CVE-2026-97588 is fixed in linux on 1 platform by DEBIAN-CVE-2026-97588 (version 7.2.7-1), released October 2, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
