CVE-2026-20446 is an out-of-bounds write vulnerability in the secure boot component of MediaTek chipsets, specifically affecting the MT6813 version. The issue arises from an integer overflow that can lead to memory corruption. Exploitation requires local access with user-level privileges but does not require user interaction. The vulnerability can cause a local denial of service by crashing the device. A patch has been identified (Patch ID: ALPS09963054), but the current patch status is not confirmed from the available data.

CVE-2026-20433 is a high-severity vulnerability in MediaTek chipsets involving an out-of-bounds write in the modem component due to a missing bounds check. Exploitation requires a user device to connect to a rogue base station controlled by an attacker, with no additional execution privileges needed. User interaction is necessary for exploitation. The vulnerability affects a wide range of MediaTek chipset models. No official patch or remediation level has been confirmed yet.

CVE-2026-20432 is a high-severity vulnerability in MediaTek chipsets involving an out-of-bounds write in the modem component due to a missing bounds check. Exploitation requires user interaction and a connection to a rogue base station controlled by an attacker. Successful exploitation could lead to remote escalation of privilege with high impact on confidentiality, integrity, and availability. A patch identified as MOLY01406170 exists, but no official remediation level or patch availability confirmation is provided in the data. The vulnerability affects a wide range of MediaTek chipset models.

CVE-2026-20431 is a vulnerability in MediaTek chipsets that can cause a system crash due to a logic error in the modem. This flaw allows a remote denial of service (DoS) attack if a user equipment (UE) connects to a rogue base station controlled by an attacker. Exploitation does not require user interaction or additional privileges. The issue affects multiple MediaTek chipset models. No official patch or remediation level has been confirmed yet.
