Name of the Vulnerable Software and Affected Versions Android versions Android-11

Description The issue is related to a possible location permission bypass due to a missing permission check in the broadcastWifiCredentialChanged function of ClientModeImpl.java. This could lead to local information disclosure of the WiFi network name, requiring System execution privileges. No user interaction is needed for exploitation.

Recommendations For Android version Android-11, consider restricting access to sensitive WiFi network information until a patch is available. As a temporary workaround, review and enforce strict location permission checks to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
