Description Cathy Hu 2023-06-26 07:20:59 UTC 
CVE-2023-1206

A flaw in the Linux Kernel found in the Linux kernel’s networking stack which permits attackers to force hash collisions in the IPv6 connection lookup table. This results in a significant increase in the cost of
lookups, causing increased CPU utilization. This significant CPU usage increase in the Linux kernel subjected to a modified form of the classic IPv6 SYN-Flood. The actual impact of this issue may be a denial of service (due to heightened CPU usage) to hosts which can receive malicious IPv6 traffic.
