Vulnerability from github – Published: 2026-06-25 09:31 – Updated: 2026-06-25 09:31

Details

In the Linux kernel, the following vulnerability has been resolved:

thunderbolt: Bound root directory content to block size

__tb_property_parse_dir() does not check that content_offset + content_len fits within block_len for the root directory case. When rootdir->length equals or exceeds block_len - 2, the entry loop reads past the allocated property block.

Add a bounds check after computing content_offset and content_len to reject directories whose content extends past the block.
