EUVD-2026-38938

In the Linux kernel, the following vulnerability has been resolved: sctp: disable BH before calling udptunnelxmitskb udptunnelxmitskb / udptunnel6xmitskb are expected to run with BH disabled. After commit 6f1a9140ecda "add xmit recursion limit to tunnel xmit functions", on the path:...

CVE-2026-53070

CVE-2026-53070 affects the Linux kernel SCTP over UDP. The issue arises because bh (bottom half) handling must stay disabled when calling udp_tunnel_xmit_skb()/udp_tunnel6_xmit_skb(); after the 6f1a9140 patch, the context can move between CPUs, breaking dev_xmit_recursion_inc()/dec() balance and ...

CVE-2026-23459

A flaw was found in the Linux kernel's IP tunnel iptunnel functionality. Incorrect handling of tunnel statistics, specifically within the iptunnelxmitstats function, could lead to a mismatch in how data is processed. On 32-bit kernel systems, this issue may result in data corruption or system...

CVE-2026-23276

A flaw was found in the Linux kernel. When a bond device in broadcast mode has Generic Routing Encapsulation GRE tap interfaces configured as slaves, and these GRE tunnels are routed back through the bond, multicast or broadcast network traffic can trigger an infinite recursion. This recursion...

CVE-2026-23277

CVE-2026-23277 (TEQL NULL pointer dereference in iptunnel_xmit) is fixed in Linux kernel TEQL transmit path. When a GRE Gretap tunnel is TEQL slave, teql_master_xmit() transmits via netdev_start_xmit() without updating skb->dev to the slave. iptunnel_xmit then uses the original dev from skb-&g...
