A double free issue was addressed with improved memory management. This issue is fixed in iOS 13.5 and iPadOS 13.5, macOS Catalina 10.15.5. A remote attacker may be able to cause unexpected system termination or corrupt kernel memory.
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
