CVE-2024-26894 is a missing-release-of-memory flaw in the Linux kernel ACPI processor idle subsystem. In acpi_processor_power_exit(), the CPU idle device is unregistered but its associated allocation is not freed. Repeated execution of the affected CPU idle-device cleanup path can retain allocated kernel memory after the object’s effective lifetime.
