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...

CVE-2026-43037

CVE-2026-43037 affects the Linux kernel; vulnerability arises from ip4ip6_err() using a cloned skb where the IPv6 receive path writes cb[] as inet6_skb_parm, which is then misinterpreted as IPv4 inet_skb_parm by __ip_options_echo(), causing a potential data leak/compromise. The fix includes clear...

CVE-2026-43037 ip6_tunnel: clear skb2->cb[] in ip4ip6_err()

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip4ip6err Oskar Kjos reported the following problem. ip4ip6err calls icmpsend on a cloned skb whose cb was written by the IPv6 receive path as struct inet6skbparm. icmpsend passes IPCBskb2 to...

Linux kernel 缓冲区错误漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. The Linux kernel suffers from a buffer error vulnerability that stems from the ip4ip6err function failing to clear the cb array of skb2, which results in the IPv6 cb structure...

PT-2026-36454

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the ip4ip6 err function where it calls icmp send using a cloned socket buffer skb containing cb data written as struct inet6 skb parm. The icmp send function passes...
