AI-suggested

A fix is available that adds the node write lock around the trace event to prevent concurrent access to freed links. Users should apply the official Linux kernel patch that addresses this issue to ensure memory safety in the TIPC subsystem.

Description

A use-after-free vulnerability in the Linux kernel's TIPC subsystem was fixed by adding a node write lock around the node reset trace dump. The flaw allowed a trace event to access a freed link pointer, causing a kernel memory safety issue detected by KASAN.
