CVE-2026-33786

CVE-2026-33786

Description

An Improper Check for Unusual or Exceptional Conditions vulnerability in the chassis control daemon (chassisd) of Juniper Networks Junos OS on SRX1600, SRX2300 and SRX4300 allows a local attacker with low privileges to cause a complete Denial of Service (DoS).

When a specific 'show chassis' CLI command is executed, chassisd crashes and restarts which causes a momentary impact to all traffic until all modules are online again.

This issue affects Junos OS on SRX1600, SRX2300 and SRX4300:

  • 24.4 versions before 24.4R1-S3, 24.4R2.

This issue does not affect Junos OS versions before 24.4R1.
