CVE-2026-72248
In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: support IPIP tunnel with direct xmit The combination of IPIP tunnel with direct xmit, eg. bridge device, breaks because no dstentry is provided to check the skb headroom and to set the iph-fragoff field. Thi...
UBUNTU-CVE-2026-72053
In the Linux kernel, the following vulnerability has been resolved: net: ipip: require CAPNETADMIN in the device netns for changelink ipipchangelink operates on at most two netns, devnetdev and the tunnel link netns t-net. They differ once the device is created in or moved to a netns other than t...

CVE-2026-72417
The CVE-2026-72417 entry concerns the Linux kernel netfilter flowtable path, specifically nf_flow_ip4_tunnel_proto(). The vulnerability arises from processing IPv4 headers without validating iph->ihl, risking out-of-bounds access when headers are malformed. The fix adds a sanity check on iph-&...
CVE-2026-72249
The CVE-2026-72249 entry documents a Linux kernel netfilter flowtable bug: when pushing IPIP headers, the code uses the wrong direction’s route to calculate headroom, causing iph->frag_off and headroom handling to be incorrect. The issue arises from accessing the other tuple to set IP source/d...

CVE-2026-72248
The CVE-2026-72248 entry pertains to the Linux kernel netfilter flowtable: IPIP tunnels with direct xmit can crash the tunnel transmit path due to missing dst_entry when checking headroom and setting iph->frag_off. The workaround/patch moves dst_cache and dst_cookie out of the runtime union so...
