NULL Pointer Dereference Vulnerability in Linux Kernel Affecting Red Hat and Other Distributions

CVE-2018-14646

What is CVE-2018-14646?

The Linux kernel before version 4.15-rc8 contains a vulnerability in the __netlink_ns_capable() function, which may allow a local attacker to exploit a NULL pointer dereference when a net namespace with a netnsid is assigned. This can potentially lead to a kernel panic, resulting in a denial of service. Users of affected distributions should update to the latest kernel version to mitigate this risk. For more information, consult the relevant Red Hat advisories.
