CVE-2023-1390

A remote denial of service vulnerability was found in the Linux kernel’s
TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown
state while attempting to parse SKBs, which are not in the queue. Sending
two small UDP packets to a system with a UDP bearer results in the CPU
utilization for the system to instantly spike to 100%, causing a denial of
service condition.
