CVE-2026-68271

A flaw was found in the Linux kernel's drm/nouveau module. An issue with the error cleanup order in ucopy functions can lead to incorrect memory deallocation. This can result in a system crash, also known as a kernel oops, or a memory leak, potentially causing a denial of service.

This issue affects NVIDIA nouveau GPUs. ucopy error paths free resources in allocation order instead of reverse order, causing double-free. Systems without nouveau are not affected.
