Description Summary:
A race condition in the Linux kernel's RDMA/rxe component within the QP timer handler can lead to system instability.
Executive Summary:
A race condition in the Linux RDMA subsystem could lead to unpredictable system behavior or denial-of-service.
Vulnerability Details
CVE-ID: CVE-2026-45910
Affected Software: Linux Kernel
Affected Versions: See vendor advisory for specific affected versions
Vulnerability: The vulnerability is a race condition occurring within the QP (Queue Pair) timer handlers in the
rdma_rxedriver. This can be triggered by specific timing sequences during RDMA operations, potentially causing internal warnings or kernel panics.Business Impact
This flaw poses a risk to service availability, particularly for high-throughput network environments relying on RDMA. With a CVSS score of 7.8, it is considered high-priority for data centers.
Remediation Plan
Immediate Action: Update the kernel to the latest version to include the fix for the race condition in the RDMA/rxe driver.
Proactive Monitoring: Monitor system logs for warnings related to
rxe_taskor other RDMA-related kernel warnings.Compensating Controls: If immediate patching is not possible, avoid using the
rdma_rxesoftware implementation in production environments.Exploitation Status
Public Exploit Available: false
Analyst Notes: As of June 1, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.
Analyst Recommendation
We recommend applying the kernel patch immediately. Race conditions in kernel drivers are often difficult to debug and can lead to non-deterministic system failures; patching is the only reliable mitigation.
