Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: arm64: dts: qcom: x1e80100: Add GPU cooling Unlike the CPU, the GPU does not throttle its speed automatically when it reaches high temperatures. With certain high GPU loads it is possible to reach the critical hardware shutdown temperature of 120°C, endangering the hardware and making it impossible to run certain applications. Set up GPU cooling similar to the ACPI tables, by throttling the GPU speed when reaching 95°C and polling every 200ms.

Recommended fix High confidence

Linux kernel 6.12.34, 6.14.10, or 6.15.1 (or later stable releases)

  1. Identify the current running kernel version using 'uname -r'
  2. Download and install a fixed kernel version: upgrade to Linux kernel 6.12.34 or later, 6.14.10 or later, or 6.15.1 or later
  3. For distribution-specific systems, use the distro's package manager to update (e.g., apt-get update && apt-get upgrade on Debian/Ubuntu, dnf update on Fedora, or pacman -Syu on Arch)
  4. Reboot the system to load the new kernel
  5. Verify the new kernel is running with 'uname -r'
Caveat Kernel upgrades may require reinstalling proprietary drivers (e.g., NVIDIA GPU drivers) and could introduce compatibility issues with custom kernel modules
