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

staging: pi433: 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. This requires saving off the root directory dentry to make

creation of individual device subdirectories easier.
