{"schema":"threatline.record/2","record":{"id":"CVE-2026-97589","aliases":[],"summary":"s390/crypto: Fix wrong return code to engine in asynch callbacks","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ns390/crypto: Fix wrong return code to engine in asynch callbacks\n\nWhen crypto_finalize_hash_request() or\ncrypto_finalize_skcipher_request() explicitly completes a request, the\ndo_one_request callback must return 0 to indicate successful\nhandling. 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.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97589","source_modified_at":"2026-10-19T09:09:53.140Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232","lessThan":"972e0d9b7d1d112240ccde1f1be85bf9ffaa1720","status":"affected","versionType":"git"},{"version":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232","lessThan":"5480291aa848e19e61175abfd457933516db70c6","status":"affected","versionType":"git"},{"version":"6cd87cb5ef6ca50ae17c371482ceaab1d635e232","lessThan":"ac1481320110b803ab9b79ab4d2ca11a74fc05f2","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97589","source_modified_at":"2026-10-19T09:09:53.140Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.16","status":"affected"},{"version":"0","lessThan":"6.16","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97589","source_modified_at":"2026-10-19T09:09:53.140Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"972e0d9b7d1d112240ccde1f1be85bf9ffaa1720","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97589","source_modified_at":"2026-10-19T09:09:53.140Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"5480291aa848e19e61175abfd457933516db70c6","basis":"first unaffected version stated in the CVE record"}],"cvss":7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00143,"percentile":0.0327,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:22:07.441Z","modified_at":"2026-10-19T09:09:53.140Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97589","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:09:53.140Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97589","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/972e0d9b7d1d112240ccde1f1be85bf9ffaa1720"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/5480291aa848e19e61175abfd457933516db70c6"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/ac1481320110b803ab9b79ab4d2ca11a74fc05f2"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:09:53.140Z","content_hash":"32d7449a130554abac619e138d82e6009c468b2b0ae2dd026e222815d3b4691f"}}
