      <title>CVE-2026-21918 — Junos OS: SRX and MX Series: When TCP packets occur in a specific sequence flowd crashes</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-21918</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Juniper Networks Junos OS&lt;/p&gt;
&lt;p&gt;A Double Free vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX and MX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). On all SRX and MX Series platforms, when during TCP session establishment a specific sequence of packets is encountered a double free happens. This causes flowd to crash and the respective FPC to restart.&lt;/p&gt;
&lt;p&gt;This issue affects Junos OS on SRX and MX Series:&lt;/p&gt;
&lt;p&gt;*  all versions before 22.4R3-S7,
  *  23.2 versions before 23.2R2-S3,
  *  23.4 versions before 23.4R2-S4,
  *  24.2 versions before 24.2R2.&lt;/p&gt;</description>
