CVE-2025-48538 is a vulnerability identified in the Android operating system, specifically within the PackageManagerService component's setApplicationHiddenSettingAsUser function. This function is responsible for managing the visibility state of applications for different users on the device. The vulnerability arises due to improper input validation, which allows an attacker to hide a system-critical package. By exploiting this flaw, an attacker can cause a local denial of service (DoS) condition. The denial of service occurs because hiding a critical system package can disrupt essential system operations or services that depend on that package, potentially leading to system instability or failure to perform critical functions. Notably, exploitation of this vulnerability does not require any additional execution privileges beyond local access, nor does it require any user interaction, making it easier for an attacker with local access to trigger the issue. The affected Android versions include 13, 14, 15, and 16, indicating that this vulnerability impacts a broad range of recent Android releases. There are no known exploits in the wild at the time of publication, and no official patches or fixes have been linked yet. The lack of a CVSS score means that the severity must be assessed based on the technical details provided. Given the nature of the vulnerability, it is a local privilege-independent denial of service that can affect device availability by hiding critical system packages, potentially causing system malfunction or degraded performance.

For European organizations, the impact of CVE-2025-48538 can be significant, especially for those relying heavily on Android devices for business operations, including mobile workforce management, secure communications, and application deployment. A denial of service on Android devices can disrupt employee productivity and potentially impact critical business processes if essential applications or system services become unavailable. Since the vulnerability does not require elevated privileges or user interaction, it poses a risk in environments where devices might be accessible to untrusted users or where malware with local access could exploit this flaw. This could be particularly problematic in sectors such as finance, healthcare, and government, where device availability and integrity are crucial. Additionally, organizations that deploy custom Android builds or use Android devices in embedded or IoT contexts might face operational disruptions. The absence of known exploits in the wild currently limits immediate risk, but the potential for future exploitation remains, especially if attackers develop automated tools to leverage this vulnerability.

To mitigate CVE-2025-48538, European organizations should take several specific steps beyond generic advice: 1) Monitor for official patches or updates from Google and device manufacturers and prioritize their deployment across all affected Android devices. 2) Implement strict access controls to limit local access to Android devices, reducing the risk of exploitation by unauthorized users. 3) Use Mobile Device Management (MDM) solutions to enforce security policies, monitor device health, and detect anomalous behavior that might indicate attempts to exploit this vulnerability. 4) Restrict installation of untrusted applications and enforce application whitelisting to prevent malicious apps from gaining local access. 5) Educate users about the risks of leaving devices unattended or accessible to untrusted individuals, as local access is required for exploitation. 6) For organizations using custom Android builds or embedded Android devices, conduct thorough code reviews and testing to identify and remediate similar input validation issues. 7) Prepare incident response plans that include procedures for handling denial of service conditions on mobile devices to minimize operational impact.
