"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: reserve space for the UTF-16 terminator in stream info\n\nsmb_strtoUTF16() always writes a terminating zero UTF-16 unit after the\nconverted characters, but get_file_stream_info() budgets only\nsizeof(struct smb2_file_stream_info) + streamlen * 2 for a stream entry\nand sizeof(struct smb2_file_stream_info) + 7 * 2 for the trailing\n\"::$DATA\" entry. When an entry exactly fills the 448-byte small response\nbuffer, the terminator is written two bytes past the allocation.\n\nReserve one extra UTF-16 unit in both budget checks. The terminator is\nnot part of the wire format, so the reported lengths are unchanged."
