CVE-2024-20083

CVSS 9.8v3.1pub. 2024-08-14upd. 2025-05-30

In venc, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08810810 / ALPS08805789; Issue ID: MSV-1502.

🤖 AI Analysis
How it works

The vulnerability (CWE-787) consists of writing data outside the allocated memory area in the venc component (video encoder). Lack of buffer boundary checks allows exceeding the write range, which can result in overwriting critical data structures in memory. Exploitation requires System execution privileges, but does not require any user interaction.

Impact

An attacker with System execution privileges can achieve local privilege escalation, potentially gaining full control over the device's operating system.

Mitigation & patch

Apply patches available from the manufacturer according to the references. Patch identifiers: ALPS08810810 / ALPS08805789 (Issue ID: MSV-1502), published in the MediaTek security bulletin for August (August 2024).
