A new security bulletin has been released by MediaTek for February 2025, which reveals several critical vulnerabilities, which may affect its chipsets used in smartphones, tablets, as well as numerous other devices. There are security issues identified in the bulletin that may allow remote code execution, privilege escalation, and denial of service attacks to be performed on the system.

Among the most significant vulnerability issues (CVE-2025-20633, CVE-2025-20632, CVE-2025-20631) that have been identified in the driver for WLAN access points are three. If this component doesn't perform proper bounds check, a remote attacker could exploit this vulnerability to execute arbitrary code without the need for elevated privileges or the need to interact with the user. 

There is a vulnerability on some chipsets, including the MT7603, MT7615, MT7622, and MT7915, that are running SDK version 7.4.0.1 or earlier. Several MediaTek chipsets contain WLAN Access Points (APs) with a variety of security vulnerabilities, including those designated with the CVE identifier CVE-2025-20631, CVE-2025-20632, and CVE-2025-20633. 

These vulnerabilities are enabled by multiple defects in the WLAN Access Points (APs) drivers. This vulnerability is categorized as an out-of-bounds write vulnerability, which is referred to in CWE-787. It results from flawed bounds checking in the WLAN drivers, which is caused by certain exploits. As a result, MediaTek has been working closely with OEMs for a minimum of two months before the release of the bulletin to ensure that both the necessary security patches are available for these vulnerabilities before the release of the bulletin. 

There is a strong recommendation for users to verify and apply the software updates provided by the device manufacturers as soon as possible so that potential security threats can be mitigated. It is possible to access a complete overview of the MediaTek Product Security Bulletin, including a detailed list of chipsets and software versions that are affected, on the official MediaTek website, which can be accessed by clicking here. Several vulnerabilities pose a significant security threat to a variety of different devices and systems, especially IoT devices, routers, and smartphones built on MediaTek chipsets. 

Threat actors could exploit these flaws to compromise affected systems, potentially resulting in unauthorized access to important data, data breaches, or service disruptions. Independent security research reports alerted MediaTek to the security weaknesses of the impacted SDKs during July. Together with the independent researchers, MediaTek has developed patched versions of these SDKs for distribution. 

The company will deal with this by releasing updates that will address the vulnerabilities. This will further reinforce the security of the chipset ecosystem as a whole. In addition to being aware of security updates, organizations and individual users must apply patches promptly to avoid potential issues. 

As a result, cybersecurity measures must be taken proactively to ensure that vulnerabilities cannot be exploited by cyber attackers, thus underlining the crucial importance of implementing proactive cybersecurity measures for all devices to protect data and systems from cyber threats.
