CVE-2026-80888

A flaw was found in the drm/vmwgfx component of the Linux kernel. An unprivileged client can exploit this vulnerability by passing a specially crafted file descriptor fd to the DRMVMWGBSURFACEREF or DRMVMWGBSURFACEREFEXT paths. This can lead to a dmabuf reference leak, causing resource exhaustion...
