Memory Corruption when accessing an output buffer without validating its size during IOCTL processing.
AnalysisAI
Local privilege escalation in Qualcomm Snapdragon products allows authenticated attackers to gain kernel-level code execution through memory corruption during IOCTL processing. The vulnerability stems from unchecked buffer size validation when writing to output buffers, enabling high-impact compromise of confidentiality, integrity, and availability on affected mobile and embedded devices. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Attacker must have low-privilege local user access to the target system. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability presents moderate-to-high real-world risk with nuanced prioritization factors. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has gained local access to a Snapdragon-based Android device through a malicious application downloaded by the user could exploit this vulnerability to escalate privileges from the application sandbox to kernel level. The attacker's app would craft a malicious IOCTL request targeting the vulnerable Snapdragon driver, passing parameters that cause the driver to write beyond allocated output buffer boundaries without proper size validation. … |
| Remediation | Primary remediation requires applying vendor-supplied firmware updates from Qualcomm's April 2026 security bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/april-2026-bulletin.html) once published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all mobile devices, IoT hardware, and embedded systems using Qualcomm Snapdragon chipsets in your environment and identify affected product models. …
