Here, \"buf_size_left\" is a\nnegative number, so \"*size\" is assigned \"buf_size_left\" and goes into\nthe third argument of the copy_to_user function, causing a heap overflow.\n\nThis is not a security vulnerability because iwl_dbgfs_monitor_data_read()\nis a debugfs operation with 0400 privileges.",
