Cryptographic Issue while processing registration requests with malformed or missing authentication parameters.
AnalysisAI
Authentication bypass in Qualcomm Snapdragon SoCs allows adjacent network attackers to exploit a cryptographic flaw during registration request processing, yielding high confidentiality and integrity compromise without requiring any privileges or user interaction. The flaw, rooted in CWE-306 (Missing Authentication for Critical Function), occurs when registration requests carry malformed or absent authentication parameters, causing the cryptographic subsystem to proceed without validating caller identity. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be on the same adjacent network segment as the target device - for example, the same Wi-Fi access point, Bluetooth range, or local wireless cell. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.1 vector (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) reflects a high-severity flaw with a meaningful but bounded threat surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker positioned on the same wireless network segment as a target Snapdragon-based device crafts a registration request with malformed or deliberately absent authentication parameters and transmits it to the vulnerable cryptographic processing component. The missing authentication check (CWE-306) causes the handler to bypass identity verification and proceed with the registration, granting the attacker unauthorized access to confidential data or the ability to manipulate protected state with high integrity impact. … |
| Remediation | The primary remediation is to apply the firmware update issued by Qualcomm in the August 2026 Security Bulletin, available at https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify and inventory all devices using Qualcomm Snapdragon SoCs and alert security, device management, and executive teams to the unpatched exposure. …
