CVE-2025-37764

Local service interruption via firmware memory leaks

Published May 1, 2025 · Updated May 11, 2026

Memory leaks in the powervr driver in affected Linux 6.8 through 6.15-rc1 builds allow local users to interrupt service. In drivers/gpu/drm/imagination/pvr_fw.c, firmware image results remain allocated during module unload, and firmware buffers and GEM objects are not released after image-processing failures. Reachability requires local low-privileged access and execution of the powervr firmware load or unload paths; the bounded consequence is memory exhaustion and service interruption, not data disclosure or modification.
