With nexthop compatibility mode enabled,\na concurrent replacement can grow the group between these independent\nsnapshots.  rt6_fill_node() can then legitimately return -EMSGSIZE, so\nthe warning does not prove a sizing bug.\n\nRemove the warning.  The existing error path still frees the skb and\nreports the error to listeners.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99070","source_modified_at":"2026-10-23T12:23:13.342Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"907eea486888cfe118c19759bbc4b8fca2e004df","lessThan":"8a3b935b6b6037eefb36bd27a60793a008358e8d","status":"affected","versionType":"git"},{"version":"907eea486888cfe118c19759bbc4b8fca2e004df","lessThan":"7b112bd43f1172fb152e848570a957467008a5ae","status":"affected","versionType":"git"},{"version":"907eea486888cfe118c19759bbc4b8fca2e004df","lessThan":"4ac7d92a4698e34e614c254359665b9de1f65283","status":"affected","versionType":"git"},{"version":"907eea486888cfe118c19759bbc4b8fca2e004df","lessThan":"291fe0bafee78c95f9f2e7f579f17793fd5a1e5a","status":"affected","versionType":"git"},{"version":"907eea486888cfe118c19759bbc4b8fca2e004df","lessThan":"c97426ec649d99596d8969e1a052c16b14b7b485","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99070","source_modified_at":"2026-10-23T12:23:13.342Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.12","status":"affected"},{"version":"0","lessThan":"5.12","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.57","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.11","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-2026-99070","source_modified_at":"2026-10-23T12:23:13.342Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"8a3b935b6b6037eefb36bd27a60793a008358e8d","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99070","source_modified_at":"2026-10-23T12:23:13.342Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"7b112bd43f1172fb152e848570a957467008a5ae","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99070","source_modified_at":"2026-10-23T12:23:13.342Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"4ac7d92a4698e34e614c254359665b9de1f65283","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99070","source_modified_at":"2026-10-23T12:23:13.342Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"291fe0bafee78c95f9f2e7f579f17793fd5a1e5a","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-23T12:23:13.342Z","modified_at":"2026-10-23T12:23:13.342Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99070","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:23:13.342Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/8a3b935b6b6037eefb36bd27a60793a008358e8d"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7b112bd43f1172fb152e848570a957467008a5ae"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4ac7d92a4698e34e614c254359665b9de1f65283"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/291fe0bafee78c95f9f2e7f579f17793fd5a1e5a"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c97426ec649d99596d8969e1a052c16b14b7b485"}],"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":"2026-10-23T12:23:13.342Z","content_hash":"48946c829bad2697276d0759f5d870544c47d1f71a2c4c4cc08ca45744c7739a"}}
