Description OSIDB Bzimport 2026-09-11 22:28:07 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ring-buffer: Free cpu_buffer::free_page with subbuf_order

When sub-buffers use an order greater than 0, cpu_buffer->free_page is
allocated with subbuf_order. Use the correct order for
cpu_buffer->free_page.
