Severity by source
AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Local-only UAF requiring System privilege (PR:H, AV:L); no scope change despite TEE boundary; full CIA impact from memory corruption escalation.
Primary rating from Vendor (MediaTek).
CVSS VectorVendor: MediaTek
Lifecycle Timeline
2DescriptionCVE.org
In geniezone, there is a possible escalation of privilege due to use after free. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10900510; Issue ID: MSV-6781.
AnalysisAI
Local privilege escalation in MediaTek's geniezone Trusted Execution Environment component affects 17 Android chipsets through a use-after-free memory corruption flaw. Exploitation requires an attacker who has already obtained System-level privilege on the device, allowing them to escalate further - potentially to kernel or TEE privilege - with full confidentiality, integrity, and availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker already holds System-level privilege on the affected Android device - this is a post-compromise escalation step, not an initial access vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.7 score (AV:L/AC:L/PR:H/UI:N/S:U) reflects the substantial prerequisite of System-level privilege, which materially limits the attacker pool. … 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 | Apply the patch distributed through the MediaTek September 2026 Product Security Bulletin (Patch ID: ALPS10900510, Issue ID: MSV-6781), available at https://www.mediatek.com/product-security-bulletin/September-2026. … Detailed patch versions, workarounds, and compensating controls in full report. |
