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

ACPI: button: Fix ACPI GPE handler leak during removal

Commit a7e23ec17fee ("ACPI: button: Install notifier for system events as well") changed the ACPI notify handler type for ACPI buttons to ACPI_ALL_NOTIFY, but it forgot to update acpi_button_remove() to reflect that change. This leads to leaking the notify handler past driver removal, which may cause a kernel crash to occur if ACPI notify on the given device is triggered after removing the driver, and causes a subsequent probe of the given device with the same driver to fail.

Address this by updating the acpi_remove_notify_handler() call in acpi_button_remove() as appropriate.
