Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Initialise reader page order in rb_allocate_cpu_buffer() In rb_allocate_cpu_buffer(), bpage->order was omitted, leaving it as 0. This is an issue for a ring-buffer with subbufs bigger than PAGE_SIZE if when freed: free_buffer_page() relies on this value. Align the value with the actual allocation size (buffer::subbuf_order).
