Details

In the Linux kernel, the following vulnerability has been resolved:

can: afcan: fix NULL pointer dereference in canrcv_filter

Analogue to commit 8aa59e355949 ("can: afcan: fix NULL pointer dereference in canrxregister()") we need to check for a missing initialization of mlpriv in the receive path of CAN frames.

Since commit 4e096a18867a ("net: introduce CAN specific pointer in the struct netdevice") the check for dev->type to be ARPHRDCAN is not sufficient anymore since bonding or tun netdevices claim to be CAN devices but do not initialize ml_priv accordingly.
