{"apiVersion":"1.0","identifier":"CVE-2026-72229","description":"In the Linux kernel, the following vulnerability has been resolved: batman-adv: clean untagged VLAN on netdev registration failure When an mesh interface is registered, it creates an untagged struct batadv_meshif_vlan on top of it via the NETDEV_REGISTER notifier. But in this process, another receiver of this notification can veto the registration. The netdev registration will be aborted because of this veto. The register_netdevice() call will try to clean up the net_device using unregister_netdevice_queue() - which only uses the .priv_destructor to free private resources. In this situation, .dellink will not be called. The cleanup of the untagged batadv_meshif_vlan must thefore be done in the destructor to avoid a leak of this object.","publishedAt":"2026-08-15T06:21:49","lastModifiedAt":"2026-08-17T06:18:24","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72229","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00211,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72229","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72229","en":"https://www.redsauce.net/en/cves/CVE-2026-72229","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72229","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72229","de":"https://www.redsauce.net/de/cves/CVE-2026-72229","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72229","el":"https://www.redsauce.net/el/cves/CVE-2026-72229"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72229"}}
