CVE-2024-26894 | 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): 00 00 00 00 0b 00 00 00 00 00 00 00 00 00 00 00 ................ 00 00 00 00
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):
