CVE-2026-33796
CriticalCVSS 9.8Summary
A Stack-based Buffer Overflow vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured external BGP neighbor to execute arbitrary commands with root privileges via BMP route monitoring.
Risk Assessment
The vulnerability may allow an external BGP neighbor to execute arbitrary commands with root privileges on the device, posing a critical risk of compromise of network infrastructure. Exploitation requires a configured BGP neighbor and BMP route monitoring.
Recommendation
Apply the patches provided by Juniper Networks for Junos OS and Junos OS Evolved. Limit trust in external BGP neighbors and review the BMP route monitoring configuration.

- 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-2026-102176High
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.
