CVSS: 8.0EPSS: 0%CPEs: 12EXPL: 0CVE-2018-16884 – kernel: nfs: use-after-free in svc_process_common()
https://notcve.org/view.php?id=CVE-2018-16884
18 Dec 2018 — A flaw was found in the Linux kernel's NFS41+ subsystem. 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. Se ha encontrado un error en el subsistema de archivos NFS41+ del kernel de Linux. • http://www.securityfocus.com/bid/106253 • CWE-416: Use After Free •
