No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In binder_transaction of binder.c, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with no additional execution privileges needed.
