Description
In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Fix PCI device refcount leak in radeon_atrm_get_bios() As comment of pci_get_class() says, it returns a pci_device with its refcount increased and decreased the refcount for the input parameter @from if it is not NULL. If we break the loop in radeon_atrm_get_bios() with 'pdev' not NULL, we need to call pci_dev_put() to decrease the refcount. Add the missing pci_dev_put() to avoid refcount leak.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a reference count leak in the Linux kernel's Radeon DRM driver, specifically in the function radeon_atrm_get_bios(). The issue occurs because the function fails to call pci_dev_put() to decrease the reference count of a PCI device when breaking a loop with a non-NULL device pointer, leading to a resource leak.


How can this vulnerability impact me? :

The impact of this vulnerability is a resource leak in the kernel due to unreleased PCI device references. Over time, this can lead to increased memory usage and potentially degrade system stability or performance.
