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