"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: pcie: Fix integer overflow in iwl_write_to_user_buf\n\nAn integer overflow occurs in the iwl_write_to_user_buf() function,\nwhich is called by the iwl_dbgfs_monitor_data_read() function.\n\nstatic bool iwl_write_to_user_buf(char __user *user_buf, ssize_t count,\n\t\t\t\t void *buf, ssize_t *size,\n\t\t\t\t ssize_t *bytes_copied)\n{\n\tint buf_size_left = count - *bytes_copied;\n\n\tbuf_size_left = buf_size_left - (buf_size_left % sizeof(u32));\n\tif (*size > buf_size_left)\n\t\t*size = buf_size_left;\n\nIf the user passes a SIZE_MAX value to the \"ssize_t count\" parameter,\nthe ssize_t count parameter is assigned to \"int buf_size_left\".\nThen compare \"*size\" with \"buf_size_left\" . 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."
