Name of the Vulnerable Software and Affected Versions: Android versions 8.1 through 11

Description: The issue is related to a possible out of bounds read due to an integer overflow in the decrypt 1 2 function of CryptoPlugin.cpp. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.

Recommendations: For Android versions 8.1 through 11, consider restricting access to sensitive information until a patch is available. As a temporary workaround, consider disabling the decrypt 1 2 function in CryptoPlugin.cpp to minimize the risk of exploitation.
