CVE-2026-74602

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