CVE-2024-38601 is a race condition in the Linux kernel ring-buffer subsystem. In rb_get_reader_page(), a reader swaps in a new reader page by updating one side of the doubly linked page list before updating the reciprocal link. During this transient inconsistency, a concurrent ring_buffer_resize() operation can invoke rb_check_pages(), detect inconsistent list pointers, and stop tracing. The condition became more likely after tracing was changed to stop the current tracer while resizing the buffer, although the race window remains small.
