CVE-2025-32325 is a local privilege escalation vulnerability identified in the Android operating system, specifically affecting versions 13 through 16. The flaw exists in the appendFrom function within Parcel.cpp, where an out-of-bounds write occurs due to a heap buffer overflow. This vulnerability allows an attacker with local access to the device to overwrite memory beyond the intended buffer boundaries. Such a memory corruption can lead to elevation of privileges without requiring any additional execution privileges or user interaction. The vulnerability is exploitable purely through local code execution, meaning an attacker or malicious app already running on the device can leverage this flaw to gain higher privileges, potentially escalating from a limited user context to system or root level access. This could enable the attacker to bypass security controls, access sensitive data, install persistent malware, or alter system configurations. The absence of user interaction requirements increases the risk as exploitation can be automated or triggered silently. Although no known exploits are currently reported in the wild, the vulnerability's nature and impact make it a significant threat to Android devices, especially those running the affected versions. The lack of a CVSS score indicates that the vulnerability is newly published and may not yet have undergone full severity assessment.

For European organizations, the impact of CVE-2025-32325 could be substantial, particularly for those relying on Android devices for business operations, mobile workforce, or IoT deployments. Successful exploitation could allow attackers to gain elevated privileges on employee or corporate devices, leading to unauthorized access to corporate networks, sensitive data leakage, or deployment of persistent malware. This is especially critical for sectors handling sensitive personal data or intellectual property, such as finance, healthcare, and government agencies. The vulnerability's local exploitation vector means that attackers would need some initial foothold on the device, such as through a malicious app or compromised software update. However, once exploited, the attacker could bypass Android's sandboxing and permission models, undermining device integrity and confidentiality. This could facilitate lateral movement within corporate networks or enable espionage activities. Moreover, given the widespread use of Android devices across Europe, the scale of potential impact is large. The lack of user interaction requirement further increases the risk of stealthy exploitation, complicating detection and response efforts.

To mitigate CVE-2025-32325, European organizations should prioritize the following actions: 1) Ensure timely deployment of security patches from Google or device manufacturers as soon as they become available, as this vulnerability affects core Android system components. 2) Implement strict application vetting policies to prevent installation of untrusted or malicious apps that could exploit local vulnerabilities. 3) Employ mobile device management (MDM) solutions to enforce security configurations, restrict app installations, and monitor device behavior for signs of compromise. 4) Limit the use of privileged or root access on devices to reduce the attack surface and potential impact of privilege escalation. 5) Educate users about the risks of installing apps from unofficial sources and encourage adherence to security best practices. 6) For organizations deploying Android-based IoT or embedded systems, conduct thorough security assessments and isolate such devices within segmented network zones to contain potential breaches. 7) Monitor device logs and security alerts for anomalous activities indicative of exploitation attempts. These targeted measures go beyond generic advice by focusing on controlling local access vectors and enforcing strict device management policies.
