Android 0-Day Vulnerability warnings intensified as CISA added two Android Framework flaws to the CISA Known Exploited Vulnerabilities catalog. The agency confirmed active exploitation.
The vulnerabilities affect Android OS devices globally, with risk of privilege escalation and data exposure. Google is limiting technical detail until patches propagate.
CISA listed the CVEs on December 2, 2025 and set a December 23, 2025 remediation deadline for U.S. federal agencies under BOD 22-01.
Android 0-Day Vulnerability: What You Need to Know
- Two actively exploited Android Framework flaws added to CISA KEV require rapid patching before December 23, 2025.
Active Exploitation of Android Framework Flaws
CISA added two Android Framework bugs to the KEV catalog: CVE-2025-48572 for privilege escalation and CVE-2025-48633 for information disclosure.
The additions confirm in‑the‑wild use, elevating the Android 0-Day Vulnerability to a high-priority risk for mobile fleets. Google is withholding deeper technical specifics to reduce copycat attacks until updates are broadly available.
Successful privilege escalation can allow malware installation, unrestricted data access, and persistence. Unpatched devices risk multi‑stage attack chains that impact device integrity and user privacy.
For recent context on related risks and patch cadence, see Google’s prior advisories on January 2025 Android update for critical bugs and Android vulnerabilities disclosed in March 2025.
CVE Details and Exploit Status
CVE-2025-48572 Android Privilege Escalation could grant attackers elevated permissions on vulnerable devices. CVE-2025-48633 enables information disclosure through the same framework component and may expose sensitive data without user interaction.
Exploitation is active, though no ransomware linkage is confirmed at this time. This Android 0-Day Vulnerability remains a credible vector for spyware and data theft, aligning with recent reports of Android-targeting campaigns such as Firescam Android spyware.
CISA Known Exploited Vulnerabilities Requirements
Placement in the CISA Known Exploited Vulnerabilities catalog triggers mandatory action for federal agencies under Binding Operational Directive 22-01. CISA added both CVEs on December 2, 2025 and set December 23, 2025 as the deadline for remediation or mitigations.
Organizations should track official guidance here: CISA Known Exploited Vulnerabilities and CISA BOD 22-01. Treat the Android 0-Day Vulnerability as a priority across managed and BYOD devices.
Mitigation Guidance for Users and Enterprises
Apply vendor patches and mitigations as soon as they are released. Where updates are unavailable, consider discontinuing affected devices or using compensating controls.
- Enable automatic OTA security updates and check Google Play system updates for pending patches.
- Prioritize monthly Android security updates across corporate fleets and communicate timelines to users.
- Monitor for indicators of compromise tied to these CVEs and investigate anomalies promptly.
- Segment networks to limit lateral movement and rehearse mobile incident response runbooks.
- Focus triage on high‑risk users, unmanaged endpoints, and devices lacking recent patches.
For status updates and patch availability, consult the Android Security Bulletin.
Detection and Hardening for Mobile Fleets
Security teams should correlate EDR, MDM, and network telemetry to spot unusual framework calls, privilege escalation attempts, or suspicious inter‑process behavior.
Enforce least privilege, vet apps rigorously, and orchestrate rapid patch deployment to reduce the blast radius of any Android 0-Day Vulnerability exposure. Proactive control baselines help contain exploitation while patches roll out.

Implications for Organizations and Mobile Users
Inclusion in KEV provides authoritative validation, standardized timelines, and clear prioritization for remediation. This transparency helps security teams direct resources toward urgent patching, monitoring, and temporary hardening controls where the Android 0-Day Vulnerability has operational impact.
Active exploitation increases the chance of compromise before updates reach fragmented device ecosystems. Enterprises must balance uptime with accelerated fixes, especially where legacy Android devices, regional OEM variants, or unmanaged endpoints complicate update pipelines tied to the Android 0-Day Vulnerability.
Conclusion
CISA’s action confirms real‑world exploitation of Android Framework flaws and elevates the Android 0-Day Vulnerability to a top-tier patching priority. Federal agencies face a December 23 deadline.
Apply patches and mitigations immediately, expand monitoring for abuse, and segment networks to contain incidents. Where patching lags, deploy compensating controls or consider decommissioning at‑risk devices.
Clear communication with users, disciplined update processes, and focused telemetry can limit the impact of the Android 0-Day Vulnerability across diverse mobile environments.
Questions Worth Answering
What did CISA change in the KEV catalog?
CISA added CVE-2025-48572 and CVE-2025-48633 to the KEV, confirming active exploitation and setting a December 23, 2025 federal remediation deadline.
Which devices are at risk?
Android OS devices. Exposure varies by OEM model, patch level, and update cadence. Enable automatic updates and install patches promptly.
What is the Android 0-Day Vulnerability in this case?
Two exploited Android Framework bugs, one enabling privilege escalation, one enabling information disclosure, now listed in CISA Known Exploited Vulnerabilities.
Is there evidence of ransomware use?
No direct confirmation. Exploitation is active and consistent with spyware, data theft, and persistence techniques.
What should enterprises do now?
Patch immediately, enforce EDR/MDM monitoring, segment networks, and apply compensating controls where patching is delayed.
Where can I track patch status?
Monitor the Android Security Bulletin and CISA’s KEV/BOD 22‑01 pages.
