CVE-2026-46129

CVE-2026-46129 concerns the Linux kernel’s btrfs subsystem. In the create_space_info() error path, if kobject_init_and_add() fails, the chain leads to a double free of space_info due to both a direct kfree and a later release via space_info->kobj. The fix changes cleanup so that after kobject_...
