In the Linux kernel, the following vulnerability has been resolved: net: ti: icssgprueth: Fix NULL pointer dereference in pruethprobe() In the pruethprobe() function, if one of the calls to emacphyconnect() fails due to ofphyconnect() returning NULL, then the subsequent call to phyattachedinfo() will dereference a NULL pointer. Check the return code of emacphy_connect and fail cleanly if there is an error.
