When these jbufs are exhausted, the device stops forwarding all transit traffic.\n\nA jbuf memory leak can be noticed from the following logs:\n\n(<node>.)<fpc> Warning: jbuf pool id <#> utilization level (<current level>%) is above <threshold>%!\n\nTo recover from this issue, the affected device needs to be manually rebooted to free the leaked jbufs.\n\n\n\n\nThis issue affects Junos OS on SRX Series: \n\n  *  all versions before 21.2R3-S9,\n  *  21.4 versions before 21.4R3-S10,\n  *  22.2 versions before 22.2R3-S6,\n  *  22.4 versions before 22.4R3-S6,\n  *  23.2 versions before 23.2R2-S3,\n  *  23.4 versions before 23.4R2-S3,\n  *  24.2 versions before 24.2R2.","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/R:U/RE:M","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-401"],"references":["https://supportportal.juniper.net/JSA96469"],"products":["juniper:junos"],"source":"nvd","synced_at":"2026-10-19T22:00:57.946988208+00:00"},"epss":{"cve":"CVE-2025-30658","score":0.00424,"percentile":0.36735,"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).
