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.

A vulnerability in the Linux kernel's ACPI button driver was resolved that involved a leak of the ACPI General Purpose Event (GPE) notify handler during driver removal. The issue occurred because the notify handler type was changed but the removal function was not updated accordingly, causing the handler to remain registered after the driver was removed. This could lead to a kernel crash if an ACPI notify event triggered after driver removal, and also cause subsequent driver probes to fail.
