CVE-2022-48973
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the Linux kernel, the following vulnerability has been resolved: gpio: amd8111: Fix PCI device reference count leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL input parameter, there is no problem for the 'Device not found' branch. For the normal path, add pci_dev_put() in amd_gpio_exit().

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

4.9.336, 4.14.302, 4.19.269, or 5.4.227 (or later stable release) depending on the currently deployed kernel branch
- Identify the currently running kernel version using 'uname -r'
- Check if the current version is within any of the affected ranges: >= 3.6 and < 4.9.336, >= 4.10 and < 4.14.302, >= 4.15 and < 4.19.269, >= 4.20 and < 5.4.227
- If affected, schedule a maintenance window for kernel upgrade
- Upgrade to a kernel version that includes the fix: 4.9.336+, 4.14.302+, 4.19.269+, 5.4.227+, or any stable release after these versions
- Reboot the system to load the patched kernel
- Verify the fix is applied by checking the kernel version and confirming the gpio-amd8111 driver loads without errors
