          Hardware: iPhone / iPad
                OS: iOS 13
            Status: NEW
          Severity: Normal

Version: iOS 13.3 (17C5032d) / developer beta 1

Safari crashes ~85% of the time when creating a new credential or authenticating with USB security keys (I tested over USB-C on iPad Pro with various Yubikeys and many other devices).

Full debug details are in FB7428936.


Detected over-release of a CFTypeRef
