SUSE CVE-2026-74612
In the Linux kernel, the following vulnerability has been resolved: veth: fix skb length accounting after XDP frag adjustment veth exposes non-linear skb fragments through an xdpbuff. If an XDP program adjusts the fragment area, vethxdprcvskb copies xdpfragssize back to skb-datalen but leaves...
CVE-2026-74476
A flaw was found in the veth component of the Linux kernel. This vulnerability occurs when a specially crafted network packet, known as a fraglist skb socket buffer, is processed by the veth driver. An attacker could potentially send such a packet, causing the system to misinterpret fragment...
CVE-2026-74476 veth: convert frag_list skbs before running XDP
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...
CVE-2026-72493 net: serialize netif_running() check in enqueue_to_backlog()
In the Linux kernel, the following vulnerability has been resolved: net: serialize netifrunning check in enqueuetobacklog Syzbot reported a KASAN slab-use-after-free in fibruleslookup. The root cause is a race condition where packets can escape the backlog flushing during device unregistration...
The vulnerability of the veth_convert_skb_to_xdp_buff() function in the drivers/net/veth.c module of the network device driver for the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.
The vulnerability of the vethconvertskbtoxdpbuff function in the drivers/net/veth.c module of the Linux kernel network device driver is related to the reutilization of previously freed memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
