CVE-2017-1088 Information

Description

In FreeBSD before 11.1-STABLE 11.1-RELEASE-p4 11.0-RELEASE-p15 10.4-STABLE 10.4-RELEASE-p3 and 10.3-RELEASE-p24 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. As a result some bytes from the kernel stack can be observed in userspace.
