This happens because sdiodev->bus is set 2 times:\nfirst in brcmf_sdio_probe() and second time in brcmf_sdiod_probe(). Fix\nthis by chaning the brcmf_sdio_probe() function to return the error code\nand set sdio->bus only there.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-476"],"references":["https://git.kernel.org/stable/c/243307a0d1b0d01538e202c00454c28b21d4432e","https://git.kernel.org/stable/c/379aac7ee8240848aa35f605b06addb4617c863e","https://git.kernel.org/stable/c/64ccb0aac41c5055780c2a58bbe2c1b362ceccde"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43144","score":0.00126,"percentile":0.02283,"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).
