## Overview

In the Linux kernel, the following vulnerability has been resolved:

perf/dwc_pcie: fix duplicate pci_dev devices

During platform_device_register, wrongly using struct device
pci_dev as platform_data caused a kmemdup copy of pci_dev. Worse
still, accessing the duplicated device leads to list corruption as its
mutex content (e.g., list, magic) remains the same as the original.

## Affected

- `Linux >= af9597adc2f1e3609c67c9792a2469bb64e43ae9 < 0778c3e01a9f382a5bc444a5271e013406642501`
- `Linux >= af9597adc2f1e3609c67c9792a2469bb64e43ae9 < a71c6fc87b2b9905dc2e38887fe4122287216be9`
- `Linux >= af9597adc2f1e3609c67c9792a2469bb64e43ae9 < 7f35b429802a8065aa61e2a3f567089649f4d98e`
- `Linux 6.8`
