published by your device vendor. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of all Snapdragon Wi-Fi/NAN-enabled devices in your environment and assess the operational impact of disabling NAN Service Discovery on non-critical systems; contact Qualcomm and device manufacturers directly for patch availability timelines. …
