Linux Kernel USB isp1362 Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's USB isp1362 driver. The issue arises when the debugfs_lookup() function is called; the resulting reference must be released with dput() to prevent memory leakage. Failure to do so can lead to a gradual increase in memory usage over time. The vulnerability has been addressed by modifying the code to use debugfs_lookup_and_remove(), which automatically manages the reference correctly, thereby eliminating the memory leak.

Impact

Exploitation of this vulnerability leads to a memory leak, causing increased memory usage over time, which can potentially degrade system performance.
