NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek package and not the kernel-uek package as distributed by Oracle. See How to fix? for Oracle:7 relevant fixed versions and status.

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.
