CVE-2025-20632 is a high-severity vulnerability affecting Mediatek's Software Development Kit. The vulnerability arises from a possible out-of-bounds write due to an incorrect bounds check in the wlan AP driver. This could lead to local escalation of privilege, with no additional execution privileges required. Importantly, user interaction is not necessary for exploitation, making it a significant risk for organizations.
With a CVSS score of 7.8, this vulnerability poses a high threat level. The potential for local privilege escalation represents a serious risk to the integrity and confidentiality of affected systems. Organizations leveraging the Mediatek Software Development Kit should prioritize addressing this vulnerability to mitigate associated risks.
The urgency for remediation is further emphasized by the lack of known exploits or public proof of concept at this time. However, given the nature of the flaw and its potential impact, organizations should act swiftly to patch this vulnerability.
Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability is classified as CWE-787, indicating an out-of-bounds write. The issue was published on February 3, 2025, and affects the Software Development Kit from Mediatek. The official description notes that the vulnerability could lead to local privilege escalation without requiring execution privileges, making it critical for organizations using affected products to take immediate action.
Technical Analysis
The root cause of this vulnerability is an incorrect bounds check in the wlan AP driver, which allows for a possible out-of-bounds write. The attack vector is local, meaning that an attacker must have access to the affected system. The attack complexity is considered low, and the privileges required are also low, meaning that even users with minimal access could exploit this vulnerability. User interaction is not required, further increasing the risk.
The potential impact includes high confidentiality, integrity, and availability impacts due to the nature of the privilege escalation. If exploited, this could result in unauthorized access to sensitive data and system controls.
Risk & Impact Analysis
The real-world risk associated with CVE-2025-20632 is significant. Organizations that utilize the Mediatek Software Development Kit should recognize the potential for local privilege escalation, which could allow attackers to gain higher-level access and control over systems. The urgency for remediation is underscored by the high CVSS score of 7.8, indicating a serious vulnerability that could lead to severe consequences.
Organizations should address in priority patch cycle. The potential blast radius for this vulnerability extends to any system using the affected Software Development Kit, highlighting the need for immediate action.
