{"apiVersion":"1.0","identifier":"CVE-2026-72417","description":"In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: Validate iph->ihl in nf_flow_ip4_tunnel_proto() Add sanity check for iph->ihl field in nf_flow_ip4_tunnel_proto() before using it to compute the header size, avoiding out-of-bounds access with malformed IP headers. While at it, use iph->protocol instead of the hardcoded IPPROTO_IPIP constant when setting ctx->tun.proto and reference ctx->tun.hdr_size when updating ctx->offset.","publishedAt":"2026-08-15T06:22:15","lastModifiedAt":"2026-08-17T06:19:08","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72417","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00554,"riskScore":1.03,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72417","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72417","en":"https://www.redsauce.net/en/cves/CVE-2026-72417","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72417","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72417","de":"https://www.redsauce.net/de/cves/CVE-2026-72417","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72417","el":"https://www.redsauce.net/el/cves/CVE-2026-72417"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72417"}}
