CWE-1050

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.

Affected configurations

• linux linux kernel (>= 4.3 < 4.9.253) • linux linux kernel (>= 4.10 < 4.14.217) • linux linux kernel (>= 4.15 < 4.19.170) • linux linux kernel (>= 4.20 < 5.4.92) • linux linux kernel (>= 5.5 < 5.10.10) • linux linux kernel 5.11
