tag_insight = "The process file system, procfs(5), implements a view of the system
process table inside the file system.  It is normally mounted on
/proc, and is required for the complete operation of programs such as
ps(1) and w(1).

The Linux process file system, linprocfs(5), emulates a subset of
Linux's process file system and is required for the complete operation
of some Linux binaries.

The procfs and linprocfs implementations use uiomove(9) and the
related `struct uio' in order to fulfill read and write requests.
Several cases were identified where members of `struct uio' were not
properly validated before being used.  In particular, the `uio_offset'
member may be negative or extremely large, and was used to compute the
region of kernel memory to be returned to the user.";
