Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A race condition in the Linux kernel's cros ec uart probe() function can trigger a NULL pointer dereference. This occurs when devm serdev device open() is called before serdev device set client ops(), setting SERPORT ACTIVE before serdev->ops is set. The serdev controller receive buf() function assumes that if SERPORT ACTIVE is set and serdev exists, serdev->ops will also exist, which is not the case. This can lead to a kernel NULL pointer dereference.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
