EUVD-2026-36113

Weblate is a web based localization tool. From version 5.15 to before version 2026.6, Weblate's VCSRESTRICTPRIVATE did not properly account for some transitional IPv6 ranges, multicast addresses, or some semi-private IPv4 ranges, which allowed some addresses to bypass private range restrictions...

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...

CVE-2026-49494

Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value taken from the IPv6 fixed header's payload length field by the size of each IPv6 extension header without validating it, so...

Comodo Internet Security's firewall driver Inspect.sys contains an integer underflow in its IPv6 packet parser. The parser decrements an unsigned 64-bit payload-length value taken from the IPv6 fixed header's payload length field by the size of each IPv6 extension header without validating it, so...

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...

kernel: ipv6: use RCU in ip6_xmit()

A use-after-free flaw was found in ip6autoflowlabel in the Linux kernel's net/ipv6/ip6output.c code. In this flaw an attacker can cause a denial of service DoS attack...

CVE-2026-50224

CVE-2026-50224 describes that the web administration panel binds broadly to the public IPv6 space on port [::]:8080 with no default firewall limits, making internal API endpoints reachable over the WAN. The NVD entry cites a network attack vector with low exploit complexity and no user interactio...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

CVE-2026-47674

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.21, the ip-restriction middleware hono/ip-restriction compares incoming IP addresses against configured deny and allow rules using string equality after partial normalization. Non-canonical IPv6...

CVE-2026-46172

In the Linux kernel, the following vulnerability has been resolved: ipv6: xfrm6: release dst on error in xfrm6rcvencap xfrm6rcvencap performs an IPv6 route lookup when the skb does not already have a dst attached. ip6routeinputlookup returns a referenced dst entry even when the lookup resolves to...

CVE-2026-45850

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. A remote attacker could send specially crafted IPv6 packets with extension headers, causing the system to fail protocol checksum validation. This could lead to incorrect packet processing or a denial of service DoS, impactin...
