Historical catalog analysis: CISA added this entry on June 02, 2026. The entry reflects catalog information retrieved on August 31, 2026, not a snapshot archived on the inclusion date. Check current vendor guidance before acting.
What the vulnerability is
CVE-2025-48595 is an integer overflow vulnerability (CWE-190) located within the Android Framework. According to CISA, this flaw could allow for code execution that may lead to local privilege escalation. This means an attacker or a malicious application already present on the device could potentially gain higher-level permissions than intended.
Exposure and applicability
This vulnerability is relevant to U.S. healthcare providers and business associates who utilize Android-based systems in clinical environments. Applicability extends to:
* Mobile Clinical Applications: Tablets or smartphones used by clinicians for accessing ePHI or managing patient records.
* Medical Device Interfaces: Integrated medical hardware that utilizes the Android Framework for its user interface or operational control.
* Managed Mobile Endpoints: Corporate-owned devices issued to healthcare staff for communication and coordination.
Because this is a local privilege escalation vulnerability, it typically requires an initial foothold on the device to be exploited. However, its inclusion in CISA’s Known Exploited Vulnerabilities catalog indicates that the flaw has been observed in active use, increasing the risk profile for unpatched devices.
Remediation priorities
Our analysis suggests prioritizing remediation based on the device’s proximity to sensitive patient data and its role in clinical continuity. We recommend the following actions:
- Inventory Android Assets: Identify all devices running the Android Framework, specifically those used for ePHI access or medical device control. This should be led by Clinical Engineering or IT Asset Management.
- Apply Vendor Mitigations: Deploy security updates provided by the device manufacturer to address the integer overflow. For cloud-integrated services, follow applicable BOD 22-01 guidance where relevant.
- Evaluate Legacy Hardware: If a device is no longer supported by the vendor and no mitigation exists for CVE-2025-48595, evaluate whether the device should be discontinued or isolated from the clinical network to prevent potential escalation paths.
How to validate remediation
To verify that exposure has been reduced, security leaders should employ the following methods:
* Version Verification: Confirm through mobile device management (MDM) tools or system settings that the installed security patch level matches or exceeds the vendor’s recommended version for this CVE.
* Configuration Audit: For devices where patching is delayed, verify that restrictive application permissions are in place to limit the ability of untrusted apps to execute code locally.
Note: Version checks indicate a patch has been applied but do not guarantee total immunity from all exploitation vectors.
Limits and open questions
It remains unknown whether this vulnerability has been utilized specifically in ransomware campaigns. Additionally, while CISA established a remediation deadline of June 5, 2026, for federal agencies, this date serves as a risk indicator rather than a legal mandate for private healthcare entities.
There is residual risk associated with medical devices where vendor updates may lag behind general Android releases. In these cases, clinical engineering must coordinate with vendors to ensure that patches do not interfere with the intended medical functionality of the device.
