Linux Kernel EDAC/Highbank Memory Leak Vulnerability

A memory leak vulnerability has been identified in the Linux kernel's EDAC/highbank component. The issue arises in the highbank_mc_probe() function, where the error handling path fails to release memory allocated by edac_mc_alloc() when devres_open_group() returns an error. This oversight leads to a memory leak.

Impact

Exploitation of this vulnerability causes a memory leak, which can lead to increased memory usage and potential exhaustion of system resources over time.
