Severity by source
AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Local kernel driver reachable from unprivileged app sandbox (AV:L, PR:N); low-complexity heap overflow yields full kernel control (C/I/A:H); scope unchanged as compromise stays within the affected device boundary.
Primary rating from Vendor (MediaTek).

3DescriptionCVE.org
In vdec, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS11262030; Issue ID: MSV-9197.
AnalysisAI
Heap buffer overflow in the vdec (video decoder) kernel driver across 53+ MediaTek SoCs allows a local unprivileged attacker to escalate privileges to kernel level with full system compromise. The CVSS vector (AV:L/AC:L/PR:N/UI:N) reflects that any Android app running on an affected device can trigger this flaw without special permissions or user interaction, consistent with typical Android kernel driver exposure. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution on the device - specifically, a malicious or compromised Android application running on a device with an affected MediaTek chipset. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.4 vector (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) accurately reflects the local, low-complexity, zero-privilege nature of this Android kernel driver attack. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | OEMs shipping devices with affected MediaTek chipsets should integrate the upstream fix under Patch ID ALPS11262030 (Issue MSV-9197) from the MediaTek September 2026 Product Security Bulletin (https://www.mediatek.com/product-security-bulletin/September-2026) and issue device security updates promptly. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all devices using affected MediaTek SoCs in your inventory by cross-referencing device models against the CVE's 53+ SoC list and prioritize by data sensitivity. …
