Description

RDMA/cxgb4: Added NULL check for lookup_atid

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

RDMA/cxgb4: Added NULL check for lookup_atid

The lookup_atid() function can return NULL if the ATID is

invalid or does not exist in the identifier table, which

could lead to dereferencing a null pointer without a

check in the act_establish() and act_open_rpl() functions.

Add a NULL check to prevent null pointer dereferencing.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
