To protect against this, fail immediately if the next event pointer is less than 8 bytes from the end of the commit (last byte of data), as all events must be a minimum of 8 bytes anyway. That will cause rb_event_length() to read the next 4 bytes which could happen to be off the allocated page. But if the writer is in the process of updating that code, there's a small window where the length in the first 4 bytes could be zero even though the length is only 4 bytes. If the length in the first 4 bytes is zero then the length is stored in the second 4 bytes.

The checks to detect the corruption by the writer to reads needs to see the length of the event.

There's barriers to help detect this and handle it, but that code missed the case where the last event was at the very end of the page and has only 4 bytes left. In the Linux kernel, the following vulnerability has been resolved: ring-buffer: Do not attempt to read past 'commit' When iterating over the ring buffer while the ring buffer is active, the writer can corrupt the reader.
