UBUNTU-CVE-2023-1390
Vulnerability in linux-aws (UBUNTU-CVE-2023-1390)
Summary
Vulnerability in linux-aws (UBUNTU-CVE-2023-1390). Risk of unauthorized operations or information disclosure. Mitigation: upgrade to 4.4.0-1118.124 or later.
Original description
The description as published by the source.
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.
