If devlink_alloc() fails and\nwe try to use devlink_priv() on the NULL return, the kernel gets very\nunhappy and panics. With this fix, the driver load will still fail,\nbut at least it won't panic the kernel.","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/0020c16c8af7f4bc9503a2088fb30793b6771fac","https://git.kernel.org/stable/c/0d02efe7f25158c93146e3bb827bc7bb3cd5e71a","https://git.kernel.org/stable/c/4a54903ff68ddb33b6463c94b4eb37fc584ef760","https://git.kernel.org/stable/c/5325f50de5b1433b27dda7ccff5cb7283722a3f1","https://git.kernel.org/stable/c/c177dd465f5c1e5f242cdb9258826c591c257e9a"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:11:26.888974865+00:00"},"epss":{"cve":"CVE-2023-53470","score":0.00159,"percentile":0.05023,"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).
