CVE-2026-97965

The Linux kernel contains a vulnerability in the vxlan component where a packet transmitted through a device configured with VXLAN_F_COLLECT_METADATA and VXLAN_F_GBP can cause information leakage. If the external ip_tunnel_info lacks the IP_TUNNEL_VXLAN_OPT_BIT flag, the md pointer remains pointi...
