CVE-2026-102176
HighCVSS 8.8Summary
A Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in the SDK service process of Juniper Networks Junos OS allows an unauthenticated network attacker to cause a denial of service or compromise the Routing Engine by sending specific packets when the SDK service and a JDAF routing instance are enabled.
Risk Assessment
This can disrupt device operation or compromise the Routing Engine, potentially leading to serious network security breaches.
Recommendation
Upgrade Junos OS to patched versions; restrict network access to devices with the SDK service and JDAF routing instance enabled.
Other vulnerabilities in Junos OS
See all- CVE-2026-33798High
A Stack-based Buffer Overflow vulnerability in the srxpfe of Juniper Networks Junos OS and Junos OS Evolved on the SRX Series. An L2-adjacent attacker can execute arbitrary code as root via high-availability fabric traffic.
- CVE-2026-33795High
A Numeric Truncation Error vulnerability in the rpd process of Juniper Networks Junos OS and Junos OS Evolved. An unauthenticated network-based attacker can cause a denial of service via a BGP Prefix-SID route advertisement that is subsequently re-advertised.
- CVE-2026-103994High
A Heap-based Buffer Overflow vulnerability in the VXLAN Gateway Daemon (vgd) of Juniper Networks Junos OS. A malicious or compromised SDN-controller can cause a complete outage of the OVSDB control plane and possibly remote code execution.
- CVE-2026-102185High
A Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. A remote network attacker can cause a denial of service via EVPN multihoming with preference-based designated-forwarder election.
- CVE-2026-102184High
An Improper Validation of Specified Quantity in Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos Evolved platforms. A configured EVPN signaling peer can cause an rpd crash via a malformed SRv6 structure carried in an EVPN route update, resulting in a denial of service affecting routing adjacencies.
- CVE-2026-102183High
An Improper Validation of Specified Quantity in Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved. A configured BGP EVPN peer can cause an rpd crash via a specifically malformed NLRI.
- CVE-2026-102180High
A Stack-based Buffer Overflow vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker with access to a configured BGP peering session to cause a denial of service by sending a crafted BGP route attribute, which is processed while a BGP RIB streaming telemetry subscription is active.
- CVE-2026-102179High
An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker with access to a configured BGP EVPN peer to cause a denial of service via BGP EVPN route processing when the l2vpn-evpn RIB telemetry sensor is subscribed.
- CVE-2026-102177High
An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent unauthenticated attacker to cause a denial of service when IS-IS link protection and backup-selection are configured.
- CVE-2026-102174High
A Stack-based Buffer Overflow vulnerability in the iked IKE key-management daemon of Juniper Networks Junos OS on the SRX Series allows an authenticated remote-access VPN client to execute code with root privileges or cause denial of service via the remote-access VPN authentication and JIMS identity-publishing path.
