CVE-2019-2104

Status: ModifiedMedium (5.5)—
Severity5.5Medium · CVSS 3.0
Exploitation probability0.16 %higher than 5% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In HIDL, safe_union, and other C++ structs/unions being sent to application processes, there are uninitialized fields. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android-8.0 Android-8.1 Android-9. Android ID: A-131356202
