Linux Kernel Net Scheduler Connection Tracking Race Condition Local Privilege Escalation Vulnerability

This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the processing of...

kernel: netfilter: nf_conntrack_helper: pass helper to expect cleanup

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackhelper. When a connection tracking helper is unregistered, its associated expectations are not properly cleaned up. This oversight can lead to a use-after-free vulnerability, where the system attempts t...

CVE-2026-12935: Stack-based Buffer Overflow

The TL-WR940N v6 router contains a vulnerability in its RTSP connection tracking module that can lead to a stack-based buffer overflow. The issue occurs when a LAN client initiates a connection to a malicious RTSP server controlled by an attacker. A specially crafted RTSP message may trigger...

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...

CVE-2026-63913 netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check

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...
