{"id":"CVE-2019-15902","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-15902","generatedAt":"2026-10-29T02:46:29.839Z","title":"Misuse of the upstream \"x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()\" commit reintroduced the Spectre vulnerability that it aimed to eliminate.","description":"A backporting error was discovered in the Linux stable/longterm kernel 4.4.x through 4.4.190, 4.9.x through 4.9.190, 4.14.x through 4.14.141, 4.19.x through 4.19.69, and 5.2.x through 5.2.11. Misuse of the upstream \"x86/ptrace: Fix possible spectre-v1 in ptrace_get_debugreg()\" commit reintroduced the Spectre vulnerability that it aimed to eliminate. This occurred because the backport process depends on cherry picking specific commits, and because two (correctly ordered) code lines were swapped.","published":"2019-09-04T06:15:11.000Z","lastModified":"2026-06-17T02:21:18.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":5.6,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N"},"cwe":["CWE-200"],"affected":["linux/linux kernel","netapp/active iq performance analytics services","netapp/service processor","debian/debian linux","opensuse/leap","netapp/baseboard management controller firmware"],"epss":{"score":0.00609,"percentile":0.48934,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.61%).
