Linux Kernel Memory Leak Vulnerability in ngbe Probe Function

Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's ngbe network driver. When the ngbe_sw_init() function is called, memory is allocated for the RSS key. However, if ngbe_sw_init() encounters an error, the allocated memory for the RSS key is not freed, leading to a memory leak. This vulnerability affects several versions of the Linux kernel.

Impact

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