MS-ISAC CYBERSECURITY ADVISORY
MS-ISAC ADVISORY NUMBER:
2025-047
DATE(S) ISSUED:
05/05/2025
SUBJECT:
Multiple Vulnerabilities in Google Android OS Could Allow for Remote Code Execution
OVERVIEW:
Multiple vulnerabilities have been discovered in Google Android OS, the most severe of which could allow for remote code execution with no additional execution privileges needed. Android is an operating system developed by Google for mobile devices, such as smartphones, tablets, and watches. Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution within the context of the affected service account. Depending on the privileges associated with the service account, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Service accounts that are configured to have fewer user rights on the system could be less impacted than those that operate with administrative user rights.
THREAT INTELLIGENCE:
Google reports that CVE-2025-27363 is reportedly under limited, targeted exploitation.
SYSTEMS AFFECTED:
- Android OS security patch levels issued prior to May 5, 2025.
RISK:
Government:
- Large and medium government entities: High
- Small government entities: High
Businesses:
- Large and medium business entities: High
- Small business entities: High
Home users: Low
TECHNICAL SUMMARY:

- Multiple vulnerabilities in Imagination Technologies. (CVE-2024-12577, CVE-2024-46974, CVE-2024-46975, CVE-2024-47891, CVE-2024-47896, CVE-2024-47900, CVE-2024-52939)
- A vulnerability in MediaTek components. (CVE-2025-20666)
- Multiple vulnerabilities in Qualcomm components. (CVE-2024-45580, CVE-2025-21453, CVE-2025-21459, CVE-2025-21467, CVE-2025-21468)
- Multiple vulnerabilities in Qualcomm closed-source components. (CVE-2024-49835, CVE-2024-49841, CVE-2024-49842, CVE-2024-49845, CVE-2024-49846, CVE-2024-49847)
RECOMMENDATIONS:
We recommend the following actions be taken:
- Apply appropriate mitigations provided by Google to vulnerable systems immediately after appropriate testing. (M1051: Update Software)
- Safeguard 7.1: Establish and Maintain a Vulnerability Management Process: Establish and maintain a documented vulnerability management process for enterprise assets. Review and update documentation annually, or when significant enterprise changes occur that could impact this Safeguard.
- Safeguard 7.4: Perform Automated Application Patch Management: Perform application updates on enterprise assets through automated patch management on a monthly, or more frequent, basis.
- Safeguard 7.5: Perform Automated Vulnerability Scans of Internal Enterprise Assets: Perform automated vulnerability scans of internal enterprise assets on a quarterly, or more frequent, basis. Conduct both authenticated and unauthenticated scans, using a SCAP-compliant vulnerability scanning tool.
- Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring. (M1050: Exploit Protection)
- Safeguard 10.5: Enable Anti-Exploitation Features: Enable anti-exploitation features on enterprise assets and software, where possible, such as Apple® System Integrity Protection (SIP) and Gatekeeper™.
- Safeguard 13.10: Perform Application Layer Filtering: Perform application layer filtering. Example implementations include a filtering proxy, application layer firewall, or gateway.
- Restrict execution of code to a virtual environment on or in transit to an endpoint system. (M1048: Application Isolation and Sandboxing)
- Safeguard 16.8: Separate Production and Non-Production Systems: Maintain separate environments for production and non-production systems.
