In the Linux kernel, the following vulnerability has been resolved:

s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly

When hardware persistently returns -EBUSY after exhausting retries,
the error propagates to crypto_finalize_*_request(). The crypto API's
completion wrapper treats -EBUSY as a queueing status and swallows it,
preventing the completion callback from firing. This causes callers
using crypto_wait_req() to block indefinitely.

Translate persistent -EBUSY to -EIO after retry exhaustion to ensure
proper error propagation and callback invocation.
