CVE-2026-65584: Imagination GPU DDK stack overflow in fence synchronization checkpoint processing

CVE-2026-65584 · Severity: info · Published 2026-10-30

Imagination Technologies GPU driver allows unprivileged users to trigger a kernel stack overflow through improper GPU system calls when processing Linux/Android fence synchronization checkpoints. Successful exploitation can corrupt kernel memory and crash the system, causing a denial of service.

Technologies: Imagination Technologies GPU DDK. Vendors: Imagination Technologies.

Technical details

A buffer write vulnerability exists where excessive data from an internal buffer is copied beyond the allocated stack array during processing of resolved fence synchronization checkpoints (Linux/Android fences are affected; user checkpoints are excluded). An unprivileged attacker can conduct improper GPU system calls to trigger the overflow, leading to kernel memory corruption and typically a denial-of-service condition via kernel crash.
