CVE-2026-93037
Published Sep 17, 2026
Description
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.

What is CVE-2026-93037? +
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.
