Kinsmod
From Wikipedia, the free encyclopedia
- The correct title of this article is kinsmod. The initial letter is shown capitalized due to technical restrictions.
kinsmod is a program written by Silvio Cesare which, in the Linux operating system, allows the insertion of a potentially malicious Linux Kernel Module by writing to the /dev/kmem device, regardless of whether the kernel has been compiled with Linux Kernel Module support. The Grsecurity Linux kernel patch-set provides a safe guard against this security risk, providing an option "Deny writing to /dev/kmem". Note that on a correctly configured system only trusted users (normally only the administrator) are permitted to write to the /dev/kmem device and using kinsmod doesn't give a potential attacker any advantage.
