What the vulnerability is
CVE-2025-48633 is an information disclosure vulnerability located within the Android Framework. According to CISA, this flaw allows for the unauthorized disclosure of unspecified information. The vulnerability was added to CISA’s Known Exploited Vulnerabilities (KEV) catalog on December 2, 2025, indicating that it has been observed in active exploitation.
Exposure and applicability
This vulnerability is applicable to healthcare providers, health plans, and business associates that deploy Android-based mobile devices. In a clinical environment, these devices are frequently used for accessing electronic Protected Health Information (ePHI), managing patient workflows, or operating integrated medical applications. Because the flaw resides in the framework level of the operating system, any device running an affected version of the Android Framework could be susceptible to information disclosure, potentially compromising the confidentiality of data handled on the device.
Remediation priorities
Based on the inclusion of this vulnerability in the KEV catalog, we analyze the following priority actions for healthcare security leaders:
- Inventory and Patching: Identify all Android-managed devices within the clinical environment. Prioritize the application of vendor-supplied security updates to the Android Framework. This is a primary control intended to prevent initial exploitation.
- Cloud Service Review: For organizations utilizing cloud-based mobile device management (MDM) or virtualized Android environments, review configurations in alignment with BOD 22-01 guidance to ensure that cloud-level controls are not introducing additional exposure.
- Endpoint Decommissioning: In scenarios where a legacy device is critical for clinical operations but the vendor no longer provides security updates for this vulnerability, evaluate the risk of continued use versus the operational impact of discontinuing the product.
How to validate remediation
To verify that the risk has been reduced, organizations should employ the following methods:
- Version Verification: Security administrators can audit device fleet manifests via MDM consoles to confirm that the installed Android security patch level meets or exceeds the version containing the fix for CVE-2025-48633.
- Configuration Audit: Review cloud service logs and configurations to ensure that mitigations recommended by the vendor have been successfully deployed across the environment.
It is important to note that verifying a version number confirms the update was applied, but it does not guarantee that all possible exploitation vectors are eliminated.
Limits and open questions
The specific nature of the information being disclosed remains unspecified in the available source data. Consequently, it is currently unknown exactly what types of data—such as system logs, memory contents, or user credentials—could be exposed. Additionally, while CISA has flagged this for exploitation, there is no confirmed data regarding its use in known ransomware campaigns targeting the healthcare sector. Organizations should remain aware that residual risk persists if devices are not updated promptly or if vendor patches are unavailable for specific hardware models.
