CVE-2024-26912

Local service interruption via unreleased DMA buffers

Published Apr 17, 2024 · Updated May 11, 2026

Memory leakage in the Linux kernel 6.7 through 6.7.5 allows local users to interrupt service through the nouveau GSP-RM driver. The nvkm_gsp_mem lifecycle fails to free several DMA allocations after initialization or during driver teardown. Low-privileged local access and an active nouveau GSP-RM configuration are required; sustained triggering can exhaust memory and crash or hang the host.
