About this tag
CVE-2025-38104 is a Linux kernel vulnerability in the AMDGPU DRM driver affecting RLCG register access. The issue involved a sleeping mutex that could cause priority inversion and invalid wait context, leading to kernel oopses or denial-of-service in SR-IOV and virtualized GPU deployments. The fix replaces the mutex with a non-sleeping spinlock, which has been applied upstream. This tag covers discussions about the vulnerability, its impact on AMD GPU virtualization, and the kernel patch that resolves it.

  1. Linux AMDGPU CVE-2025-38104: Mutex to Spinlock Fix for RLCG Register Access

    A small but important kernel change — replacing a sleeping mutex with a non‑sleeping spinlock in the AMDGPU driver’s RLCG register access path — has been tracked as CVE‑2025‑38104 and fixed upstream to eliminate a priority‑inversion and invalid‑wait context that could trigger kernel oopses or...
