When all available memory has been exhausted, jdhcpd will crash and restart which causes a complete service impact until the process has recovered.\n\nThe memory usage of jdhcpd can be monitored with:\n\nuser@host> show system processes extensive | match jdhcpd\n\n\n\nThis issue affects Junos OS:\n\n  *  all versions before 22.4R3-S1,\n  *  23.2 versions before 23.2R2,\n  *  23.4 versions before 23.4R2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/RE:M","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-401"],"references":["https://kb.juniper.net/JSA107820"],"products":["juniper:junos"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-33782","score":0.00288,"percentile":0.21138,"date":"2026-10-26"},"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).
