CVE-2026-49744
GPU DDK - Unchecked ui32TracePointer in rgxfw_log_ex()
Description
Kernel software installed and running inside a Guest VM may post improper commands to the GPU Firmware to trigger a write of data outside the Guest's virtualised GPU memory. Out of bounds accesses triggered by malware introduced to a Guest KMD could allow privilege escalation which escapes virtualization boundaries.
