CVE-2023-53355

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> staging: pi433: fix memory leak with using debugfs_lookup()<br /> <br /> When calling debugfs_lookup() the result must have dput() called on it,<br /> otherwise the memory will leak over time. To make things simpler, just<br /> call debugfs_lookup_and_remove() instead which handles all of the logic<br /> at once. This requires saving off the root directory dentry to make<br /> creation of individual device subdirectories easier.
