kernel: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

CVE-2026-10637 Use-after-free of `net_pkt` in IPv6 MLD send path triggerable by a link-local MLD Query

subsys/net/ip/ipv6mld.c:mldsend read the packet interface via netpktifacepkt after netsenddatapkt returned successfully. Per the network stack's ownership contract include/zephyr/net/netcore.h, and the explicit warning in subsys/net/ip/netcore.c:453-460 'do not use pkt after that call', a...

EUVD-2026-36327

Netty is a network application framework for development of protocol servers and clients. In netty-handler prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can bypass IPv6 subnet rules due to an incorrect masking operation in IpSubnetFilterRule.compareTo. Valid public IP addresses ca...

EUVD-2026-36255

Axios is a promise based HTTP client for the browser and Node.js. Prior to 0.32.0 and 1.16.0, Axios does not normalise IPv4-mapped IPv6 addresses. When NOPROXY lists an IPv4 address such as 127.0.0.1 or 169.254.169.254, a request URL using the IPv4-mapped IPv6 form ::ffff:7f00:1, ::ffff:a9fe:a9fe...

axios 服务端请求伪造漏洞

Axios is an open-source HTTP client developed by Axios, based on Promise a solution for asynchronous programming. There were code-related vulnerabilities in versions of Axios before 0.32.0 and 1.16.0. These vulnerabilities stemmed from unnormalized IPv4-to-Ipv6 address mappings, which could lead ...

Xcitium Client Security XCS before 13.8.2.10019 and Comodo Internet Security CIS through 12.3.4.8162 fix expected by 2026 Q3 contain an integer underflow vulnerability in the firewall driver Inspect.sys that allows remote unauthenticated attackers to crash the system by sending a crafted IPv6...

CVE-2026-8369

Improper Input Validation in the NAT64 translator in The OpenThread Authors OpenThread before commit 26a882d on all platforms allows an attacker on the adjacent IPv4 network to inject corrupted IPv6 packets into the Thread mesh or bypass security checks via crafted IPv4 packets with options...

kernel: ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

A flaw was found in the Linux kernel's IPv6 tunnel implementation. A remote attacker could exploit this flaw by sending malicious ICMPv6 error messages to cause a stack-based buffer overflow in the kernel's IPv4-over-IPv6 tunnel error handling code. This could result in a kernel crash denial of...
