CVE-2026-21918 is a high-severity double free vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS running on SRX and MX Series devices. An unauthenticated attacker can trigger this flaw remotely by sending a specific sequence of TCP packets during session establishment, causing flowd to crash and the Flexible PIC Concentrator (FPC) to restart, resulting in a denial-of-service (DoS). This vulnerability affects multiple Junos OS versions prior to 22.4R3-S7, 23.2R2-S3, 23.4R2-S4, and 24.2R2. Exploitation requires no authentication or user interaction and impacts availability without compromising confidentiality or integrity. No known exploits are currently reported in the wild. European organizations using Juniper SRX or MX Series devices should prioritize patching to prevent potential service disruptions, especially in critical network infrastructure.
