VuXML IDDescription
759059ac-dab3-11e7-b5af-a4badb2f4699FreeBSD -- Information leak in kldstat(2)

Problem Description:

The kernel does not properly clear the memory of the kld_file_stat structure before filling the data. Since the structure filled by the kernel is allocated on the kernel stack and copied to userspace, a leak of information from the kernel stack is possible.

Impact:

Some bytes from the kernel stack can be observed in userspace.
