- mt76: mt7915: Fix PCI device refcount leak in mt7915_pci_init_hif2()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
mt76: mt7915: Fix PCI device refcount leak in mt7915pciinit_hif2()
As comment of pcigetdevice() says, it returns a pcidevice with its refcount increased. We need to call pcidevput() to decrease the refcount. Save the return value of pcigetdevice() and call pcidev_put() to decrease the refcount.
