Linux Kernel Octeon EP Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's Octeon EP driver. The issue arises in the 'octep_device_setup()' function, where certain errors related to unsupported devices and mailbox initialization were not properly handled. This oversight left allocated memory unfreed, leading to a potential memory leak. The vulnerability has been addressed by adding appropriate memory deallocation and unmapping instructions to manage the errors correctly.

Impact

Exploitation of this vulnerability could lead to a memory leak, causing increased memory usage and potentially degrading system performance over time.
