If either of those later steps fails, the\nprobe function returns without unregistering the TCPCI port. The explicit\nunregister currently only happens from the remove callback.\n\nRegister a devres action immediately after tcpci_register_port() succeeds,\nso tcpci_unregister_port() runs on later probe failures and on driver\ndetach. Drop the remove callback to avoid unregistering the same port\ntwice.\n\nThis issue was identified during our ongoing static-analysis research while\nreviewing kernel code.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/569f18a83eed0b0be4615f0c7bed40fb5c50e2e6","https://git.kernel.org/stable/c/94b1abf1af94aa5a355e9f03675e07bccfc41c4b","https://git.kernel.org/stable/c/ce2e36e8759dfbfe546723810c306f42f484866d","https://git.kernel.org/stable/c/e5406c8fb71cd2f89a46300a746f6e7972e621e8","https://git.kernel.org/stable/c/e8da46d99d3710106e7c44db14566bf9b57386b5"],"products":[],"source":"nvd","synced_at":"2026-10-21T03:56:58.798400159+00:00"},"epss":{"cve":"CVE-2026-64463","score":0.00138,"percentile":0.03198,"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).
