CVE-2023-6679 is a medium severity vulnerability in Red Hat Enterprise Linux 9 involving a null pointer dereference in the Digital Phase Locked Loop (DPLL) subsystem of the Linux kernel. Specifically, the flaw exists in the dpll_pin_parent_pin_set() function within the dpll_netlink.c driver code. Exploiting this vulnerability can cause a denial of service (DoS) by crashing the kernel, impacting system availability. The vulnerability requires local access with low privileges and no user interaction, making exploitation somewhat limited but still feasible in certain scenarios. No known exploits are currently reported in the wild. European organizations running Red Hat Enterprise Linux 9 on critical infrastructure or servers could face service disruptions if targeted. Mitigation involves applying vendor patches once available and restricting local access to trusted users. Countries with significant Red Hat Enterprise Linux adoption and critical infrastructure reliance, such as Germany, France, and the UK, are most likely to be affected. The CVSS score of 5.
