Description

This security bulletin contains information about 1 vulnerability.


1) Deadlock (CVE-ID: CVE-2026-31565)

CWE-ID: CWE-833 - Deadlock

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a deadlock condition in the irdma RDMA subsystem when executing a netdev reset while RDMA applications have active connections. A local user can trigger a netdev reset during active RDMA connections to cause a denial of service.

The issue occurs during device removal in iWARP mode when client cleanup creates a circular dependency involving QP reference counting.
