{"id":"CVE-2026-97588","summary":"s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/crypto: Map EBUSY to EIO when key conversion fails repeatedly\n\nWhen hardware persistently returns -EBUSY after exhausting retries,\nthe error propagates to crypto_finalize_*_request(). 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.","modified":"2026-09-26T03:48:40.511934309Z","published":"2026-09-25T10:22:06.796Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97588.json"},"references":[{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7a08507ea5b4d06ad8d269287913573f34467565"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e267bd142664a181474112392aeaa8b3d4b12f2e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f6b263679aa72ad2e534bf93db55f2589549a40e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/97xxx/CVE-2026-97588.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97588"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232"},{"fixed":"f6b263679aa72ad2e534bf93db55f2589549a40e"},{"fixed":"e267bd142664a181474112392aeaa8b3d4b12f2e"},{"fixed":"7a08507ea5b4d06ad8d269287913573f34467565"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97588.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.16.0"},{"fixed":"6.18.53"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-97588.json"}}],"schema_version":"1.9.0"}
