Quick assessment

Affected
Imagination Technologies Graphics DDK
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

以非特权用户身份安装和运行的软件，可能会执行不当的 GPU 驱动 IOCTL 调用，从而创建一个分配场景，当该分配被释放时，会导致双重释放（double free）和内核堆损坏。 该场景是通过在分配接口上构造特定的标志位组合而引发的，这种组合会导致在释放时发生不正确的双重释放事件。
