Oct 13 ENRICHED — CVE-2026-64013 (Linux). Received CVSS 5.5 and CPE data from NVD.
Description
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.
