Control\nthen falls through to the common error label, which frees the same\nskb a second time and counts it again.\n\nReturn right after clearing the fragments when the skb owns frags;\nthe no-frag case still drops through and frees the head skb once.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":[],"references":["https://git.kernel.org/stable/c/4f09172aff5f73a5e914f4fbc0d00a1c2ea9f7cb","https://git.kernel.org/stable/c/6fb7b769d6ed6d1d2e02af4a80e57a2477f35086","https://git.kernel.org/stable/c/db986098f30881fafcc752800aa3b13fd289c922","https://git.kernel.org/stable/c/de691dc3227b061c4d0beba9f0128fe1ff33dd68"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-74545","score":0.00671,"percentile":0.52051,"date":"2026-10-31"},"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).
