An Arm product family through 2022-06-29 has a TOCTOU Race Condition that allows non-privileged user to make improper GPU processing operations to gain access to already freed memory.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
