CVE-2025-32325 is a high-severity local privilege escalation vulnerability affecting multiple recent versions of the Google Android operating system (versions 13 through 16). The flaw exists in the appendFrom function within Parcel.cpp, where a heap buffer overflow can occur due to an out-of-bounds write. This vulnerability is classified under CWE-122 (Heap-based Buffer Overflow). Exploitation of this vulnerability allows an attacker with limited privileges (low privileges) on the device to escalate their privileges locally without requiring any additional execution privileges or user interaction. The vulnerability arises from improper bounds checking when appending data in the Parcel IPC mechanism, which is fundamental to Android's inter-process communication. An attacker could craft malicious input to trigger the heap overflow, corrupting memory and potentially gaining elevated privileges, thereby compromising the confidentiality, integrity, and availability of the device. The CVSS v3.1 base score is 7.8, reflecting high severity with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating local attack vector, low attack complexity, low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that this is a newly disclosed vulnerability requiring prompt attention. Given the critical role of Parcel in Android IPC, successful exploitation could allow attackers to bypass security controls, install persistent malware, or access sensitive data.

For European organizations, this vulnerability poses a significant risk especially for enterprises relying on Android devices for business operations, including mobile workforce, BYOD policies, and IoT deployments using Android-based systems. Exploitation could lead to unauthorized access to corporate data, escalation of privileges on devices, and potential lateral movement within corporate networks if compromised devices connect to internal resources. The high impact on confidentiality, integrity, and availability means sensitive information could be exfiltrated or manipulated, and device functionality disrupted. Critical sectors such as finance, healthcare, and government agencies in Europe, which often use Android devices for secure communications and operations, could face data breaches or operational disruptions. Additionally, the lack of required user interaction lowers the barrier for attackers to exploit the vulnerability, increasing the risk of automated or stealthy attacks. The absence of known exploits currently provides a window for mitigation but also underscores the urgency for organizations to proactively address the issue before active exploitation emerges.

European organizations should immediately prioritize the following actions: 1) Monitor official Google Android security advisories and update channels for patches addressing CVE-2025-32325 and apply them promptly once available. 2) Implement strict device management policies using Mobile Device Management (MDM) solutions to enforce timely OS updates and restrict installation of untrusted applications that could exploit this vulnerability. 3) Limit local access to Android devices by enforcing strong authentication mechanisms and restricting physical access, as the attack requires local access with low privileges. 4) Employ runtime protection and behavior monitoring tools on Android devices to detect anomalous activities indicative of exploitation attempts, such as unusual IPC calls or memory corruption behaviors. 5) Educate users and administrators about the risks of privilege escalation vulnerabilities and the importance of maintaining updated devices. 6) For critical environments, consider network segmentation and restricting Android device access to sensitive systems until patches are applied. 7) Conduct regular security assessments and penetration tests focusing on mobile device security to identify potential exploitation paths. These measures go beyond generic patching advice by emphasizing proactive device management, access control, and behavioral monitoring tailored to the nature of this vulnerability.
