Memory Corruption when processing registry values with incorrect types using a direct query method.
AnalysisAI
Memory corruption in Qualcomm Snapdragon's registry value processing exposes devices to potential code execution by high-privileged local attackers. The flaw, rooted in CWE-120 (classic buffer overflow), is triggered when a direct query method processes registry values supplied with incorrect types - bypassing proper type-length validation and corrupting adjacent memory. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the affected Snapdragon device with high-privilege credentials or a process running at high privilege level (PR:H per CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.7 (Medium) is appropriately calibrated for this vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local attacker who has already obtained high-privilege access on a Snapdragon-based device - for example via a separate privilege escalation vulnerability, a rooted device, or an authorized but malicious system-level process - invokes a registry direct query method and supplies a registry value whose type is intentionally mismatched. The method copies the value without validating the type-length correspondence, overflowing the destination buffer and corrupting adjacent memory. … |
| Remediation | Apply the patches detailed in the Qualcomm August 2026 Security Bulletin (https://docs.qualcomm.com/product/publicresources/securitybulletin/august-2026-bulletin.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
