Linux Distros Unpatched Vulnerability : CVE-2026-41417

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Netty allows request-line validation to be bypassed when a DefaultHttpRequest or DefaultFullHttpRequest is created first and its URI is later changed via setUri...

GHSA-RWM7-X88C-3G2P Netty epoll transport denial of service via RST on half-closed TCP connection

Summary Netty's epoll transport fails to detect and close TCP connections that receive a RST after being half-closed, leading to stale channels that are never cleaned up and, in some code paths, a 100% CPU busy-loop in the event loop thread. Affected versions All versions of 4.2.x...

Missing Release of Resource after Effective Lifetime

Overview Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime in the handling of TCP connections with ALLOWHALFCLOSURE enabled when a remote peer sends a FIN followed by a RST. An attacker can cause resource exhaustion or high CPU utilization by...

netty: Netty: Denial of Service via HTTP/2 CONTINUATION frame flood

A flaw was found in Netty. A remote user can trigger a Denial of Service DoS against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume...

io.netty/netty-codec-http: Netty: Request smuggling via incorrect parsing of HTTP/1.1 chunked transfer encoding extension values

A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/1.1 chunked transfer encoding extension values. Due to incorrect parsing of quoted strings, this flaw enables request smuggling attacks, potentially allowing an attacker to bypass...
