CVE-2022-50760
Published Dec 24, 2025
Modified Apr 15, 2026
Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios() As comment of pci_get_class() says, it returns a pci_device with its refcount increased and decreased the refcount for the input parameter @from if it is not NULL. If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we need to call pci_dev_put() to decrease the refcount. Add the missing pci_dev_put() to avoid refcount leak.

Frequently Asked Questions
What is CVE-2022-50760? +
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Fix PCI device refcount leak in amdgpu_atrm_get_bios()
As comment of pci_get_class() says, it returns a pci_device with its
refcount increased and decreased the refcount for the input parameter
@from if it is not NULL.
If we break the loop in amdgpu_atrm_get_bios() with 'pdev' not NULL, we
need to call pci_dev_put() to decrease the refcount. Add the missing
pci_dev_put() to avoid refcount leak.
How do I check if I'm vulnerable to CVE-2022-50760? +
