CVE-2026-74559

CVE-2026-74559 affects the Linux kernel XDP/AF_XDP path. The issue arises in the xsk_build_skb() flow where, on overflow of descriptors (or invalid descriptors in fragmented packets), the generic transmit path multi-buffer handling could mishandle descriptors. The fix introduces xdp_sock::drain_c...

In the Linux kernel, the following vulnerability has been resolved: veth: convert fraglist skbs before running XDP A fraglist skb can reach veth with datalen set but nrfrags zero. vethconvertskbtoxdpbuff only converts skbs that are shared, locked, have frags, or do not have enough headroom. It...

CVE-2026-74476

The CVE-2026-74476 entry describes a Linux kernel vulnerability in the veth path where a frag_list skb can reach veth with data_len set but nr_frags zero. The root cause is that veth_convert_skb_to_xdp_buff() could expose frag_list data to XDP as if it were in frags[], even though frags[] is empt...
