Memory corruption while processing a packet with a size close to the maximum allowed value.
AnalysisAI
Memory corruption in Qualcomm Snapdragon platforms occurs when a packet with a size value near the maximum allowable limit is processed, triggering an integer overflow (CWE-190) that leads to a buffer overflow condition. Affected Snapdragon chipsets - used extensively in Android smartphones, IoT, and automotive platforms - are exposed to local exploitation with low privileges, yielding high confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution on the target Snapdragon device with at least low-privilege access (PR:L per CVSS vector) - a standard installed application context satisfies this on Android. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) scores 7.8 High. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A malicious application running with standard user-level privileges on an affected Snapdragon-based Android device crafts a packet or IPC message with a size field set near the integer maximum and submits it to a vulnerable kernel driver or firmware interface. The driver's size arithmetic overflows, resulting in an undersized buffer allocation, and the subsequent memory write corrupts adjacent heap or stack memory. … |
| Remediation | The primary fix is to apply the patches detailed in Qualcomm's August 2026 Security Bulletin 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 Qualcomm Snapdragon devices across your organization (smartphones, IoT devices, automotive systems), and restrict local access by disabling unnecessary user accounts and administrative interfaces where operationally feasible. …
