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.","state":0,"publishedAt":"2026-09-25T10:22:06.796+00:00","modifiedAt":"2026-10-19T09:09:52.16+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"arch/s390/crypto/paes_s390.c\",\n                        \"arch/s390/crypto/phmac_s390.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6cd87cb5ef6ca50ae17c371482ceaab1d635e232\",\n                            \"lessThan\": \"f6b263679aa72ad2e534bf93db55f2589549a40e\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6cd87cb5ef6ca50ae17c371482ceaab1d635e232\",\n                            \"lessThan\": \"e267bd142664a181474112392aeaa8b3d4b12f2e\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6cd87cb5ef6ca50ae17c371482ceaab1d635e232\",\n                            \"lessThan\": \"7a08507ea5b4d06ad8d269287913573f34467565\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"arch/s390/crypto/paes_s390.c\",\n                        \"arch/s390/crypto/phmac_s390.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.53\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.7\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/f6b263679aa72ad2e534bf93db55f2589549a40e","https://git.kernel.org/stable/c/e267bd142664a181474112392aeaa8b3d4b12f2e","https://git.kernel.org/stable/c/7a08507ea5b4d06ad8d269287913573f34467565"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97588","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97588","identifiers":["CVE-2026-97588"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
