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

Description: The issue is related to a permissions bypass in the getMinimalSize function of PipBoundsAlgorithm.java, which could allow for local escalation of privilege without needing additional execution privileges. User interaction is not required for exploitation.

Recommendations: For Android version Android-11, consider restricting the use of the PipBoundsAlgorithm.java function until a patch is available. As a temporary workaround, avoid using the getMinimalSize function in PipBoundsAlgorithm.java to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
