AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Description explicitly states user interaction is needed (UI:R, overriding vendor UI:N); 'system crash' outcome supports A:H rather than vendor A:N.

In gpu, there is a possible system crash due to use after free. This could lead to local information disclosure with User execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS11122991; Issue ID: MSV-8132.
AnalysisAI
Use-after-free in the MediaTek GPU kernel driver on chipsets MT6991 and MT8799 allows a local attacker with standard user privileges to read freed kernel or GPU memory, potentially exposing sensitive data such as pointers, credentials, or cryptographic material. The same condition may cause a full system crash, consistent with the Denial of Service tag and the 'system crash' language in the description. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local code execution on the target device with at minimum standard Android user-level privileges (PR:L per vendor CVSS). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor-assigned CVSS 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) correctly constrains the attack surface to local access with user-level privileges, significantly limiting the population of viable attackers. … 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 vendor-released patch ALPS11122991 (Issue MSV-8132), distributed through OEM/carrier firmware updates that incorporate the MediaTek September 2026 Security Bulletin (https://www.mediatek.com/product-security-bulletin/September-2026). … Detailed patch versions, workarounds, and compensating controls in full report. |
