In the Linux kernel, the following vulnerability has been resolved:

kernel/fail function: fix memory leak with using debugfs lookup()

When calling debugfs lookup() the result must have dput() called on it,

otherwise the memory will leak over time. To make things simpler, just

call debugfs lookup and remove() instead which handles all of the logic

at once.
