If the memory is exhausted traffic processing will be impacted.\n\nUse the CLI command show security monitoring to monitor the memory utilization of the PFEs on the FPCs.\n\nThis issue affects Junos OS on SRX Series and MX Series:\n\n\n  *  23.4 versions from 23.4R2-S3 before 23.4R2-S7;\n  *  24.2 versions from 24.2R2 before 24.2R2-S3;\n  *  24.4 versions before 24.4R2-S3;\n  *  25.2 versions before 25.2R1-S2, 25.2R2.","categories":["Network & edge"],"product":"Junos OS","vendor":"Juniper Networks","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102081","source_modified_at":"2026-10-14T20:46:19.992Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Junos OS","vendor":"Juniper Networks","versions":[{"lessThan":"23.4R2-S7","status":"affected","version":"23.4R2-S3","versionType":"custom"},{"lessThan":"24.2R2-S3","status":"affected","version":"24.2R2","versionType":"custom"},{"lessThan":"24.4R2-S3","status":"affected","version":"24.4","versionType":"custom"},{"lessThan":"25.2R1-S2, 25.2R2","status":"affected","version":"25.2","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102081","source_modified_at":"2026-10-14T20:46:19.992Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Junos OS","ecosystem":null},"version":"23.4R2-S7","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102081","source_modified_at":"2026-10-14T20:46:19.992Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Junos OS","ecosystem":null},"version":"24.2R2-S3","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102081","source_modified_at":"2026-10-14T20:46:19.992Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Junos OS","ecosystem":null},"version":"24.4R2-S3","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102081","source_modified_at":"2026-10-14T20:46:19.992Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Junos OS","ecosystem":null},"version":"25.2R1-S2, 25.2R2","basis":"first unaffected version stated in the CVE record"}],"cvss":7.5,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00374,"percentile":0.30137,"score_date":"2026-10-23"},"published_at":"2026-10-14T16:26:14.921Z","modified_at":"2026-10-14T20:46:19.992Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102081","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T20:46:19.992Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102081","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://supportportal.juniper.net/JSA112177","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-14T20:38:49.370441Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-14T20:46:19.992Z","content_hash":"8e9fd38ca2f0154602e649aa40ab2d33a60cb5b38b17954033b01496b9d52cbf"}}
