# CVE-2022-50615

> 3.1 LOW

## Beschreibung

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().

## Patch verfügbar (OSV)

- Kernel ≥ 5.10.163
- Kernel ≥ 5.15.86
- Kernel ≥ 6.0.16
- Kernel ≥ 6.1.2
