Linux Kernel Refcount Leak Vulnerability in ARM BCM Component

A refcount leak vulnerability has been identified in the ARM BCM component of the Linux kernel. The issue arises in the function 'bcm_kona_smc_initof_find_matching_node()', which returns a node pointer with an incremented reference count. The vulnerability occurs because the function does not properly decrement the reference count when the node is no longer needed, leading to a memory management issue.

Impact

Exploitation of this vulnerability causes a refcount leak, which can lead to memory management issues such as increased memory usage or potential memory corruption.
