{"schema":"threatline.record/2","record":{"id":"CVE-2026-99026","aliases":[],"summary":"net: team: free skb when broadcast has no txable port","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: team: free skb when broadcast has no txable port\n\nbc_transmit() sends the original skb through the last txable port.\nWhen no port is txable, it returns false without consuming the skb, but\nteam_xmit() still returns NETDEV_TX_OK. AF_PACKET sends then retain the\nskb and its socket write-memory charge.\n\nA TX-enabled, link-down port keeps the broadcast transmit op installed.\nCarrier can stay up through a second link-up, TX-disabled port or be\nforced on by userspace. Free the original skb on the no-port path while\nleaving the existing drop accounting intact.\n\nDiscovered by Sashiko during review of previous commit.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99026","source_modified_at":"2026-10-23T12:21:13.509Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","lessThan":"961563117626f4681623077ec0cfd86f86da0d49","status":"affected","versionType":"git"},{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","lessThan":"f34b1bcac4581a5bd3daf9eff90f175e736b54aa","status":"affected","versionType":"git"},{"version":"5fc889911a99043a97da1daa0d010ad72cbc3042","lessThan":"489114c9ecae44e523361a4b3e610ee5ebd9189c","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99026","source_modified_at":"2026-10-23T12:21:13.509Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"Linux","vendor":"Linux","versions":[{"version":"3.6","status":"affected"},{"version":"0","lessThan":"3.6","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-2026-99026","source_modified_at":"2026-10-23T12:21:13.509Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"961563117626f4681623077ec0cfd86f86da0d49","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99026","source_modified_at":"2026-10-23T12:21:13.509Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"Linux","ecosystem":null},"version":"489114c9ecae44e523361a4b3e610ee5ebd9189c","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":"2026-10-23T12:21:13.509Z","modified_at":"2026-10-23T12:21:13.509Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99026","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T12:21:13.509Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/961563117626f4681623077ec0cfd86f86da0d49"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f34b1bcac4581a5bd3daf9eff90f175e736b54aa"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/489114c9ecae44e523361a4b3e610ee5ebd9189c"}],"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":"2026-10-23T12:21:13.509Z","content_hash":"69e885c6cf75e5ecb3a8307cdf7caba7076b7f543a01afae62bb54f2fb1a78d4"}}
