Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ARM Mali GPU是英国ARM公司的一款移动显示芯片组（GPUs）系列。和其他基于IP核心（IP cores）嵌入式技术的3D显示芯片一样，Mali显示芯片组没有提供特别用来驱动LCD显示器显示图像的显示控制器（类似于显卡），相反地，它是一个纯3D显示引擎，它将图像加载到缓存中，并且由专门负责图像显示处理的内置显示核心来显示这些图像。 Arm Mali GPU 内核驱动程序存在资源管理错误漏洞，该漏洞源于 GPU 内存操作处理不当，导致释放后使用。该漏洞允许权限升级或信息泄露。这会影响 Bifros
