{"apiVersion":"1.0","identifier":"CVE-2026-72450","description":"In the Linux kernel, the following vulnerability has been resolved: xfrm: validate selector family and prefixlen during match syzbot reported a shift-out-of-bounds in xfrm_selector_match() due to AF_UNSPEC selector with large prefixlen (e.g. 128) matched against IPv4 flow (when XFRM_STATE_AF_UNSPEC is set). Fix this by: - Rejecting mismatched families in xfrm_selector_match. - Returning false in addr4_match if prefixlen > 32. - Returning false in addr_match if prefixlen > 128 (prevents overflow).","publishedAt":"2026-08-15T06:22:18","lastModifiedAt":"2026-08-17T06:19:12","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72450","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00169,"riskScore":0.79,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72450","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72450","en":"https://www.redsauce.net/en/cves/CVE-2026-72450","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72450","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72450","de":"https://www.redsauce.net/de/cves/CVE-2026-72450","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72450","el":"https://www.redsauce.net/el/cves/CVE-2026-72450"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72450"}}
