{"apiVersion":"1.0","identifier":"CVE-2026-72226","description":"In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: prevent TVLV OOB check overflow A TT unicast TVLV contains the number of VLANs stored in it. This number is an u16 and gets multiplied by the size of the struct batadv_tvlv_tt_vlan_data (8 bytes). The size can therefore overflow the u16 used to store the tt_vlan_len. All additional safety checks to prevent out-of-bounds access of the TVLV buffer are invalid due to this overflow. Using size_t prevents this overflow and ensures that the safety checks compare against the actual buffer requirements.","publishedAt":"2026-08-15T06:21:49","lastModifiedAt":"2026-08-17T06:18:23","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72226","cvssScore":9.8,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00704,"riskScore":1.04,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72226","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72226","en":"https://www.redsauce.net/en/cves/CVE-2026-72226","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72226","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72226","de":"https://www.redsauce.net/de/cves/CVE-2026-72226","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72226","el":"https://www.redsauce.net/el/cves/CVE-2026-72226"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72226"}}
