CVE-2025-22097

Estado: ModificadaAlta (7.8)—

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.
