CVE-2024-27411

Rendering freeze via premature DMA buffer deallocation

Published May 17, 2024 · Updated Aug 5, 2026

Availability flaw in the nouveau GSP driver in Linux 6.7.6 through 6.7.8 allows local users to freeze system-wide rendering during resume. The r535 GSP post-initialization path frees the RMARGS and WPR metadata DMA buffers even though later suspend and resume handling still requires them. On multi-GPU systems using nouveau GSP runtime power management, an unprivileged process with render-node access can induce the suspend path and leave rendering frozen.
