Description
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.
