Junos OS and Junos OS Evolved: An attacker causes remote code execution or denial of service when service-deployment processing is used

Published Oct 14, 2026 · corrected/updated Oct 16, 2026 · Juniper Networks Junos OS · evidence confidence high

A Heap-based Buffer Overflow vulnerability in the sdxd service-deployment daemon of Juniper Networks Junos OS and Junos OS Evolved allows a remote unauthenticated attacker who can control or intercept the configured SDX/SRC server connection to execute code as root or cause denial of service via a crafted frame received over the service-deployment TCP connection.

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2026-102175 is a critical public vulnerability record for Juniper Networks Junos OS. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Juniper Networks Junos OS is in your estate, then compare installed versions with the affected ranges.
