When the socket is closed,\nllc_sap_remove_socket() releases only the socket reference, leaving\nthe SAP on llc_sap_list with sk_count == 0.\n\nThis is user-visible because repeated autobind and close cycles can consume\nall dynamic SAP values and make later autobinds fail with -EUSERS.\n\nDrop the caller's reference after a successful autobind, matching\nllc_ui_bind()'s ownership model.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/21a537606fe35be2b85971a5fd35c0023b6ef98f","https://git.kernel.org/stable/c/61a7ff4a62003b55a15022567486741b3bd83914","https://git.kernel.org/stable/c/660667cd406648bbaffbd5c0d897c2263a852f11","https://git.kernel.org/stable/c/79dc4b508e3f2649390a1f745f7657813e5938ec","https://git.kernel.org/stable/c/a2f9fa31ae021ef1fdcaf3ab17bd49f9223dd6a4"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72022","score":0.0022,"percentile":0.12527,"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).
