AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a reference count leak in the Linux kernel's serial driver (ucc_uart.c). Specifically, the function soc_info() calls of_find_node_by_type(), which returns a node pointer with an incremented reference count. The code fails to call of_node_put() to decrement the reference count when the node is no longer needed, causing a refcount leak.
How can this vulnerability impact me? :
The reference count leak can lead to resource leaks in the kernel, potentially causing increased memory usage or instability over time. However, no direct impact such as privilege escalation or data corruption is described.
