The Wear OS Security Bulletin contains details of security vulnerabilities affecting the Wear OS platform. The full Wear OS update comprises the security patch level of 2023-08-05 or later from the August 2023 Android Security Bulletin in addition to all issues in this bulletin.
We encourage all customers to accept these updates to their devices.
Note: Please contact your device supplier for device firmware images.
The most severe of these issues is a high security vulnerability in the Framework component that could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation. The severity assessment is based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are turned off for development purposes or if successfully bypassed.
In the sections below, we provide details for each of the security vulnerabilities that apply to the 2023-08-01 patch level. Vulnerabilities are grouped under the component they affect. Issues are described in the tables below and include CVE ID, associated references, type of vulnerability, severity, and updated AOSP versions (where applicable). When available, we link the public change that addressed the issue to the bug ID, like the AOSP change list. When multiple changes relate to a single bug, additional references are linked to numbers following the bug ID. Devices with Android 10 and later may receive security updates as well as Google Play system updates.
