Status: ModifiedMedium (6.5)—
Severity6.5Medium · CVSS 3.1
Exploitation probability0.31 %higher than 22% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In DeepCopy of btif_av.cc, there is a possible out of bounds read due to improper casting. This could lead to remote information disclosure over Bluetooth with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-9 Android-10Android ID: A-140768453
