The cumulative Virtuozzo ReadyKernel patch was updated with security and stability fixes. The patch applies to Virtuozzo kernels 3.10.0-862.9.1.vz7.63.3 (7.0.8) and 3.10.0-862.11.6.vz7.64.7 (7.0.8 HF1).
Vulnerability id: CVE-2018-14646
The Linux kernel was found to be vulnerable to a NULL pointer dereference bug in the __netlink_ns_capable() function in the net/netlink/af_netlink.c file. A local attacker could exploit this when a net namespace with a netnsid is assigned to cause a kernel panic and a denial of service.
