The exact timing conditions are outside an attacker's direct control.\n\nThis issue affects Junos OS on SRX Series:\n\n\n  *  All versions before 23.2R2-S7.7;\n  *  from 23.4 before 23.4R2-S8.13;\n  *  from 24.2 before 24.2R2-S5.5;\n  *  from 24.4 before 24.4R2-S4;\n  *  from 25.2 before 25.2R2-S1;\n  *  from 25.4 before 25.4R1-S2.","state":0,"publishedAt":"2026-10-14T16:24:12.356+00:00","modifiedAt":"2026-10-14T20:26:06.177+00:00","affected":[{"ecosystem":"Vendor product","name":"Junos OS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"platforms\": [\n                        \"SRX Series\"\n                    ],\n                    \"product\": \"Junos OS\",\n                    \"vendor\": \"Juniper Networks\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"23.2R2-S7.7\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"23.4R2-S8.13\",\n                            \"status\": \"affected\",\n                            \"version\": \"23.4\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"24.2R2-S5.5\",\n                            \"status\": \"affected\",\n                            \"version\": \"24.2\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"24.4R2-S4\",\n                            \"status\": \"affected\",\n                            \"version\": \"24.4\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"25.2R2-S1\",\n                            \"status\": \"affected\",\n                            \"version\": \"25.2\",\n                            \"versionType\": \"custom\"\n                        },\n                        {\n                            \"lessThan\": \"25.4R1-S2\",\n                            \"status\": \"affected\",\n                            \"version\": \"25.4\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"},{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/AU:Y/R:A/RE:M","score":8.2,"severity":"HIGH"}],"references":["https://supportportal.juniper.net/JSA112170"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-102086","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-102086","identifiers":["CVE-2026-102086"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
