EUVD-2026-72871

snipe-it versions before 8.7.0 contain a server-side request forgery vulnerability in the ExternalUrl validation rule that fails to detect IPv6 transition addresses encoding private IPv4 targets. Attackers with super-admin privileges can configure webhook URLs using NAT64, 6to4, or Teredo...

kernel: ipv6: anycast: insert aca into global hash under idev->lock

A flaw was found in the Linux kernel, specifically within its management of IPv6 anycast addresses. A timing issue, known as a race condition, can occur when these addresses are added and removed from a system's internal list. This can lead to the system attempting to access memory that has alrea...

kernel: ipv6: mcast: Fix use-after-free when processing MLD queries

A flaw was found in the Linux kernel's IPv6 multicast mcast component. When processing Multicast Listener Discovery MLD queries, a pointer to the multicast group address is not correctly reloaded after certain packet manipulations. This can lead to a use-after-free vulnerability, potentially...

kernel: ipv6: sit: reload inner IPv6 header after GSO offloads

A flaw was found in the Linux kernel's Simple Internet Transition SIT tunnel driver for IPv6. When processing network traffic with Generic Segmentation Offload GSO enabled, the driver may use a stale pointer to the inner IPv6 header after the socket buffer skb head has been reallocated. This can...

kernel: ipv6: prevent possible UaF in addrconf_permanent_addr()

A flaw was found in the Linux kernel's IPv6 networking subsystem. Specifically, a Use-after-Free UaF vulnerability exists within the addrconfpermanentaddr function. This issue arises when the system attempts to access an IPv6 address after it has been freed, which could allow an attacker to cause...

kernel: ipv6: add NULL checks for idev in SRv6 paths

A flaw was found in the Linux kernel. Missing null pointer checks in the IPv6 Segment Routing SRv6 implementation, specifically within the seg6hmacvalidateskb and ipv6srhrcv functions, can occur when an IPv6 device lacks proper configuration. This oversight may allow an attacker to trigger a null...

kernel: ipv6: fix possible UAF in icmpv6_rcv()

A flaw was found in the Linux kernel's IPv6 Internet Protocol version 6 implementation. This vulnerability, a Use-After-Free UAF error, occurs due to incorrect caching of network packet addresses before a memory operation. An attacker could potentially exploit this flaw to cause memory corruption...
