Executive Summary

CVE-2025-26436 is a security vulnerability in the Android platform where the method clearAllowBgActivityStarts in PendingIntentRecord.java does not fully clear all background activity launch (BAL) allowlist entries. Specifically, it removes associated tokens but fails to clear duration-based entries, which could allow an application to launch an activity from the background without user interaction. This leads to a possible local escalation of privilege without needing additional execution privileges. [1]

Impact Analysis

This vulnerability could allow a malicious application to start activities from the background without user interaction, bypassing background activity launch restrictions. This can lead to local privilege escalation on the device, potentially enabling unauthorized actions or access to sensitive functions without additional permissions. [1]

Mitigation Strategies

To mitigate this vulnerability, ensure that your Android system is updated with the patch that fixes CVE-2025-26436. The fix involves updating the Android framework base code, specifically the PendingIntentRecord.java file, to properly clear all allowlist entries related to Background Activity Launch privileges. Applying the official security update from Android that includes this patch will prevent unauthorized background activity starts and local privilege escalation. [1]
