CVE-2025-10502 is a heap buffer overflow vulnerability identified in the ANGLE graphics engine component used by Google Chrome browsers prior to version 140.0.7339.185. ANGLE (Almost Native Graphics Layer Engine) is responsible for translating OpenGL ES calls to platform-specific graphics APIs, making it a critical part of Chrome's rendering pipeline. The vulnerability arises from improper handling of heap memory, which can be corrupted when processing specially crafted network traffic. An attacker can exploit this flaw remotely by enticing a user to visit a maliciously crafted website or interact with malicious content, triggering heap corruption that may lead to arbitrary code execution within the browser context. The vulnerability does not require any prior authentication but does require user interaction, such as clicking a link or loading a web page. The CVSS v3.1 base score of 8.8 reflects the high impact on confidentiality, integrity, and availability, with an attack vector over the network, low attack complexity, no privileges required, and user interaction needed. Although no active exploits have been reported in the wild, the potential for exploitation is significant given Chrome's widespread use. The vulnerability underscores the importance of secure memory management in browser components that handle complex graphics operations and network data parsing.

The exploitation of CVE-2025-10502 can have severe consequences for organizations worldwide. Successful attacks could lead to arbitrary code execution within the context of the browser, enabling attackers to steal sensitive information, install malware, or pivot to internal networks. The compromise of confidentiality, integrity, and availability can disrupt business operations, lead to data breaches, and damage organizational reputation. Given Chrome's dominant market share globally, a large number of users and enterprises are potentially exposed. Attackers could leverage this vulnerability in targeted attacks or widespread campaigns to compromise endpoints, especially in environments where patching is delayed. The requirement for user interaction limits automated exploitation but does not eliminate risk, as phishing and social engineering remain effective vectors. The vulnerability is particularly critical for sectors relying heavily on web applications and remote browsing, such as finance, government, and critical infrastructure.

To mitigate CVE-2025-10502, organizations should immediately update all affected Chrome browsers to version 140.0.7339.185 or later, where the vulnerability is patched. Beyond patching, network-level defenses can help reduce exposure by filtering or blocking suspicious traffic patterns that may carry exploit payloads targeting the ANGLE component. Implementing browser security policies that restrict or sandbox web content can limit the impact of successful exploitation. User education to recognize phishing attempts and avoid interacting with untrusted links or websites is essential to reduce the risk of triggering the vulnerability. Monitoring browser behavior for anomalies such as unexpected crashes or unusual memory usage can provide early detection of exploitation attempts. Organizations should also consider deploying endpoint detection and response (EDR) solutions capable of identifying exploit techniques targeting browser memory corruption. Regular vulnerability scanning and penetration testing can help ensure that Chrome installations remain up to date and resilient against emerging threats.
