Description

A flaw was found in the Linux kernel's btrfs filesystem. This vulnerability, a double free, occurs in the `create_space_info_sub_group()` function's error handling path. When `kobject_init_and_add()` fails, a memory region can be freed twice. This can lead to memory corruption, potentially resulting in a denial of service or other unpredictable system behavior.
