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

Description A permission bypass issue exists in the getAvailabilityStatus of several Transcode Permission Controllers due to a missing permission check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not required for exploitation.

Recommendations For Android versions prior to the fixed version, consider restricting access to the Transcode Permission Controllers until a patch is available. As a temporary workaround, disabling the affected controllers may help minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
