CVE-2023-21306

Name of the Vulnerable Software and Affected Versions Android versions prior to the fixed version

Description In ContentService, there is a possible way to read installed sync content providers due to side channel information disclosure. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the ContentService until a patch is available. As a temporary workaround, avoid using sensitive information with the installed sync content providers until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
