CVE-2026-74473

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN implementation. An incorrect buffer length check in the routeshortcircuit function, specifically when using pskbmaypull, can lead to reading beyond the allocated buffer length. This occurs when processing IP headers in non-linear...

SUSE CVE-2026-74474

In the Linux kernel, the following vulnerability has been resolved: vxlan: use pskbnetworkmaypull for transmit path header pulls In vxlanxmit, arpreduce, and vxlanmdbentryskbget, pskbmaypull was being called to verify the availability of network layer headers ARP, IPv6/ND, IP/IPv6 MDB keys...

CVE-2026-74473

In the Linux kernel, the following vulnerability has been resolved: vxlan: use pskbnetworkmaypull in routeshortcircuit routeshortcircuit currently calls pskbmaypullskb, sizeofstruct iphdr or ipv6hdr, which checks if bytes are available starting from skb-data. However, in vxlanxmit, skb-data point...

CVE-2026-74474

CVE-2026-74474 pertains to the Linux kernel where the transmit path in VXLAN code (vxlan_xmit, arp_reduce, vxlan_mdb_entry_skb_get) used pskb_may_pull() to verify network-layer header availability. Because skb->data points to the MAC header (offset ~ ETH_HLEN), pskb_may_pull() could fail to ac...

CVE-2026-74474 vxlan: use pskb_network_may_pull() for transmit path header pulls

In the Linux kernel, the following vulnerability has been resolved: vxlan: use pskbnetworkmaypull for transmit path header pulls In vxlanxmit, arpreduce, and vxlanmdbentryskbget, pskbmaypull was being called to verify the availability of network layer headers ARP, IPv6/ND, IP/IPv6 MDB keys...

CVE-2026-74473

CVE-2026-74473 affects the Linux kernel’s VXLAN path. The issue arises in route_shortcircuit() which originally used pskb_may_pull() to ensure a network header length, but skb->data points to the MAC header in vxlan_xmit(), making the check insufficient and risking reading beyond the pulled bu...

In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: fix and simplify IP6IP6 tunnel handling Fix nfflowip6tunnelproto to use pskbmaypull instead of skbheaderpointer to ensure the outer IPv6 header is in the skb headroom, which is required for subsequent packet...

CVE-2026-72233

In the Linux kernel, the batman-adv component (bla) vulnerability is resolved: pskb_may_pull() used by batadv_bla_is_backbone_gw() could reallocate the buffer behind the skb, making variables pointing to the old buffer prone to use-after-free. The issue is mitigated by the patch that ensures poin...
