Descriptions
In the Linux kernel, the following vulnerability has been resolved: can: etas_es58x: fix potential NULL pointer dereference on udev->serial The driver assumed that es58x_dev->udev->serial could never be NULL.
While this is true on commercially available devices, an attacker
could spoof the device identity providing a NULL USB serial number.
That would trigger a NULL pointer dereference. Add a check on es58x_dev->udev->serial before accessing it.
