AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a reference count leak in the Linux kernel's PCI microchip driver, specifically in the mc_pcie_init_irq_domains() function. The function of_get_next_child() returns a node pointer with an incremented reference count, which should be decremented using of_node_put() when no longer needed. However, mc_pcie_init_irq_domains() only calls of_node_put() in the normal execution path and misses it in some error paths, causing a reference count 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 in the system over time. This may degrade system performance or reliability, especially in environments relying on the affected PCI microchip driver.
