CVE-2023-52936 Information

Description

In the Linux kernel the following vulnerability has been resolved:

kernel/irq/irqdomain.c: 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.
