NVD

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.
