Android Framework default speech recognizer privilege escalation

IdentifiersCVE-2025-48629CWE-276

CVE-2025-48629 is an Android Framework elevation-of-privilege vulnerability in findAvailRecognizer within VoiceInteractionManagerService.java. According to the provided description, the issue is caused by an insecure default value that can allow an attacker-controlled application to become the default speech recognizer app. This improper default selection behavior can let a local attacker obtain a more privileged role in the voice interaction/speech recognition trust boundary than intended, resulting in privilege escalation without requiring additional execution privileges or user interaction.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can allow a local attacker application to become the default speech recognizer app and thereby gain elevated privileges associated with that role. The provided content characterizes the outcome as local escalation of privilege. No user interaction is required, which increases exploitability for a malicious app already present on the device.

Mitigation

If you can’t patch tonight, do this now.

Until the patch is applied, reduce exposure by limiting installation of untrusted local applications, enforcing application allowlisting where possible, and prioritizing rapid deployment of the December 2025 Android security update or vendor-equivalent firmware. Because exploitation does not require user interaction, mitigation is primarily patch-driven; the provided content does not describe a specific configuration workaround for disabling the affected behavior.

Remediation

Patch, then assume compromise.

Apply the Android security updates that address CVE-2025-48629 in the December 2025 Android Security Bulletin. The supporting content states that devices updated to the 2025-12-05 patch level are fully remediated for issues disclosed in that bulletin. OEM and downstream vendors should integrate the corresponding Framework fix for VoiceInteractionManagerService.java.
