Description:
SecurityLab Technologies has reported a vulnerability in OpenBSD, which can be exploited by malicious, local users to disclose potentially sensitive information.
The vulnerability is caused due to an input validation error in the "kernfs_xread()" function within the handling of user-supplied offset values. This can be exploited by a non-privileged process to read arbitrary kernel memory via the kernfs file system.
The vulnerability has been reported in OpenBSD version 3.8.
NOTE: The vendor reports that kernfs is not linked into the GENERIC kernel by default.
