CVE-2026-72226

CVE-2026-72226 concerns the Linux kernel’s batman-adv TT TVLV handling. A unicast TVLV contains the number of VLANs (u16) and multiplies it by 8 (batadv_tvlv_tt_vlan_data). This can overflow the 16-bit tt_vlan_len, invalidating safety checks for out-of-bounds access. The published fix switches to...
