Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved: interconnect: debugfs: initialize src_node and dst_node to empty strings The debugfs_create_str() API assumes that the string pointer is either NULL or points to valid kmalloc() memory. Leaving the pointer uninitialized can cause problems. Initialize src_node and dst_node to empty strings before creating the debugfs entries to guarantee that reads and writes are safe. A flaw was found in the Linux kernel’s interconnect debugfs test client. This vulnerability arises from the use of uninitialized pointers when handling debugfs entries. A local user with sufficient privileges could exploit this by accessing these debugfs entries. Successful exploitation could lead to a kernel crash, causing a local denial of service (DoS). There is also a theoretical risk of memory corruption.Details
