  "details": "In the Linux kernel, the following vulnerability has been resolved:  ring-buffer: Check resize_disabled before publishing the new subbuf order  ring_buffer_subbuf_order_set() stores the new order and only then walks the CPUs, returning -EBUSY if any of them has resizing disabled. A user mapped buffer has resizing disabled, and __rb_map_vma() reads buffer-\u003esubbuf_order without buffer-\u003emutex, so an mmap of an already mapped CPU racing the failing order change sizes the mapping with the new order and inserts pages past the sub-buffer into the VMA.  Check the CPUs before storing the new order.",
