CVE-2026-89597

A flaw in the Linux kernel's uvesafb fbdev driver leaves the v86d connector callback registered when platform_driver_register() fails during initialization, because the error path returns without unregistering the callback. This results in a resource leak that, per Red Hat, may lead to system ins...
