In this case, udp_tunnel_nic_register()\nreturning an error is just a failed operation, not a kernel bug.\n\nudp_tunnel_nic_register() can fail due to a memory allocation\nfailure (kzalloc() or udp_tunnel_nic_alloc()).\nThis is a normal runtime error and not a kernel bug.\n\nReplace netdev_WARN() with netdev_warn() accordingly.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/087f1ed450dc6e7e49ffbbbe5b78be1218c6d5e0","https://git.kernel.org/stable/c/3c3b148bf8384c8a787753cf20abde1c5731f97f","https://git.kernel.org/stable/c/45e4e4a8772fa1c5f6f38e82b732b3a9d8137af4","https://git.kernel.org/stable/c/51b3033088f0420b19027e3d54cd989b6ebd987e","https://git.kernel.org/stable/c/7758ec35ff3e9a31558eda4f0f9eb0ddfa78a8ba"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:17:07.138532058+00:00"},"epss":{"cve":"CVE-2025-68191","score":0.00205,"percentile":0.10371,"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).
