CVE-2024-50093

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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: thermal: intel: int340x: procesador: Se corrige la advertencia durante la descarga del módulo. El controlador procesador_thermal utiliza pcim_device_enable() para habilitar un dispositivo PCI, lo que significa que el dispositivo se deshabilitará automáticamente al desconectar el controlador. Por lo tanto, no es necesario volver a llamar a pci_disable_device() en él. Con las recientes mejoras en la administración de recursos del dispositivo PCI, por ejemplo, la confirmación f748a07a0b64 ("PCI: Eliminar el legado pcim_release()"), este problema queda expuesto y activa la advertencia siguiente. [ 224.010735] proc_thermal_pci 0000:00:04.0: deshabilitando dispositivo ya deshabilitado [ 224.010747] ADVERTENCIA: CPU: 8 PID: 4442 en drivers/pci/pci.c:2250 pci_disable_device+0xe5/0x100 ...
