They live in queue->tx_skb\nwhich gets freed without remorse nor checking.\n\nmacb_free_consistent() gets called in a few codepaths, but only close will\ntrigger the added expressions. In macb_open() and macb_alloc_consistent()\nfailure cases, queues' tx_skb just got allocated and are empty.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0e9797dc4ebdefe1b7f931b1f92d5e98e5dbf655","https://git.kernel.org/stable/c/109241d9880488aafd8e104832b4d4859ad57244","https://git.kernel.org/stable/c/2143fdc0ce27adbb1caaa1a97e0bfb9f3750aef4","https://git.kernel.org/stable/c/26b131b2d5b55a81ef6182769d28105a870c0eb2","https://git.kernel.org/stable/c/27f575836cfebbf872dec020428742b10650a955"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72017","score":0.00211,"percentile":0.11403,"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).
