CVE-2026-49743

CVE-2026-49743 affects GPU driver workflows where, during workload submission, the reference count of an underlying synchronisation primitive tied to an exported fence is not properly incremented. This can allow a local attacker running under a non-privileged user to destroy the exported fence an...

CVE-2025-46710

CVE-2025-46710 is tied to Imagination Technologies’ PowerVR-GPU driver. The issue arises from reusing kernel heap data after it has been freed, which can lead to kernel exceptions. Affected component: Imagination GPU Driver (PowerVR-GPU). Impact described in sources: potential kernel-level instab...

CVE-2025-58410

CVE-2025-58410 concerns Imagination Technologies PowerVR-GPU drivers. The root cause is improper handling of memory protections for a buffer resource, enabling a non-privileged process to perform improper GPU system calls that could grant write access to buffers exported as read-only via dma_buf ...

CVE-2026-22163

The CVE-2026-22163 entry describes a local, high-severity GPU driver vulnerability in Imagination Graphics DDK where malware can misuse the DDK kernel module IOCTL interface to subvert the GPU and perform writes to arbitrary physical memory pages. The root cause is unsynchronized access to a shar...
