{"apiVersion":"1.0","identifier":"CVE-2026-72351","description":"In the Linux kernel, the following vulnerability has been resolved: gue: validate REMCSUM private option length GUE private flags can indicate that remote checksum offload metadata is present. The private flags field itself is accounted for by guehdr_flags_len(), but guehdr_priv_flags_len() currently returns 0 even when GUE_PFLAG_REMCSUM is set. This lets a packet with only the private flags field pass validate_gue_flags(), after which gue_remcsum() and gue_gro_remcsum() read the missing REMCSUM start/offset fields from the following bytes. Account for GUE_PLEN_REMCSUM when GUE_PFLAG_REMCSUM is present so that malformed packets are rejected during option validation.","publishedAt":"2026-08-15T06:22:08","lastModifiedAt":"2026-08-17T06:18:39","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72351","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00745,"riskScore":1.05,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72351","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72351","en":"https://www.redsauce.net/en/cves/CVE-2026-72351","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72351","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72351","de":"https://www.redsauce.net/de/cves/CVE-2026-72351","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72351","el":"https://www.redsauce.net/el/cves/CVE-2026-72351"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72351"}}
