A vulnerability classified as critical has been found in MediaTek MT2718, MT6739, MT6761, MT6765, MT6768, MT6781, MT6789, MT6833, MT6835, MT6853, MT6855, MT6877, MT6878, MT6879, MT6883, MT6885, MT6886, MT6889, MT6893, MT6895, MT6897, MT6899, MT6983, MT6985, MT6989, MT6991, MT8196, MT8676, MT8678, MT8792 and MT8793. Affected is some unknown processing of the component Display. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

In display, there is a possible out of bounds write due to a missing bounds check. 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: ALPS10196993; Issue ID: MSV-4804.

The advisory is available at corp.mediatek.com. This vulnerability is traded as CVE-2025-20769 since 11/01/2024. The exploitability is told to be easy. Local access is required to approach this attack. The exploitation requires an enhanced level of successful authentication. The technical details are unknown and an exploit is not available.

Applying the patch ALPS10196993 is able to eliminate this problem.
