  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nthunderbolt: Bound root directory content to block size\n\n__tb_property_parse_dir() does not check that content_offset +\ncontent_len fits within block_len for the root directory case.\nWhen rootdir->length equals or exceeds block_len - 2, the entry\nloop reads past the allocated property block.\n\nAdd a bounds check after computing content_offset and content_len\nto reject directories whose content extends past the block.",
