Details

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

xprtrdma: fix pointer derefs in error cases of rpcrdmaepcreate

If there are failures then we must not leave the non-NULL pointers with the error value, otherwise rpcrdma_ep_destroy gets confused and tries free them, resulting in an Oops.
