headroom\n\nSashiko points out that after stripping the outer headers\nwith pskb_pull() we should ensure the inner IP headers\nin ICMP errors from tunnels are present in the skb headroom\nfor functions like ipv4_update_pmtu(), icmp_send() and\nIP_VS_DBG().\n\nAlso, add more checks for the length of the inner headers.","state":0,"publishedAt":"2026-08-15T05:55:32.313+00:00","modifiedAt":"2026-10-16T18:55:17.469+00:00","affected":[{"ecosystem":"Vendor
