Details

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.

Severity

5.5 (Medium)
