CVE-2022-50718

Resource retention via unreleased PCI-device references

Published Dec 24, 2025 · Updated Dec 24, 2025

Resource leak in the Linux kernel amdgpu driver allows attackers to retain PCI-device references during display-audio power changes. The amdgpu_device_resume_display_audio() and amdgpu_device_suspend_display_audio() paths obtain a reference with pci_get_domain_bus_and_slot() but return without calling pci_dev_put(). The affected path requires an AMD GPU using the amdgpu display-audio power logic; published sources establish no consequence beyond persistent reference retention.
