CVE-2026-23276

CVE-2026-23276 fixes a recursion vulnerability in the Linux kernel networking stack. When a bonded interface in broadcast mode has GRE tunnel slaves, multicast/broadcast traffic could trigger infinite recursion between bond_xmit_broadcast() and ip_tunnel_xmit()/ip6_tnl_xmit(), risking a kernel st...
