NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out." } ] }, "impact": { "cvss": [ [ { "vectorString": "6.5/CVSS:3.0/AV:A/AC:H/PR:L/UI:N/S:C/C:N/I:L/A:H", "version": "3.0" } ] ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-416" } ] } ] }, "references": { "reference_data": [ { "name": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16884", "refsource": "CONFIRM", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16884" }, { "name": "106253", "refsource": "BID", "url": "http://www.securityfocus.com/bid/106253" }, { "name": "https://patchwork.kernel.org/patch/10733769/", "refsource": "CONFIRM", "url": "https://patchwork.kernel.org/patch/10733769/" }, { "name": "https://patchwork.kernel.org/cover/10733767/", "refsource": "CONFIRM", "url": "https://patchwork.kernel.org/cover/10733767/" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20190327 [SECURITY] [DLA 1731-1] linux security update", "url": "https://lists.debian.org/debian-lts-announce/2019/03/msg00034.html" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20190401 [SECURITY] [DLA 1731-2] linux regression update", "url": "https://lists.debian.org/debian-lts-announce/2019/04/msg00004.html" }, { "refsource": "UBUNTU", "name": "USN-3932-1", "url": "https://usn.ubuntu.com/3932-1/" }, { "refsource": "UBUNTU", "name": "USN-3932-2", "url": "https://usn.ubuntu.com/3932-2/" }, { "refsource": "CONFIRM", "name": "https://support.f5.com/csp/article/K21430012", "url": "https://support.f5.com/csp/article/K21430012" }, { "refsource": "MLIST", "name": "[debian-lts-announce] 20190503 [SECURITY] [DLA 1771-1] linux-4.9 security update", "url": "https://lists.debian.org/debian-lts-announce/2019/05/msg00002.html" }, { "refsource": "UBUNTU", "name": "USN-3981-1", "url": "https://usn.ubuntu.com/3981-1/" }, { "refsource": "UBUNTU", "name": "USN-3980-1", "url": "https://usn.ubuntu.com/3980-1/" }, { "refsource": "UBUNTU", "name": "USN-3980-2", "url": "https://usn.ubuntu.com/3980-2/" }, { "refsource": "UBUNTU", "name": "USN-3981-2", "url": "https://usn.ubuntu.com/3981-2/" }, { "refsource": "REDHAT", "name": "RHSA-2019:1873", "url": "https://access.redhat.com/errata/RHSA-2019:1873" }, { "refsource": "REDHAT", "name": "RHSA-2019:1891", "url": "https://access.redhat.com/errata/RHSA-2019:1891" }, { "refsource": "REDHAT", "name": "RHSA-2019:2696", "url": "https://access.redhat.com/errata/RHSA-2019:2696" }, { "refsource": "REDHAT", "name": "RHSA-2019:2730", "url": "https://access.redhat.com/errata/RHSA-2019:2730" }, { "refsource": "REDHAT", "name": "RHSA-2019:3309", "url": "https://access.redhat.com/errata/RHSA-2019:3309" }, { "refsource": "REDHAT", "name": "RHSA-2019:3517", "url": "https://access.redhat.com/errata/RHSA-2019:3517" }, { "refsource": "REDHAT", "name": "RHSA-2020:0204", "url": "https://access.redhat.com/errata/RHSA-2020:0204" } ] } }
