Summary
In the Linux kernel, the following vulnerability has been resolved: drm/vkms: Fix use after free and double free on init error If the driver initialization fails, the vkms_exit() function might access an uninitialized or freed default_config pointer and it might double free it. Fix both possible errors by initializing default_config only when the driver initialization succeeded.
