CVE-2025-48642: Google Android Information Disclosure Flaw

CVE-2025-48642 Overview

CVE-2025-48642 is an information disclosure vulnerability affecting Google Android devices. The vulnerability exists in the jump_to_payload function within the payload.rs file and stems from a logic error in the code. This flaw enables local information disclosure without requiring any additional execution privileges or user interaction for exploitation.

Critical Impact

Local information disclosure vulnerability in Android that allows attackers with local access to extract sensitive data without user interaction, potentially exposing confidential system or user information.

Affected Products

• Google Android 14.0
• Google Android 15.0
• Google Android 16.0 (including QPR2 Beta 1, Beta 2, and Beta 3)

Technical Details for CVE-2025-48642

Vulnerability Analysis

This vulnerability falls under the category of Information Disclosure (CWE-200), where sensitive information is exposed to unauthorized actors. The flaw resides in the jump_to_payload function implemented in payload.rs, a Rust-based component within the Android platform. A logic error in this code path allows local processes to access information they should not have access to.

The vulnerability requires local access to exploit but does not need elevated privileges beyond what a normal local user would possess. The impact is limited to confidentiality, with no direct effect on system integrity or availability. Attackers can leverage this vulnerability to extract sensitive data from the device, which could include system configuration details, user data, or other protected information.

Root Cause

The root cause of CVE-2025-48642 is a logic error within the jump_to_payload function in payload.rs. This programming mistake results in improper handling of data or control flow, leading to unintended information exposure. The error likely involves incorrect conditional checks, improper bounds validation, or flawed state management that allows information to leak to unauthorized callers.

Attack Vector

The attack vector for this vulnerability is local, meaning an attacker must have some form of access to the target Android device to exploit it. The exploitation does not require any special privileges beyond local access, nor does it require user interaction. This makes the vulnerability particularly concerning for scenarios involving:

• Malicious applications installed on the device
• Compromised user accounts with local access
• Physical access to an unlocked device
• Other malware or attack chains that provide local execution capability

The vulnerability exploits a logic flaw in the payload handling code, allowing an attacker to trigger information disclosure through normal system interactions with the affected component.

Detection Methods for CVE-2025-48642

Indicators of Compromise

• Unusual access patterns to the payload.rs component or related payload handling functions
• Unexpected local processes attempting to access protected system information
• Anomalous read operations from sensitive data locations that correlate with payload execution

Detection Strategies

• Monitor Android system logs for unusual activity related to payload processing components
• Implement behavioral analysis to detect applications attempting to access information outside their normal scope
• Deploy endpoint detection solutions that can identify exploitation attempts targeting known Android vulnerabilities

Monitoring Recommendations

• Enable enhanced logging on Android devices for security-critical components
• Utilize SentinelOne's mobile threat defense capabilities to monitor for suspicious local information access patterns
• Review application permissions and behaviors for signs of data exfiltration attempts

How to Mitigate CVE-2025-48642

Immediate Actions Required

• Apply the Android security updates from the March 2026 security bulletin immediately
• Review installed applications for potentially malicious software that could exploit this vulnerability
• Limit physical access to affected devices until patches are applied
• Consider isolating sensitive data on affected devices until remediation is complete

Patch Information

Google has addressed this vulnerability in the Android Security Bulletin March 2026. Users and administrators should apply the security patch level 2026-03-01 or later to remediate this vulnerability. The patch corrects the logic error in the jump_to_payload function, preventing unauthorized information disclosure.

Workarounds

• Restrict installation of untrusted applications to reduce the attack surface for local exploitation
• Enable Android's built-in security features such as Google Play Protect to detect potentially harmful applications
• For enterprise environments, implement Mobile Device Management (MDM) policies to enforce security updates and restrict application installations

# Verify Android security patch level
adb shell getprop ro.build.version.security_patch
# Expected output: 2026-03-01 or later
