The clone is used immediately to set cloned->len, so\nan skb_clone() failure results in a NULL pointer dereference.\n\nCheck the clone before using it. If previous fragments were already\nqueued, preserve the driver's existing partial-write behavior by\nreturning the number of bytes submitted so far.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/05f789fa90d95d5771230e78453cedff2486039d","https://git.kernel.org/stable/c/112490467586146d323cb7230b1d72137e36900c","https://git.kernel.org/stable/c/4c1b25d85f4c9a0f85f3f8c39988ad266a3f3095","https://git.kernel.org/stable/c/7edd4db82f9429591de10be4c904c817f12ba029","https://git.kernel.org/stable/c/f7aebaee2961bfcb86f282202d3dbd9b69db1a7c"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-74263","score":0.00209,"percentile":0.11055,"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).
