Linux Kernel Refcount Leak Vulnerability in Power/Reset Component

A refcount leak vulnerability has been identified in the Linux kernel's power/reset component for arm-versatile systems. The issue arises in the 'versatile_reboot_probeof_find_matching_node_and_match()' function, which returns a node pointer with an incremented reference count. The vulnerability can be exploited by failing to release the reference when the node is no longer needed, leading to a memory management issue.

Impact

Exploitation of this vulnerability causes a memory refcount leak, which can lead to improper memory management and potential resource exhaustion.
