  "details": "In the Linux kernel, the following vulnerability has been resolved:  xfrm: iptfs: only publish mode_data after clone setup  iptfs_clone_state() stores x-\u003emode_data before allocating the reorder window. If that allocation fails, the code frees the cloned state and returns -ENOMEM, leaving x-\u003emode_data pointing at freed memory.  The xfrm clone unwind later runs destroy_state() through x-\u003emode_data, so the failed clone path tears down IPTFS state that clone_state() already freed.  Keep the cloned IPTFS state private until all allocations succeed so failed clones leave x-\u003emode_data unset. The destroy path already handles a NULL mode_data pointer.",
