Detailsinfo

A vulnerability was found in Linux Kernel (affected version not known). It has been declared as problematic. This vulnerability affects the function acpi_button_remove of the component ACPI GPE Handler. As an impact it is known to affect integrity, and availability. CVE summarizes:

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.

The advisory is available at git.kernel.org. This vulnerability was named CVE-2026-64013 since 07/19/2026. The exploitation appears to be easy. Local access is required to approach this attack.
