The issue occurs when asynchronous AEAD (Authenticated Encryption with Associated Data) instances are used, causing buffers to be freed while still referenced by backend workers, leading to potential memory corruption. The vulnerability affects functions related to krb5 encryption and decryption that were originally designed for synchronous operation but did not properly handle async AEAD implementations. The fix involves filtering out async AEAD instances at allocation time to prevent this unsafe condition.
