Status: ModifiedCritical (9.8)—
Severity9.8Critical · CVSS 3.1
Exploitation probability0.64 %higher than 50% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In readCString of Parcel.cpp, there is a possible out of bounds write due to an integer overflow. This could lead to arbitrary code execution if IntSan were not enabled, which it is by default. No additional execution privileges are required. User interaction is not needed for exploitation. Product: Android Versions: Android-10 Android ID: A-131859347
