Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> interconnect: debugfs: initialize src_node and dst_node to empty strings<br /> <br /> The debugfs_create_str() API assumes that the string pointer is either NULL<br /> or points to valid kmalloc() memory. Leaving the pointer uninitialized can<br /> cause problems.<br /> <br /> Initialize src_node and dst_node to empty strings before creating the<br /> debugfs entries to guarantee that reads and writes are safe.
