In the Linux kernel, the following vulnerability has been resolved:
RDMA/ocrdma: Don't NULL deref uctx on errors in ocrdma_copy_pd_uresp()
Sashiko points out that pd->uctx isn't initialized until late in the
function so all these error flow references are NULL and will crash. Use
the uctx that isn't NULL.
