In the Linux kernel, the following vulnerability has been resolved:
USB: isp1362: 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.

kernel: Linux kernel: Memory leak in USB ISP1362 driver causes Denial of Service
In the Linux kernel, the following vulnerability has been resolved:
USB: isp1362: 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.
A flaw was found in the Linux kernel's USB ISP1362 driver. A local user could exploit this memory leak vulnerability by repeatedly calling `debugfs_lookup()` without properly releasing the allocated memory. This oversight leads to a gradual depletion of system memory, which can result in a Denial of Service (DoS) condition.
