{"schema":"threatline.record/2","record":{"id":"CVE-2026-98452","aliases":[],"summary":"smb: client: clean up failed cached directory opens","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: client: clean up failed cached directory opens\n\nopen_cached_dir() sends CREATE and QUERY_INFO as a compound request. If\nthe CREATE succeeds but a later command returns an error, the function\nmust retain the CREATE FID so common cleanup can issue SMB2_close(). It\nalso must not treat a response error as a valid CREATE.\n\nValidate the CREATE response before using its fields, record the FIDs, and\nmark the handle open before handling errors from later compound commands.\nMove the -EREMCHG reconnect handling before response validation so a\nmissing response does not hide the reconnect request. Count the handle\nwhen it is marked open; confirmed close responses decrement the counter,\nwhile existing close retry behavior remains best effort on transport\nfailures.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98452","source_modified_at":"2026-10-19T09:19:47.547Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"b0f6df737a1c5d9d5ff90cc946205d8af46cc067","lessThan":"48958ddda3d7eee3600261e2d90671f63e055dc4","status":"affected","versionType":"git"},{"version":"b0f6df737a1c5d9d5ff90cc946205d8af46cc067","lessThan":"abab661eed00fa102d3c35ddf1cce4f687e718c1","status":"affected","versionType":"git"},{"version":"b0f6df737a1c5d9d5ff90cc946205d8af46cc067","lessThan":"7c1509598a4fdfb54cb09ce33e4405bd6dbd8295","status":"affected","versionType":"git"},{"version":"b0f6df737a1c5d9d5ff90cc946205d8af46cc067","lessThan":"d2ff5fb93ea83034025850266b5eed391f96b825","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98452","source_modified_at":"2026-10-19T09:19:47.547Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.1","status":"affected"},{"version":"0","lessThan":"5.1","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.55","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.9","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-2026-98452","source_modified_at":"2026-10-19T09:19:47.547Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"48958ddda3d7eee3600261e2d90671f63e055dc4","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98452","source_modified_at":"2026-10-19T09:19:47.547Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"7c1509598a4fdfb54cb09ce33e4405bd6dbd8295","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00175,"percentile":0.06674,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:15:02.436Z","modified_at":"2026-10-19T09:19:47.547Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98452","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:19:47.547Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98452","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/48958ddda3d7eee3600261e2d90671f63e055dc4"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/abab661eed00fa102d3c35ddf1cce4f687e718c1"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7c1509598a4fdfb54cb09ce33e4405bd6dbd8295"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/d2ff5fb93ea83034025850266b5eed391f96b825"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:19:47.547Z","content_hash":"2c362c4564ceb42cf707b5637114c090cf9aa19e7547641c79441f6c37855cd6"}}
