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.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/489114c9ecae44e523361a4b3e610ee5ebd9189c","https://git.kernel.org/stable/c/961563117626f4681623077ec0cfd86f86da0d49","https://git.kernel.org/stable/c/f34b1bcac4581a5bd3daf9eff90f175e736b54aa"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-99026","score":0.00174,"percentile":0.06823,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
