Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftct: Added an seqadj extension for natted connections. Sequence adjustment may be required for FTP traffic with PASV/EPSV modes. This is due to the need to rewrite the packet payload IP, port on the ftp control...

New NatJack Attacks Hijack TCP Sessions and Spoof DNS by Manipulating NAT Tables

Security researcher Malcolm Stagg has disclosed a new attack class called NatJack that manipulates network address translation NAT connection state to hijack active TCP sessions, spoof DNS responses, expose mapped ports, and exhaust NAT tables. Presented at Black Hat USA 2026, the research found...

CVE-2026-70485

Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.0, Open WebUI checked whether a user-supplied URL destination was globally routable by applying ipaddress.isglobal to the literal IPv6 address without examining IPv4 addresses embedded in...

CVE-2026-70485

CVE-2026-70485 – Open WebUI : Affected versions 0.9.0 through 0.11.0 of the Open WebUI self-hosted AI platform check whether a user-provided URL is globally routable by applying ipaddress.is_global to the literal IPv6 address, without considering embedded IPv4 in transition encodings. In NAT64 de...

GHSA-22JQ-VG5J-6VGG ip-address: misclassification of IPv4-mapped/NAT64 IPv6 addresses can bypass SSRF and trust-boundary checks

Summary Address6's special-property checks misclassify IPv4-mapped ::ffff:0:0/96 and NAT64 well-known 64:ff9b::/96 IPv6 addresses. These checks classify an address by its IPv6 wrapper rather than by the IPv4 address it embeds, so isLoopback, isLinkLocal, isMulticast, and isUnspecified all return...

CVE-2026-54272

ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Versions 10.1.1 through 10.2.0 are vulnerable to SSRF through misclassification of IPv4-mapped/NAT64 IPv6 addresses. Address6.getType classifies an address by matching it against a table of known IPv6...

CVE-2026-47695 CC-Tweaked has an SSRF Protection Bypass with NAT64

CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles, and more to the game. Prior to version 1.119.0, CC-Tweaked's HTTP API http.request, http.websocket blocks requests to private network ranges to prevent server-side request forgery SSRF. This protection can be bypassed ...

CVE-2026-47695

CC-Tweaked has an SSRF protection bypass via NAT64. Before version 1.119.0, the HTTP API endpoints (http.request, http.websocket) could be tricked into reaching internal IPv4 services by supplying a NAT64 address in the URL (example: http://[64:ff9b::]/). The NAT64 prefix 64:ff9b::/96 is not reco...

CVE-2026-63913

A flaw was found in the Linux kernel's netfilter conntrack TCP state machine. A remote attacker can exploit this vulnerability by sending a specially crafted sequence of TCP Transmission Control Protocol packets, specifically a SYN synchronize packet followed by an RST reset packet with an invali...

SUSE 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-2026-53368

A flaw was found in the Linux kernel's F2FS Flash-Friendly File System component. A race condition exists where the f2fsneeddentrymark function incorrectly reads natentry flags without proper synchronization during checkpoint operations. This can lead to an inconsistent inode block marking state,...
