Description
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7915: Fix PCI device refcount leak in mt7915_pci_init_hif2()
As comment of pci_get_device() says, it returns a pci_device with its
refcount increased. We need to call pci_dev_put() to decrease the
refcount. Save the return value of pci_get_device() and call
pci_dev_put() to decrease the refcount.

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a reference count leak in the Linux kernel's mt76 driver for the mt7915 PCI device. Specifically, the function mt7915_pci_init_hif2() calls pci_get_device(), which increases the device's reference count, but fails to call pci_dev_put() to decrease it, leading to 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 as device references are not properly released.
