For example, an IPv4/TCP frame withskb->len == 65540 and nhoff == 34 gets thoff == 4, so callers such asskb_probe_transport_header() point the transport header inside theEthernet header.\nSuch skbs are not exotic:- At the time of commit d0c081b49137 (\"flow_dissector: properly cap  thoff field\"), AF_PACKET with PACKET_VNET_HDR could already build GSO  skbs larger than 64KB (MTU checks are skipped for GSO, and  alloc_skb_with_frags() accepted up to MAX_SKB_FRAGS (17) order-0  pages on top of the linear part).- BIG TCP now makes skbs larger than 64KB common.- The following patch makes tun_get_user() dissect IFF_TAP frames  before eth_type_trans() pulls the Ethernet header, so a GSO frame  carrying a 65522..65535 byte L3 packet will be dissected with  skb->len in [65536, 65549].\nCompare as u32 instead. If the resulting offset cannot be representedin the u16 key_control->thoff, cap it to U16_MAX and report thedissection as failed rather than silently returning a wrong transportoffset. thoff is still set on failure, as some callers (such aseth_get_headlen()) use it regardless of the return value.\nhttps://www.cve.org/CVERecord?id=CVE-2026-98955https://git.kernel.org/stable/c/d9e08836d06c84abb18470c94b12b131eaccdc7dhttps://git.kernel.org/stable/c/50d0cd575cab763f833d6ac6eb6550b23a0b3daehttps://git.kernel.org/stable/c/9993e6a0ac1b5b3101ffba702cacb9f42b9909d8https://git.kernel.org/stable/c/52efce4755a4b8b82039caa773645ffc80b25362https://git.kernel.org/stable/c/99bda1ecbd56905f8bd934b9cdccd3bd251192b1#kernel
