Description
In the Linux kernel, the following vulnerability has been resolved:
drivers: base: component: 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.
Affected configurations
• linux linux kernel (< 5.15.100)
• linux linux kernel (>= 5.16 < 6.1.18)
• linux linux kernel (>= 6.2 < 6.2.5)
