Severity by source
AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
Requires System-level Android privilege (PR:H) and local device access; only Audio HAL data confidentiality is impacted, with no integrity or availability effect.
Primary rating from Vendor (MediaTek).
CVSS VectorVendor: MediaTek
Lifecycle Timeline
3DescriptionCVE.org
In Audio HAL, there is a possible information disclosure due to a missing permission check. This could lead to local information disclosure if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11087632; Issue ID: MSV-8244.
AnalysisAI
Local information disclosure in MediaTek's Audio Hardware Abstraction Layer affects 63 distinct chipsets, from MT6761 to MT8910, allowing a process already operating at Android System privilege to bypass an absent permission check and extract audio HAL data without authorization. Patch ID ALPS11087632 (Issue MSV-8244) addresses the missing authorization gate, and MediaTek published remediation through the September 2026 security bulletin. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has already obtained Android System-level privilege on the target device (CVSS PR:H confirmed); this is a significant prerequisite that limits the realistic attacker population to those who have already achieved a meaningful level of device compromise. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.4 score accurately reflects a constrained vulnerability: local attack vector, high privilege prerequisite (Android System), confidentiality-only impact, and no user interaction requirement once System privilege is held. … 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 vendor patch ALPS11087632 distributed through 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. |
