发布于3月6日3月6日 Members SUSE: CVE-2023-1390: SUSE Linux Security Advisory Severity 8 CVSS (AV:N/AC:L/Au:N/C:N/I:N/A:C) Published 03/16/2023 Created 05/05/2023 Added 04/11/2023 Modified 01/28/2025 Description 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.
