CVE-2024-46713

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> perf/aux: Fix AUX buffer serialization<br /> <br /> Ole reported that event-&gt;mmap_mutex is strictly insufficient to<br /> serialize the AUX buffer, add a per RB mutex to fully serialize it.<br /> <br /> Note that in the lock order comment the perf_event::mmap_mutex order<br /> was already wrong, that is, it nesting under mmap_lock is not new with<br /> this patch.
