{"apiVersion":"1.0","identifier":"CVE-2026-72136","description":"In the Linux kernel, the following vulnerability has been resolved: xfrm: xfrm_interface: require CAP_NET_ADMIN in the device netns for changelink xfrmi_changelink() operates on at most two netns, dev_net(dev) and the interface link netns xi->net. They differ once the device is created in or moved to a netns other than the one the request runs in. The rtnl changelink path checks CAP_NET_ADMIN only against dev_net(dev), so a caller privileged there but not in xi->net can rewrite an interface that lives in xi->net. Gate xfrmi_changelink() on rtnl_dev_link_net_capable() at its top, before any attribute is parsed.","publishedAt":"2026-08-15T06:21:31","lastModifiedAt":"2026-08-17T06:18:13","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72136","cvssScore":8.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","epssProbability":0.00169,"riskScore":0.89,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72136","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72136","en":"https://www.redsauce.net/en/cves/CVE-2026-72136","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72136","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72136","de":"https://www.redsauce.net/de/cves/CVE-2026-72136","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72136","el":"https://www.redsauce.net/el/cves/CVE-2026-72136"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72136"}}
