This is a race condition outside the attacker's direct control.\n\nThis issue affects Junos OS on SRX Series:\n\n\n  *  All versions before 23.2R2-S5;\n  *  from 23.4 before 23.4R2-S6;\n  *  from 24.2 before 24.2R2-S3;\n  *  from 24.4 before 24.4R2-S1;\n  *  from 25.2 before 25.2R1-S1, 25.2R2.","published":"2026-10-14T17:18:03.000Z","lastModified":"2026-10-15T16:24:19.000Z","status":"Awaiting Analysis","sourceIdentifier":"sirt@juniper.net","cvss":{"version":"4.0","score":8.2,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-416"],"affected":[],"epss":{"score":0.00329,"percentile":0.25805,"date":"2026-10-26","history":[{"date":"2026-10-15","score":0.00328,"percentile":0.24327}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.33%).
