In MiracastService, there is a possible escalation of privilege due to a confused deputy. This could lead to local denial of service with User execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS11060069 / DTV04881615; Issue ID: MSV-7882.
AnalysisAI
MiracastService on MediaTek Smart TV and DTV chipsets exposes a confused deputy condition (CWE-926) that allows a local app running with user-level privileges to trigger a denial-of-service against the Wi-Fi Display subsystem. The flaw stems from an improperly exported Android application component that lets an unprivileged caller invoke MiracastService capabilities without holding the necessary permissions, crashing or disabling the service. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local attacker with user-level execution privileges (PR:L) already running code on a device built on one of the 29 affected MediaTek chipsets. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.5 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) accurately frames this as a local denial-of-service requiring low user privileges - not a network-exploitable flaw. … 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 MediaTek patch identified by Patch ID ALPS11060069 / DTV04881615, which addresses MSV-7882 and is documented in the MediaTek September 2026 Security Bulletin at https://www.mediatek.com/product-security-bulletin/September-2026. … Detailed patch versions, workarounds, and compensating controls in full report. |
