Detailsinfo

A vulnerability was found in MediaTek MT2735, MT6767, MT6768, MT6769, MT6769K, MT6769S, MT6769T, MT6769Z, MT6779, MT6781, MT6783, MT6785, MT6785T, MT6785U, MT6789, MT6833P, MT6853, MT6853T, MT6855, MT6855T, MT6873, MT6875, MT6875T, MT6877, MT6877T, MT6877TT, MT6880, MT6880T, MT6880U, MT6883, MT6885, MT6889, MT6890, MT6891, MT6893, MT8666, MT8673, MT8675, MT8765, MT8766, MT8768, MT8771, MT8781, MT8786, MT8788, MT8788E, MT8789, MT8791T, MT8795T, MT8797 and MT8798 and classified as critical. This issue affects an unknown part of the component Modem. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to 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). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In Modem, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY00720348; Issue ID: MSV-2392.

The advisory is shared at corp.mediatek.com. The identification of this vulnerability is CVE-2024-20154 since 11/02/2023. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

Applying the patch MOLY00720348 is able to eliminate this problem.
