Vulnerability AssessmentAI
| Exploitation | Attacker requires low-privilege local user access to the target system. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is elevated but constrained by prerequisite access requirements. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has gained low-privilege local access to an Android device through a malicious application (installed via social engineering or compromised app store) leverages this vulnerability by crafting malicious IOCTL calls to the Snapdragon driver. By passing specially crafted parameters that trigger buffer over-read conditions during output buffer processing, the attacker corrupts adjacent kernel memory structures to achieve arbitrary kernel code execution. … |
| Remediation | Apply security updates provided in Qualcomm's 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 and inventory all Snapdragon-based devices in your environment (mobile devices, IoT platforms, automotive systems). …
