A fix is available — apply it.

In the Linux kernel, the following vulnerability has been resolved:

gpu: host1x: Fix race in syncpt alloc/free

Fix race condition between host1x_syncpt_alloc() and host1x_syncpt_put() by using kref_put_mutex() instead of kref_put() + manual mutex locking.

This ensures no thread can acquire the syncpt_mutex after the refcount drops to zero but before syncpt_release acquires it. This prevents races where syncpoints could be allocated while still being cleaned up from a previous release.

Remove explicit mutex locking in syncpt_release as kref_put_mutex() handles this atomically.
