Android Framework Integer Overflow (CVE-2025-48595)

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) identified within the Android Framework. This flaw allows for the execution of arbitrary code, which could subsequently be used to achieve local privilege escalation on a compromised device.

Exposure and applicability

This vulnerability affects systems utilizing the Android Framework. Because the impact involves local privilege escalation, the primary exposure path requires an attacker or malicious process to already have a foothold on the device to trigger the overflow. Organizations managing fleets of Android devices or deploying custom Android-based infrastructure should identify all assets running affected framework versions.

Remediation priorities

Based on our analysis, vulnerability management teams should prioritize remediation according to the following hierarchy:

1. Vendor Patching: The primary corrective action is the application of mitigations provided by the vendor. This is the most direct method to address the underlying integer overflow.
2. Cloud Service Alignment: For organizations utilizing Android-based cloud services, alignment with BOD 22-01 guidance is recommended to ensure consistent exposure reduction across virtualized environments.
3. Decommissioning: In scenarios where vendor mitigations are unavailable or cannot be applied due to legacy constraints, the source suggests discontinuing use of the affected product to eliminate the risk.

How to validate remediation

Verification must move beyond simple version checks, as a deployed update does not always guarantee that the vulnerability is neutralized in the active runtime environment. We recommend the following validation approach:

• Configuration Audit: Confirm that the specific vendor-provided security updates associated with CVE-2025-48595 are successfully registered and active across the device fleet.
• Runtime Verification: Where possible, use authorized security tooling to verify that the framework is no longer susceptible to the specific integer overflow condition described in the vulnerability details.

Limits and open questions

It remains unknown whether this vulnerability has been utilized in known ransomware campaigns. Additionally, while vendor instructions provide a path to mitigation, there may be residual risk if the update process is interrupted or if custom framework modifications interfere with the patch application. Defenders should note that local privilege escalation vulnerabilities often depend on the presence of other vulnerabilities to achieve initial access; therefore, this fix reduces the impact of a compromise but does not prevent the initial entry.
