CVE-2026-56179 Windows Network Address Translation (NAT) Spoofing Vulnerability

...

CVE-2026-72761

The CVE affects the webhook URL validator in website/notifications/webhooks.py, which uses ip.is_global after DNS resolution. IPv6 transition addresses (NAT64 64:ff9b::/96, 6to4 2002::/16, Teredo 2001:0000::/32) are categorized as globally routable by IANA, causing is_global to return True even w...

Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From version 2.0.14 to before version 2.1.0, authenticated users can claim the dashboard Host through NAT and preempt all dashboard routing. This issue has been patched in version 2.1.0...

CVE-2026-54272

The CVE affects the ip-address JavaScript library (versions 10.1.1–10.2.0). A misclassification of IPv4-mapped/NAT64 IPv6 addresses in Address6.getType() caused SSRF and trust-boundary issues by not normalizing mapped addresses to IPv4 before checks, due to the IPv6 special-use prefix table missi...

CVE-2026-63913

The CVE-2026-63913 entry concerns the Linux kernel netfilter conntrack TCP state machine. A crafted RST with an invalid SEQ after observing a SYN could transition the conntrack entry to TCP_CONNTRACK_CLOSE, even if the RST is not a valid response to the observed SYN or its direction. This could p...

CVE-2026-63913

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check An unintended behavior in the TCP conntrack state machine allows a connection to be forced into the CLOSE state using an RST packet with an...

CVE-2026-53374 drm/amdgpu: zero-initialize GART table on allocation

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: zero-initialize GART table on allocation GART TLB is flushed after unmapping but not after mapping. Since amdgpubocreatekernel does not zero-initialize the buffer, when a single PTE is written the TLB may speculativel...
