{"cve":"CVE-2017-15129","nvd":{"published":"2018-01-09T19:29:00.217","modified":"2026-06-17T01:07:18.013","status":"Modified","description":"A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=21b5944350052d2583e82dd59b19a9ba94a007f0","http://seclists.org/oss-sec/2018/q1/7","http://www.securityfocus.com/bid/102485","https://access.redhat.com/errata/RHSA-2018:0654","https://access.redhat.com/errata/RHSA-2018:0676"],"products":["canonical:ubuntu_linux","fedoraproject:fedora","linux:linux_kernel","redhat:enterprise_linux","redhat:enterprise_linux_compute_node_eus","redhat:enterprise_linux_desktop","redhat:enterprise_linux_eus","redhat:enterprise_linux_for_ibm_z_systems","redhat:enterprise_linux_for_ibm_z_systems_eus","redhat:enterprise_linux_for_power_big_endian","redhat:enterprise_linux_for_power_big_endian_eus","redhat:enterprise_linux_for_power_little_endian_eus","redhat:enterprise_linux_for_real_time","redhat:enterprise_linux_for_real_time_for_nfv","redhat:enterprise_linux_for_scientific_computing","redhat:enterprise_linux_server","redhat:enterprise_linux_server_aus","redhat:enterprise_linux_server_tus","redhat:enterprise_linux_server_update_services_for_sap_solutions","redhat:enterprise_linux_workstation"],"source":"nvd","synced_at":"2026-10-19T20:47:56.471723566+00:00"},"epss":{"cve":"CVE-2017-15129","score":0.00357,"percentile":0.29483,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
