The shared memory buffer used by srcPtr can be freed by another thread because it is not protected by a mutex. Subsequently, a use after free AIGABRT can occur in a race condition. SafetyNet logging is not added to avoid log spamming. The mutex lock is called to setup for decryption, which is called frequently. The crash was reproduced on the device before the fix. Verified the test passes after the fix.
