CVE-2026-74602

Not scored yetLast modified Oct 14, 2026

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).
