GPU Cooling Implementation in Linux Kernel for Qualcomm Devices

CVE-2025-38093

What is CVE-2025-38093?

A vulnerability has been identified in the Linux kernel related to inadequate cooling mechanisms for GPUs in Qualcomm devices. Unlike CPUs, which commonly utilize thermal throttling at high temperatures, GPUs can reach critical shutdown temperatures of 120°C under heavy load without regulation. This vulnerability may result in hardware damage and application failures. The fix involves implementing GPU cooling similar to existing ACPI table configurations, enforcing speed throttling at temperatures exceeding 95°C and regularly polling the temperature every 200ms to prevent overheating.
