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

RDMA/hfi1: Propagate sdma_txinit_ahg() errors

set_txreq_header_ahg() ignores the return value of sdma_txinit_ahg().

If sdma_txinit_ahg() fails, it returns before initializing tx->txreq.
However, set_txreq_header_ahg() ignores the error and returns the AHG
change count, causing the caller to continue processing the request as
though initialization had succeeded.

Propagate sdma_txinit_ahg() failures to the caller and abort request
processing when initialization fails.
