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. Found by Linux Verification Center (linuxtesting.org) with SVACE.
