CVE-2024-50093
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
thermal: intel: int340x: processor: Fix warning during module unload
The processor_thermal driver uses pcim_device_enable() to enable a PCI device, which means the device will be automatically disabled on driver detach. Thus there is no need to call pci_disable_device() again on it.
With recent PCI device resource management improvements, e.g. commit f748a07a0b64 ("PCI: Remove legacy pcim_release()"), this problem is exposed and triggers the warining below.
Remove the excess pci_disable_device() calls.
