The previously registered net_devices are then freed by\nmtk_free_dev() while still in NETREG_REGISTERED state, hitting the\nBUG_ON(dev->reg_state != NETREG_UNREGISTERED).\n\nRoute the register_netdev() failure to err_unreg_netdev so the net_devices\nregistered so far are properly unregistered before being freed.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/0fdb944d4df02223c67d5e65c4c134ecb57a5668","https://git.kernel.org/stable/c/245bea0c7ab278150c70366bdeb69b901327133c","https://git.kernel.org/stable/c/310d1ac61a4d5a2ca8356a3a48d263acf54503ce","https://git.kernel.org/stable/c/7254b702e556158e34b4d7c168b5d8e7da5978af","https://git.kernel.org/stable/c/ab3bde3b3e56331b4f53a1f6cf4e5e9d1c14c1a0"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98620","score":0.002,"percentile":0.09714,"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).
