Last modified
CVE-2018-14646 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. The Linux kernel before 4.15-rc8 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.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
