Continuous receipt of these MPLS packets causes resources to be exhausted. MPLS config is not required to be affected by this issue. \n\n\nThis issue affects Junos OS Evolved ACX 7000 Series: \n\n\n\n  *  All versions before 21.4R3-S9-EVO,\n  *  22.2-EVO before 22.2R3-S4-EVO, \n  *  22.3-EVO before 22.3R3-S3-EVO, \n  *  22.4-EVO before 22.4R3-S2-EVO, \n  *  23.2-EVO before 23.2R2-EVO, \n  *  23.4-EVO before 23.4R1-S1-EVO, 23.4R2-EVO.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:H","score":7.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","score":8.2},"cwes":["CWE-923"],"references":["https://supportportal.juniper.net/JSA83009"],"products":["juniper:junos_os_evolved"],"source":"nvd","synced_at":"2026-10-19T21:55:31.737901711+00:00"},"epss":{"cve":"CVE-2024-47490","score":0.00583,"percentile":0.47902,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
