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

Description The issue is related to improper casting in the SurfaceFlinger::createLayer function of SurfaceFlinger.cpp. This could lead to arbitrary code execution, resulting in local escalation of privilege without requiring additional execution privileges. User interaction is not necessary for exploitation.

Recommendations For Android versions prior to the fixed version, update to a version that includes the fix for this issue to prevent local escalation of privilege. As a temporary workaround, consider restricting access to the SurfaceFlinger module to minimize the risk of exploitation.
