  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nplatform/x86: lg-laptop: Fix LED resource handling\n\nThe event notification callback might access kbd_backlight even\nwhen it was not successfully registered with the LED subsystem.\nThe same happens inside acpi_remove(), where the LED devices are\nunregistered unconditionally.\n\nFix this by tracking the availability of the kbd_backlight LED\ndevice and use devm_led_classdev_register() to let devres take\ncare of unregistering the LED devices during removal. For this\nthe parent device of the LED devices is changed to the native\nplatform device.",
