Microsoft updates WSL2 kernel to Linux 6.18.54.1 with DXGKRNL fence sharing
unixterminal · x · 2026-10-08
Microsoft released the linux-msft-wsl-6.18.54.1 WSL2 kernel, tracking upstream Linux 6.18.54 LTS for bug and security fixes. Key change: native fence sharing in the DXGKRNL DirectX driver, using the global vmbus channel and returning the host sync object via an explicit out-parameter to fix handle handling and refcounting. It follows WSL 3.0.2, which added support for very large servers and experimental sparse VHD storage.
