  3. CVE-2026-23123
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.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad se ha resuelto: interconnect: debugfs: inicializar src_node y dst_node a cadenas vacías La API debugfs_create_str() asume que el puntero de cadena es NULL o apunta a memoria kmalloc() válida. Dejar el puntero sin inicializar puede causar problemas. Inicializar src_node y dst_node a cadenas vacías antes de crear las entradas debugfs para garantizar que las lecturas y escrituras sean seguras.
