CVE-2026-97591
In the Linux kernel, the following vulnerability has been resolved:

s390/crypto: Fix handling of EBUSY in PHMAC when req is pushed to crypto engine

When a request is transferred to the engine via
crypto_transfer_hash_request_to_engine() there are two return codes
signaling a successful transfer: EINPROGRESS and EBUSY. However the
correct handling of EBUSY was missing and has been added as a return
code indicating a successful transfer to the crypto engine.
