CVE-2025-68732

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.
