The caller retains ownership of the\nbuffer, and the preceding netdev patch frees the skb when enqueue\nreturns this permanent error.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":[],"references":["https://git.kernel.org/stable/c/4890152a3069f5cb58cc24b08cfd5fe95e568fa1","https://git.kernel.org/stable/c/668aa3238548584ca9772da9cf43ae8c2389bbf1","https://git.kernel.org/stable/c/6b6bbc6c878d64eacc60877df49fce7b1b6a08d0","https://git.kernel.org/stable/c/75a604e9f1cfdebda421062fdf42225ca32154cd","https://git.kernel.org/stable/c/9b0fa8a9e1057614a533cc3f18b17f82aab028d8"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-80987","score":0.00501,"percentile":0.42627,"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).
