The\nempty-iterator check can do the same.\n\nFor synchronous writes, netfs_unbuffered_write_iter_locked() may then\nreturn an unrelated error instead of wreq->error. This is reachable\nthrough CIFS if cifs_prepare_write() fails to reopen the file or obtain\ncredits.\n\nInitialize ret to 0 so the caller returns wreq->error if no data was\nwritten, or the number of bytes already written otherwise.\n\nFound with Clang's -Wconditional-uninitialized.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97610","source_modified_at":"2026-10-19T09:10:14.001Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"72d08d2839649d1c5efbe375751f4473fa4486af","lessThan":"3d038eebdbd400c3bc4b66bd8aa0dff0c2bcce26","status":"affected","versionType":"git"},{"version":"a0b4c7a49137ed21279f354eb59f49ddae8dffc2","lessThan":"2e38d500471d097cda87d7d374bbc1b13493075d","status":"affected","versionType":"git"},{"version":"a0b4c7a49137ed21279f354eb59f49ddae8dffc2","lessThan":"f18e8774f4d3137fa0a5fb8ffa83d59a719666d8","status":"affected","versionType":"git"},{"version":"0c29f6d63122a0168d67cb8ecde5b4cf7fe4acb0","status":"affected","versionType":"git"},{"version":"6.18.17","lessThan":"6.18.53","status":"affected","versionType":"semver"},{"version":"6.19.7","lessThan":"6.20","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97610","source_modified_at":"2026-10-19T09:10:14.001Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"7.0","status":"affected"},{"version":"0","lessThan":"7.0","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-2026-97610","source_modified_at":"2026-10-19T09:10:14.001Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"3d038eebdbd400c3bc4b66bd8aa0dff0c2bcce26","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97610","source_modified_at":"2026-10-19T09:10:14.001Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"2e38d500471d097cda87d7d374bbc1b13493075d","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97610","source_modified_at":"2026-10-19T09:10:14.001Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.18.53","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-97610","source_modified_at":"2026-10-19T09:10:14.001Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"6.20","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00198,"percentile":0.09048,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:22:20.228Z","modified_at":"2026-10-19T09:10:14.001Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-97610","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:10:14.001Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-97610","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/3d038eebdbd400c3bc4b66bd8aa0dff0c2bcce26"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/2e38d500471d097cda87d7d374bbc1b13493075d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f18e8774f4d3137fa0a5fb8ffa83d59a719666d8"}],"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":"2026-10-19T09:10:14.001Z","content_hash":"2f1f35f8b447e6561e39eceb041eebce9e28a8f81310c8b644b12b055b05d38b"}}
