CVE-2026-68232

A flaw was found in the Linux kernel's drm/gpusvm component. When the kvmalloc_array() function fails within drm_gpusvm_range_evict(), a previously acquired memory management (MM) reference is not properly released. This oversight leads to a reference leak, which can result in resource exhaustion and a Denial of Service (DoS) condition for the system.

This issue affects systems using the drm/gpusvm GPU shared virtual memory interface. If kvmalloc_array() fails in drm_gpusvm_range_evict(), an acquired MM reference is not dropped, leaking address-space references. Systems without gpusvm-capable GPU drivers are not affected.
