Multiple vulnerabilities have been discovered in the Google Android operating system (OS), the most severe of which could allow for escalation of privilege. Android is an operating system developed by Google for mobile devices, including, but not limited to, smartphones, tablets, and watches. Successful exploitation of the most severe of these vulnerabilities could allow for escalation of privilege. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.
THREAT INTELLIGENCE: There are currently no reports of these vulnerabilities being exploited in the wild.
SYSTEMS AFFECTED:
- Android OS builds utilizing Security Patch Levels issued prior to February 5, 2022
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

Successful exploitation of the most severe of these vulnerabilities could allow for escalation of privilege. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.
RECOMMENDATIONS:
We recommend the following actions be taken:
- Apply appropriate updates by Google Android or mobile carriers to vulnerable systems, immediately after appropriate testing.
- Remind users to only download applications from trusted vendors in the Play Store.
- Remind users not to visit un-trusted websites or follow links provided by unknown or un-trusted sources.
- Inform and educate users regarding threats posed by hypertext links contained in emails or attachments, especially from un-trusted sources.
