An Out-of-bounds Write vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS Evolved on QFX5240, QFX5241 and QFX5250 configured for BGP global-load-balancing and more than 128 ecmp next-hops allows an attacker to cause an rpd crash.

CVSS

Base score: 7.1
Version: 4.0
Vector: CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.27 %
Percentile among all scored CVEs: 18
Score date: 10/20/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
