Descriptions

In the Linux kernel, the following vulnerability has been resolved:

ACPI: video: check for error while searching for backlight device parent

If acpi_get_parent() called in acpi_video_dev_register_backlight()
fails, for example, because acpi_ut_acquire_mutex() fails inside
acpi_get_parent), this can lead to incorrect (uninitialized)
acpi_parent handle being passed to acpi_get_pci_dev() for detecting
the parent pci device.

Check acpi_get_parent() result and set parent device only in case of success.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ACPI: vídeo: comprueba si hay errores al buscar el dispositivo de retroiluminación principal. Si la llamada acpi_get_parent() en acpi_video_dev_register_backlight() fallo, por ejemplo, porque acpi_ut_acquire_mutex() fallo dentro de acpi_get_parent), esto puede provocar que se pase el identificador acpi_parent incorrecto (no inicializado) a acpi_get_pci_dev() para detectar el dispositivo pci principal. Verifique el resultado de acpi_get_parent() y configure el dispositivo principal solo en caso de éxito. Encontrado por el Centro de verificación de Linux (linuxtesting.org) con SVACE.
