CVE-2023-1390 (GCVE-0-2023-1390)

Vulnerability from cvelistv5 – Published: 2023-03-16 00:00 – Updated: 2026-09-18 15:03

Summary

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.

MSRC_CVE-2023-1390

Vulnerability from csaf_microsoft - Published: 2023-03-10 00:00 - Updated: 2023-04-17 00:00

Summary

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.
