  "description": "In the Linux kernel, the following vulnerability has been resolved:  crypto: krb5enc - fix async decrypt skipping hash verification  krb5enc_dispatch_decrypt() sets req-\u003Ebase.complete as the skcipher callback, which is the caller\u0027s own completion handler. When the skcipher completes asynchronously, this signals \u0022done\u0022 to the caller without executing krb5enc_dispatch_decrypt_hash(), completely bypassing the integrity verification (hash check).  Compare with the encrypt path which correctly uses krb5enc_encrypt_done as an intermediate callback to chain into the hash computation on async completion.  Fix by adding krb5enc_decrypt_done as an intermediate callback that chains into krb5enc_dispatch_decrypt_hash() upon async skcipher completion, matching the encrypt path\u0027s callback pattern.  Also fix EBUSY/EINPROGRESS handling throughout: remove krb5enc_request_complete() which incorrectly swallowed EINPROGRESS notifications that must be passed up to callers waiting on backlogged requests, and add missing EBUSY checks in krb5enc_encrypt_ahash_done for the dispatch_encrypt return value.   Unset MAY_BACKLOG on the async completion path so the user won\u0027t see back-to-back EINPROGRESS notifications.",
