Description
In the Linux kernel, the following vulnerability has been resolved: perf/x86/intel/uncore: Fix reference count leak in snr_uncore_mmio_map() pci_get_device() will increase the reference count for the returned pci_dev, so snr_uncore_get_mc_dev() will return a pci_dev with its reference count increased. We need to call pci_dev_put() to decrease the reference count. Let's add the missing pci_dev_put().

Executive Summary

This vulnerability is a reference count leak in the Linux kernel's perf/x86/intel/uncore component. Specifically, the function snr_uncore_get_mc_dev() returns a pci_dev structure with an increased reference count due to pci_get_device(), but it fails to call pci_dev_put() to decrease the reference count, leading to a resource leak.

Impact Analysis

The reference count leak can cause resource exhaustion in the kernel, potentially leading to degraded system performance or instability over time as resources are not properly released.
