Name of the Vulnerable Software and Affected Versions Android versions Android-13

Description The issue is related to a permissions bypass in the AndroidManifest.xml file, which could allow granting signature permissions. This might lead to a local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

As a temporary workaround, review and limit the use of permissions defined in the AndroidManifest.xml file to minimize the risk of exploitation.
