CVE-2025-32312 is a local elevation of privilege vulnerability affecting Google Android versions 13, 14, and 15. The flaw exists in the createIntentsList method of the PackageParser.java component, where unsafe deserialization allows an attacker to bypass lazy bundle hardening protections. Lazy bundle hardening is a security mechanism designed to prevent tampering with serialized data passed between processes. However, due to improper handling in this method, an attacker can craft modified data that is deserialized unsafely, enabling them to escalate privileges locally without requiring any additional execution privileges or user interaction. This means that a malicious app or process with limited permissions on the device could exploit this vulnerability to gain higher privileges, potentially accessing or modifying sensitive system components or data. The vulnerability does not require the attacker to have elevated privileges initially, nor does it require the victim to perform any action, making it particularly dangerous in environments where untrusted or malicious apps may be installed. Although no known exploits are currently reported in the wild, the vulnerability's nature and the affected Android versions indicate a significant risk to device security until patched. No CVSS score has been assigned yet, and no official patches or mitigation links have been published at the time of this report.

For European organizations, the impact of CVE-2025-32312 could be substantial, especially for those relying on Android devices for business operations, secure communications, or mobile workforce management. The elevation of privilege vulnerability allows attackers to bypass security boundaries on affected devices, potentially leading to unauthorized access to sensitive corporate data, interception of communications, or installation of persistent malware with elevated rights. This could compromise confidentiality, integrity, and availability of organizational data and services accessed via Android devices. Enterprises with Bring Your Own Device (BYOD) policies or those deploying Android-based mobile device management (MDM) solutions are particularly at risk. Furthermore, sectors such as finance, healthcare, and government agencies in Europe that handle sensitive personal or classified information could face regulatory and compliance repercussions if devices are compromised. The lack of user interaction needed for exploitation increases the risk of widespread compromise, especially in environments where device usage policies are less stringent or where users may install untrusted applications. The vulnerability also poses a risk to Android-based IoT devices used in industrial or critical infrastructure settings, which are increasingly common in European smart cities and manufacturing.

To mitigate the risk posed by CVE-2025-32312, European organizations should take the following specific actions: 1) Immediately monitor for official security patches or updates from Google and Android device manufacturers and prioritize deployment of these patches across all affected devices (Android 13, 14, and 15). 2) Implement strict application whitelisting and restrict installation of apps from untrusted sources to reduce the likelihood of malicious apps exploiting this vulnerability. 3) Employ mobile threat defense (MTD) solutions that can detect anomalous behavior indicative of privilege escalation attempts. 4) Enforce least privilege principles on Android devices, limiting app permissions and disabling unnecessary services that could be leveraged in exploitation. 5) Conduct regular security audits and vulnerability assessments on mobile device fleets to identify unpatched or vulnerable devices. 6) Educate users about the risks of installing unauthorized applications and the importance of timely updates. 7) For organizations using Android-based IoT devices, isolate these devices on segmented networks and monitor for unusual activity. 8) Consider deploying endpoint detection and response (EDR) tools capable of monitoring Android devices for exploitation attempts. These measures, combined with rapid patch management, will help reduce the attack surface and limit potential exploitation.
