Returning a negative error code causes the crypto engine to\nassume the driver failed to take ownership and triggers a second\ncompletion via crypto_request_complete(), resulting in a double\ncompletion. This pattern occurs in paes_s390.c 4 times and once in\nphmac_s390.c.\n\nFixed in phmac_do_one_request() and all four paes do_one_request\ncallbacks (ecb, cbc, ctr, xts) by returning 0 after explicit\nfinalization instead of propagating the error code.","state":0,"publishedAt":"2026-09-25T10:22:07.441+00:00","modifiedAt":"2026-10-19T09:09:53.14+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\": \"972e0d9b7d1d112240ccde1f1be85bf9ffaa1720\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6cd87cb5ef6ca50ae17c371482ceaab1d635e232\",\n                            \"lessThan\": \"5480291aa848e19e61175abfd457933516db70c6\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"6cd87cb5ef6ca50ae17c371482ceaab1d635e232\",\n                            \"lessThan\": \"ac1481320110b803ab9b79ab4d2ca11a74fc05f2\",\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":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/972e0d9b7d1d112240ccde1f1be85bf9ffaa1720","https://git.kernel.org/stable/c/5480291aa848e19e61175abfd457933516db70c6","https://git.kernel.org/stable/c/ac1481320110b803ab9b79ab4d2ca11a74fc05f2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97589","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97589","identifiers":["CVE-2026-97589"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
