CVE-2026-23459

In the Linux kernel, the following vulnerability has been resolved: iptunnel: adapt iptunnelxmitstats to NETDEVPCPUSTATDSTATS Blamed commits forgot that vxlan/geneve use udptunnel6xmitskb which call iptunnelxmitstats. iptunnelxmitstats was assuming tunnels were only using NETDEVPCPUSTATTSTATS...

CVE-2026-23459

The CVE-2026-23459 issue affects the Linux kernel IP tunnel code, specifically iptunnel_xmit_stats(). The bug arose because the function assumed tunnels used NETDEV_PCPU_STAT_TSTATS, while vxlan/geneve tunnels call udp_tunnel[6]_xmit_skb() and read NETDEV_PCPU_STAT_DSTATS, creating potential data...
