CVE-2025-48635 is a vulnerability identified in Google Android operating system versions 14 and 15, specifically within the TaskFragmentOrganizerController.java source code. The issue arises from a logic error that causes an unintended leak of activity tokens, which are sensitive identifiers used to manage and control activity lifecycle and permissions within the Android framework. This token leak can be exploited by a local attacker to escalate privileges on the device without needing any prior elevated execution rights or user interaction, making the attack vector purely local and stealthy. The vulnerability is categorized under CWE-693 (Protection Mechanism Failure), CWE-532 (Information Exposure Through Log Files), and CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor), indicating that sensitive information leakage leads to a breakdown in security controls. The CVSS v3.1 base score is 7.7, reflecting high severity due to the high impact on confidentiality and integrity, low attack complexity, and no requirement for privileges or user interaction. Although no public exploits have been observed in the wild, the vulnerability poses a significant risk to Android devices running the affected versions. The absence of patch links suggests that fixes may still be pending or in development, emphasizing the need for vigilance and interim mitigations.

If exploited, this vulnerability allows a local attacker to gain elevated privileges on affected Android devices, potentially enabling unauthorized access to sensitive data and control over system components. The confidentiality and integrity of the device can be severely compromised, allowing attackers to bypass security restrictions and possibly install malicious software or manipulate system behavior. Since no user interaction is required, the attack can be automated or triggered silently, increasing the risk of unnoticed exploitation. This could affect personal users, enterprises relying on Android devices for secure communications, and sectors where device integrity is critical, such as finance, healthcare, and government. The lack of known exploits in the wild currently limits immediate widespread impact, but the vulnerability remains a significant threat once weaponized.

Organizations and users should monitor official Google Android security bulletins for patches addressing CVE-2025-48635 and apply updates promptly once available. Until patches are released, enforcing strict local access controls is critical to prevent untrusted local users or applications from exploiting the vulnerability. This includes disabling or restricting installation of untrusted apps, enforcing strong device lock mechanisms, and using mobile device management (MDM) solutions to control app permissions and monitor for suspicious activity. Developers should audit code interacting with activity tokens to ensure proper handling and avoid logic errors that could leak sensitive information. Additionally, employing runtime application self-protection (RASP) and endpoint detection and response (EDR) tools on Android devices can help detect anomalous privilege escalation attempts. Regular security training for users about the risks of installing untrusted applications and the importance of device updates will also reduce exposure.
