CVE-2025-32312 is a high-severity 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. Specifically, this vulnerability arises from the improper handling of serialized data bundles, enabling maliciously crafted data to be passed to subsequent processes without proper validation or sanitization. This unsafe deserialization (classified under CWE-502) can lead to local privilege escalation, allowing an attacker with limited privileges to gain higher-level access on the affected device. Notably, exploitation does not require user interaction or additional execution privileges, making it easier for an attacker who already has some local access to escalate their privileges. The CVSS v3.1 base score is 7.8, reflecting the high impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and no user interaction required. Although no known exploits are currently reported in the wild, the vulnerability’s nature and ease of exploitation make it a significant risk for Android devices running the affected versions. The absence of published patches at this time further increases the urgency for mitigation and monitoring.

For European organizations, this vulnerability poses a substantial risk, especially for enterprises and government agencies that rely on Android devices for daily operations, secure communications, and access to sensitive information. Successful exploitation could allow attackers to escalate privileges locally on devices, potentially leading to unauthorized access to confidential data, installation of persistent malware, or disruption of device functionality. This could compromise the integrity of corporate mobile environments, lead to data breaches, and undermine trust in mobile device security. Given the widespread use of Android devices across Europe in both consumer and enterprise contexts, the vulnerability could affect a broad range of sectors including finance, healthcare, public administration, and critical infrastructure. The lack of user interaction requirement means that automated or stealthy attacks are feasible, increasing the threat to organizations with less stringent endpoint security controls. Furthermore, local privilege escalation can serve as a stepping stone for lateral movement within corporate networks, amplifying the potential damage.

To mitigate this vulnerability effectively, European organizations should: 1) Prioritize updating Android devices to patched versions as soon as Google releases security updates addressing CVE-2025-32312. Until patches are available, restrict installation of untrusted applications and enforce strict app vetting policies to reduce the risk of malicious payloads exploiting unsafe deserialization. 2) Implement Mobile Device Management (MDM) solutions that can enforce security policies, monitor device integrity, and remotely disable or wipe compromised devices. 3) Employ application whitelisting and sandboxing techniques to limit the impact of any local privilege escalation by isolating critical applications and data. 4) Educate users and IT staff about the risks of privilege escalation vulnerabilities and encourage vigilance against suspicious device behavior or unauthorized access attempts. 5) Monitor device logs and security telemetry for unusual activity indicative of exploitation attempts, such as unexpected privilege changes or abnormal process behavior. 6) Limit physical access to devices and enforce strong authentication mechanisms to reduce the likelihood of attackers gaining initial local access required to exploit this vulnerability.
