Multiple vulnerabilities have been discovered in the Google Android operating system(OS) and Pixel, the most severe of which could allow for remote code execution. Google Android is an operating system developed by Google for mobile devices, including, but not limited to, smartphones, tablets, and watches. Google Pixel is a brand of consumer electronic devices developed by Google that run either Chrome OS or the Android operating system. Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution within the context of a privileged process. 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.

TECHNICAL SUMMARY:
Multiple vulnerabilities have been discovered in Google Android OS and Pixel, the most severe of which could allow for remote code execution within the context of a privileged process. Details of these vulnerabilities are as follows:

•   A vulnerability in Android runtime could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. (CVE-2021-39689)
•   Multiple vulnerabilities in Framework, the most severe of which could lead to local escalation of privilege with User execution privileges needed. User interaction is needed for exploitation.(CVE-2021-39692, CVE-2021-39693, CVE-2021-39695, CVE-2021-39697, CVE-2021-39624,CVE-2021-39690, CVE-2021-39694)
•   A vulnerability in Media Framework could lead to remote information disclosure with no additional execution privileges needed. User interaction is needed for exploitation.(CVE-2021-39667)
•   Multiple vulnerabilities in System, the most severe of which could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2021-39708, CVE-2021-0957, CVE-2021-39701, CVE-2021-39702,CVE-2021-39703, CVE-2021-39704, CVE-2021-39706, CVE-2021-39707, CVE-2021-39709,CVE-2021-39705)
•   Vulnerabilities exist in the Media Codecs and Permission controller components of Project Mainline, the most severe of which could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.(CVE-2021-39667, CVE-2021-39694)
•   A vulnerability in Android Runtime that could enable a local attacker to bypass memory restrictions in order to gain access to additional permissions. (CVE-2021-0959)
•   Multiple vulnerabilities in Android Kernel components, the most severe of which could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. (CVE-2020-29368, CVE-2021-39685, CVE-2021-39686,CVE-2021-39698, CVE-2021-3655)
•   Multiple high severity vulnerabilities in MediaTek video decoder and ims service components. (CVE-2022-20047, CVE-2022-20048,CVE-2022-20053)
•   Multiple high severity vulnerabilities in Android Qualcomm WLAN and Display components. (CVE-2021-35088,CVE-2021-35103, CVE-2021-35105, CVE-2021-35106, CVE-2021-35117)
•   Multiple high and critical severity vulnerabilities in Android Qualcomm closed-source components. (CVE-2021-1942, CVE-2021-35110,CVE-2021-1950, CVE-2021-30328, CVE-2021-30329, CVE-2021-30332, CVE-2021-30333)
•   Multiple moderate severity vulnerabilities in Pixel Kernel components. (CVE-2021-43267, CVE-2021-37159,CVE-2021-39712, CVE-2021-39713, CVE-2021-39714, CVE-2021-41864, CVE-2022-20003,CVE-2021-21781, CVE-2021-33624, CVE-2021-39711, CVE-2021-39715, CVE-2021-39792,CVE-2021-43975)
•   Multiple critical, high and moderate severity vulnerabilities in Pixel Modem, Telephony, Display/Graphics, Titan M2, Camera, Kernel, Titan M, Audio and Bootloader components. (CVE-2021-39720,CVE-2021-39723, CVE-2021-39737, CVE-2021-25279, CVE-2021-25478, CVE-2021-25479,CVE-2021-39710, CVE-2021-39734, CVE-2021-39793, CVE-2021-39726, CVE-2021-39727,CVE-2021-39718, CVE-2021-39719, CVE-2021-39721, CVE-2021-39725, CVE-2021-39729,CVE-2021-39731, CVE-2021-39732, CVE-2021-39733, CVE-2021-39735, CVE-2021-39736,CVE-2021-39716, CVE-2021-39717, CVE-2021-39722, CVE-2021-39724, CVE-2021-39730)
•   A moderate severity vulnerability in a Pixel Qualcomm Audio component. (CVE-2021-30299)
•   A moderate severity vulnerability in a Pixel Qualcomm closed-course component. (CVE-2021-30331)

Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution within the context of a privileged process. 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 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.
