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.","publishedAt":"2018-01-09T19:00:00.000Z","updatedAt":"2024-08-05T19:50:15.698Z","severity":null,"assigner":"redhat","products":["n/a Linux kernel v4.0-rc1 through v4.15-rc5"],"affected":[{"vendor":"n/a","product":"Linux kernel v4.0-rc1 through v4.15-rc5","versions":[{"version":"Linux kernel v4.0-rc1 through v4.15-rc5","status":"affected"}]}],"references":["https://usn.ubuntu.com/3617-1/","https://usn.ubuntu.com/3619-2/","https://usn.ubuntu.com/3617-3/","https://marc.info/?l=linux-netdev&m=151370451121029&w=2","https://marc.info/?t=151370468900001&r=1&w=2","https://usn.ubuntu.com/3632-1/","https://bugzilla.redhat.com/show_bug.cgi?id=1531174","https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.14.11","https://github.com/torvalds/linux/commit/21b5944350052d2583e82dd59b19a9ba94a007f0","https://access.redhat.com/errata/RHSA-2018:1062","https://access.redhat.com/errata/RHSA-2018:0654","https://access.redhat.com/security/cve/CVE-2017-15129","http://www.securityfocus.com/bid/102485","http://seclists.org/oss-sec/2018/q1/7","https://access.redhat.com/errata/RHSA-2018:0676","http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=21b5944350052d2583e82dd59b19a9ba94a007f0","https://usn.ubuntu.com/3617-2/","https://usn.ubuntu.com/3619-1/","https://access.redhat.com/errata/RHSA-2019:1946"],"weaknesses":["CWE-362"],"ingestedAt":"2026-10-29T19:43:23.091Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2017/15xxx/CVE-2017-15129.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2017-15129","state":"PUBLISHED","datePublished":"2018-01-09T19:00:00.000Z","dateUpdated":"2024-08-05T19:50:15.698Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2017-10-08T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11.
