Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
gpu: host1x: Fix race in syncpt alloc/free<br />
<br />
Fix race condition between host1x_syncpt_alloc()<br />
and host1x_syncpt_put() by using kref_put_mutex()<br />
instead of kref_put() + manual mutex locking.<br />
<br />
This ensures no thread can acquire the<br />
syncpt_mutex after the refcount drops to zero<br />
but before syncpt_release acquires it.<br />
This prevents races where syncpoints could<br />
be allocated while still being cleaned up<br />
from a previous release.<br />
<br />
Remove explicit mutex locking in syncpt_release<br />
as kref_put_mutex() handles this atomically.
