CVE-2026-93037— RDMA/hfi1: Propagate sdma_txinit_ahg() errors

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已解决以下漏洞： RDMA/hfi1：传播 sdma_txinit_ahg() 的错误 set_txreq_header_ahg() 函数忽略了 sdma_txinit_ahg() 的返回值。 如果 sdma_txinit_ahg() 调用失败，它会在初始化 tx->txreq 之前直接返回。然而，set_txreq_header_ahg() 忽略了该错误，并返回 AHG（Address Handle Group，地址句柄组）的变更计数，导致调用方误以为初始化已成功，从而继续处理该请求。 修

Vulnerability Title
RDMA/hfi1: Propagate sdma_txinit_ahg() errors
Source: CVE Program / CVE List V5
Vulnerability 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.
