CVE-2025-26444 is a vulnerability identified in Google Android versions 13 and 14, specifically within the VoiceInteractionManagerService component. The issue arises from a logic error in the onHandleForceStop method of VoiceInteractionManagerService.java. When a user-selected assistant application is forcibly stopped, the system incorrectly reverts to the default assistant application. Due to this flaw, the default assistant app is automatically granted the ROLE_ASSISTANT without requiring any additional execution privileges or user interaction. This unintended privilege escalation allows a local attacker with limited privileges to gain elevated rights, potentially enabling them to perform actions reserved for the assistant role, which may include accessing sensitive data, controlling device functions, or bypassing security controls. The vulnerability is classified under CWE-693, indicating improper logic in security decisions. The CVSS v3.1 base score is 7.8, reflecting high severity with local attack vector, low attack complexity, requiring privileges but no user interaction, and impacting confidentiality, integrity, and availability. Although no public exploits are known at this time, the flaw poses a significant risk due to the elevated privileges granted automatically and the lack of user interaction needed for exploitation. The vulnerability affects Android versions 13 and 14, which are widely deployed on modern devices. No official patches have been linked yet, but remediation will likely involve correcting the logic in the force-stop handling to prevent automatic role assignment. This vulnerability highlights the risks associated with improper handling of system roles and forced application stops in complex mobile OS components.

The impact of CVE-2025-26444 is substantial for organizations and individuals relying on affected Android versions. An attacker with local access and limited privileges can exploit this vulnerability to escalate their privileges to those of the assistant role, which typically has broad permissions on the device. This can lead to unauthorized access to sensitive user data, manipulation of device settings, interception or injection of voice commands, and potential control over other applications or system functions. The compromise of confidentiality, integrity, and availability can facilitate further attacks such as data exfiltration, persistent malware installation, or disruption of device operations. For enterprises, this could mean exposure of corporate data on mobile devices, undermining mobile device management (MDM) controls, and increasing the risk of insider threats or malware propagation. The lack of required user interaction lowers the barrier for exploitation, increasing the likelihood of successful attacks in environments where local access is possible, such as shared devices or compromised endpoints. Although no exploits are currently known in the wild, the vulnerability's high severity and broad impact on core system functionality make it a critical concern for Android users globally.

To mitigate CVE-2025-26444, organizations and users should: 1) Monitor for official patches or updates from Google and apply them promptly once released to correct the logic error in VoiceInteractionManagerService. 2) Restrict local device access to trusted users only, as exploitation requires local privileges. 3) Employ strong device lock mechanisms (PIN, biometric) to prevent unauthorized physical access. 4) Use mobile device management (MDM) solutions to enforce security policies and monitor for unusual assistant role assignments or app behavior. 5) Disable or limit the use of assistant applications where feasible, especially in high-security environments. 6) Audit installed assistant apps and remove any unnecessary or untrusted ones to reduce attack surface. 7) Educate users about the risks of granting assistant roles and the importance of device security hygiene. 8) Implement runtime monitoring or endpoint detection tools capable of identifying privilege escalations or anomalous role changes related to assistant apps. These measures, combined with timely patching, will reduce the risk and impact of exploitation.
