Detail

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

ACPI: processor_idle: Fix memory leak in acpi_processor_power_exit()

After unregistering the CPU idle device, the memory associated with it is not freed, leading to a memory leak:

unreferenced object 0xffff896282f6c000 (size 1024):
comm "swapper/0", pid 1, jiffies 4294893170
hex dump (first 32 bytes):

Fix this by freeing the CPU idle device after unregistering it.
