Major		Junos OS and Junos OS Evolved: When a specifically malformed BGP route update is received RPD crashes (CVE-2026-33801)
Product-Group=evo
Severity=Major		An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to send a specific BGP update over an established BGP session to cause a Denial-of-Service (DoS). Please refer to https://supportportal.juniper.net/JSA110076 [juniper.net] for more information.

Major		On all Junos Evolved QFX platforms IPv6 static /56 routes stop forwarding traffic after route reprocessing triggered by topology changes
Product-Group=evo
Severity=Major		On all Junos Evolved QFX platforms, IPv6 traffic destined to networks reachable through affected IPv6 static /56 routes stops forwarding after topology changes such as reboots or link flaps cause route reprocessing. This results in loss of IPv6 connectivity for the affected prefixes.

Minor		Junos OS Evolved QFX5K platforms experience traffic loss after single-commit IRB interface renumbering
Product-Group=evo
Severity=Minor		On Junos OS Evolved QFX5K platforms, when an existing Integrated Routing and Bridging (IRB) interface is renumbered by deleting the existing IRB unit, creating a new IRB unit, and reassigning the associated Virtual Local Area Network (VLAN) Layer 3 interface in a single commit, the renumbered IRB interface remains Up/Up but stops forwarding traffic. Address Resolution Protocol (ARP) entries do not populate in IPv4 configurations, and Neighbor Discovery (ND) entries do not populate in IPv6 configurations. This results in complete traffic loss through the affected IRB interface and its associated VLAN.

Major		Interfaces et-0/0/0 and et-0/0/1 remain down in low-power state following a picd process restart
Product-Group=evo
Severity=Major		On QFX5130-48CM platforms, when the Physical Interface Card (PIC) daemon (picd) restarts, interfaces et-0/0/0 and et-0/0/1 will go down and fail to recover, resulting in traffic loss on both ports.

Major		Intermittent interface flaps observed on QFX platforms on 400G interfaces
Product-Group=evo
Severity=Major		On Junos OS Evolved QFX220 and QFX5130 platforms, the devices can experience intermittent interface flaps on 400G transceiver ports. As a result, traffic carried over the affected 400G interfaces may be disrupted. These flaps occur very infrequently and are considered rare events
