From 477bc3068fc3777b9d8ffd79e265b0dfdf2d3a6b Mon Sep 17 00:00:00 2001 From: Junrui Luo Date: Tue, 15 Sep 2026 15:39:11 +0800 Subject: drm/virtio: fix object leak in virtio_gpu_resource_create_ioctl() virtio_gpu_resource_create_ioctl() calls drm_gem_object_release() on the drm_gem_handle_create() error path instead of dropping the reference it owns, so obj->funcs->free() never runs and the virtio_gpu_object, its pages and sg table, the resource id and the host-side resource are leaked. Use drm_gem_object_put() instead.
