Android’s monthly security bulletin was released on July 7th. The content of the security information announced this time has been notified to the partner at least one month ago. Updates should be provided by each company in the future. As usual, this month’s security patch consists of two patches, “2021-07-01” and “2021-07-05”, which also includes fixes for vulnerabilities implemented in the past. Please note that devices running Android 10 or later may receive updates to the “Google Play” system in addition to security updates. ■ Security patch levels “2021-07-01” and “2021-07-01” are subsets that omit some time-consuming kernel components and some modifications for specific vendors. It’s deliberately split so that Android partners can quickly provide updates to their users. This month, two vulnerabilities were addressed in the framework, two in the media framework, and 13 in the system. Issues with severity “Critical” are not included, but issues fixed in system components may allow specially crafted local applications to gain additional access without user intervention. That is. “CVE-2021-0441”, “CVE-2021-0601” and “CVE-2021-0590” are also included in the “Google Play” system update (Project Mainline). ■ Security patch levels “2021-07-05” and “2021-07-05” are complete versions that include all vulnerability fixes. In addition to the fixes in 2021-07-01, 1 issue was addressed in the framework, 4 in the system, 1 in the MediaTek component, 1 in Widevine DRM, and 10 in the Qualcomm component. Please note that the Widevine DRM and Qualcomm components also fix the “Critical” severity issue. In addition, Qualcomm’s closed source component has also fixed a number of vulnerabilities, including five “Critical” severity.
