Overview
What is CVE-2026-97588?
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.
