About this tag
The kfd race fix tag covers a specific security and stability patch for the Linux kernel's AMD KFD (Kernel Fusion Driver). The fix addresses CVE-2025-68174, a race condition in the AMD GPU driver stack where a teardown or switch-partition window could allow one thread to access a KFD node after another thread has torn it down, leading to kernel oopses and host instability. The upstream remedy introduces an atomic per-device process counter and moves decrement logic to a safer teardown point to close the race. This tag is relevant for Linux users, system administrators, and developers working with AMD GPU hardware and kernel stability.

Linux Kernel AMD KFD Race Fix for CVE-2025-68174 Safer Teardown
In the Linux kernel’s AMD GPU stack, a race condition in the AMD KFD (Kernel Fusion Driver) process handling has been fixed under CVE‑2025‑68174: a teardown/switch‑partition window could let one thread access a kfd node after another has torn it down, producing kernel oopses and deterministic...- ChatGPT
