CVE-2024-49731 is a vulnerability identified in Google Android 13 specifically affecting Pixel Watch devices. The root cause is a logic error in the code managing telemetry opt-in settings during the setup process of a new Pixel Watch. This error can cause corruption of telemetry opt-in settings on other watches linked to the same user or environment. The vulnerability allows a local attacker with physical access and requiring user interaction to escalate privileges on the device without needing additional execution privileges. The flaw is categorized under CWE-266, indicating improper access control, which means the system fails to enforce correct permissions when modifying telemetry settings. Although the impact is limited to local privilege escalation, it could enable unauthorized changes to telemetry data collection preferences, potentially affecting user privacy and device behavior. The CVSS 3.1 base score is 4.0 (medium), reflecting the need for local access and user interaction, and limited confidentiality impact. No patches or known exploits are currently available, but the vulnerability is publicly disclosed and should be addressed promptly. This issue highlights the importance of rigorous logic validation in device setup processes, especially for IoT and wearable devices where multiple linked devices coexist.

The primary impact of CVE-2024-49731 is local elevation of privilege on Pixel Watch devices running Android 13. An attacker with physical access and the ability to interact with the device could manipulate telemetry opt-in settings on other watches, potentially bypassing user consent mechanisms. While this does not directly compromise confidentiality, integrity, or availability of sensitive data or system functions broadly, it undermines user control over telemetry data collection and could lead to privacy violations. Organizations relying on Pixel Watches for workforce management, health monitoring, or secure environments may face risks of unauthorized configuration changes. The scope is limited to devices running the affected Android version and specifically Pixel Watches, reducing the overall attack surface. However, the requirement for user interaction and local access lowers the likelihood of widespread exploitation. The absence of known exploits in the wild suggests limited current threat but does not preclude future attacks once exploit code becomes available.

To mitigate CVE-2024-49731, organizations and users should: 1) Monitor for official patches or firmware updates from Google specifically addressing this vulnerability and apply them promptly once released. 2) Restrict physical access to Pixel Watch devices to trusted individuals to prevent unauthorized local exploitation. 3) Educate users to be cautious during the setup of new Pixel Watches, especially when multiple devices are linked, to avoid inadvertent privilege escalation scenarios. 4) Implement device management policies that limit telemetry configuration changes to authorized administrators or through secure management channels. 5) Consider disabling telemetry features if not required or if privacy concerns outweigh benefits, reducing the attack surface. 6) Employ endpoint security solutions that can detect anomalous local privilege escalation attempts or unauthorized configuration changes on wearable devices. 7) Maintain an inventory of affected devices and monitor for unusual behavior related to telemetry settings. These steps go beyond generic advice by focusing on device-specific controls and user interaction awareness.
