The crypto API's\ncompletion wrapper treats -EBUSY as a queueing status and swallows it,\npreventing the completion callback from firing. This causes callers\nusing crypto_wait_req() to block indefinitely.\n\nTranslate persistent -EBUSY to -EIO after retry exhaustion to ensure\nproper error propagation and callback invocation.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
