Overview
CVE-2026-74602 is a known-severity vulnerability. It was published on August 22, 2026.
Technical description
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).
