{"id":"CVE-2019-13272","url":"https://www.cyber-defence.io/tools/cve/CVE-2019-13272","generatedAt":"2026-10-29T00:42:21.274Z","title":"Linux Kernel Improper Privilege Management Vulnerability","description":"In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.","published":"2019-07-17T13:15:11.000Z","lastModified":"2026-06-17T02:16:26.000Z","status":"Analyzed","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["linux/linux kernel","debian/debian linux","fedoraproject/fedora","canonical/ubuntu linux","redhat/enterprise linux","redhat/enterprise linux for arm 64","redhat/enterprise linux for ibm z systems","redhat/enterprise linux for real time","redhat/enterprise linux for real time for nfv","redhat/enterprise linux for real time for nfv tus","redhat/enterprise linux for real time tus","netapp/aff a700s firmware","netapp/h410c firmware","netapp/h610s firmware","netapp/active iq unified manager","netapp/e-series performance analyzer","netapp/e-series santricity os controller","netapp/hci management node","netapp/service processor","netapp/solidfire","netapp/steelstore cloud integrated storage","netapp/hci compute node"],"epss":{"score":0.52199,"percentile":0.98953,"date":"2026-10-27","history":[]},"kev":{"listed":true,"dateAdded":"2021-12-10","dueDate":"2022-06-10","knownRansomwareCampaignUse":"Unknown","notes":"Apply updates per vendor instructions.\nhttps://nvd.nist.gov/vuln/detail/CVE-2019-13272"},"exploits":{"count":4,"verified":true,"firstPublished":"2019-07-17","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":50541,"kind":"exploit","title":"Linux Kernel 5.1.x - 'PTRACE_TRACEME' pkexec Local Privilege Escalation (2)","url":"https://www.exploit-db.com/exploits/50541","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/50541.c","file":"exploits/linux/local/50541.c","published":"2021-11-23","added":"2021-11-23","updated":"2021-11-23","author":"Ujas Dhami","type":"local","platform":"linux","port":null,"verified":false,"codes":["CVE-2019-13272"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":null},{"edbId":47543,"kind":"exploit","title":"Linux Polkit - pkexec helper PTRACE_TRACEME local root (Metasploit)","url":"https://www.exploit-db.com/exploits/47543","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/47543.rb","file":"exploits/linux/local/47543.rb","published":"2019-10-24","added":"2019-10-24","updated":"2019-10-24","author":"Metasploit","type":"local","platform":"linux","port":null,"verified":true,"codes":["CVE-2019-13272"],"tags":"Metasploit Framework (MSF)","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/linux/local/ptrace_traceme_pkexec_helper.rb"},{"edbId":47163,"kind":"exploit","title":"Linux Kernel 4.10 < 5.1.17 - 'PTRACE_TRACEME' pkexec Local Privilege Escalation","url":"https://www.exploit-db.com/exploits/47163","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/47163.c","file":"exploits/linux/local/47163.c","published":"2019-07-24","added":"2019-07-26","updated":"2019-07-26","author":"bcoles","type":"local","platform":"linux","port":null,"verified":false,"codes":["CVE-2019-13272"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://github.com/bcoles/kernel-exploits/blob/a0b44c8c987bb33ab6535415cac3a4a9df09106e/CVE-2019-13272/poc.c"},{"edbId":47133,"kind":"exploit","title":"Linux - Broken Permission and Object Lifetime Handling for PTRACE_TRACEME","url":"https://www.exploit-db.com/exploits/47133","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/linux/local/47133.txt","file":"exploits/linux/local/47133.txt","published":"2019-07-17","added":"2019-07-17","updated":"2019-07-17","author":"Google Security Research","type":"local","platform":"linux","port":null,"verified":true,"codes":["CVE-2019-13272"],"tags":"Local","aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://bugs.chromium.org/p/project-zero/issues/detail?id=1903"}]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 10 June 2022).
