CVE-2026-97588CVE-2026-97588
Description
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.
