CVE-2026-65584— GPU DDK - Stack Buffer Overflow via undersized UFO address array in DumpStalledContextInfo

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并运行的软件可能执行不当的 GPU 系统调用，从而引发内核中的栈溢出。该溢出发生在处理已解析的 Linux/Android 栅栏（fence）同步检查点时，而用户检查点未被纳入栈数组。成功利用此漏洞可导致内核内存损坏，并通常通过内核崩溃造成拒绝服务（DoS）状态。 该代码漏洞的本质是：由于从内部缓冲区复制了过多数据，导致在栈上向已分配数组之外的区域进行越界写入。

Vulnerability Title
GPU DDK - Stack Buffer Overflow via undersized UFO address array in DumpStalledContextInfo
Source: CVE Program / CVE List V5
Vulnerability Description
Software installed and run as a non-privileged user may conduct improper GPU system calls causing a stack overflow in the kernel. The overflow occurs when processing resolved Linux/Android fence synchronization checkpoints, while user checkpoints are excluded from the stack array. Successful exploitation can cause kernel memory corruption and typically results in a denial-of-service condition through a kernel crash. The code vulnerability is a buffer write beyond the allocated array on the stack caused by copying excessive data from an internal buffer.
