In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Hold cpu_buffer::lock when resizing a subbuf
Because, ring_buffer_subbuf_order_set() can clear cpu_buffer->free_page, hold cpu_buffer->lock to prevent races with ring_buffer_alloc_read_page() and ring_buffer_free_read_page().
