CVE-2026-89531

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the svcrdma component where the handle connect req() function fails to take action when svc rdma create xprt() cannot allocate a new transport. Because the Connection Manager (CM) core returns 0 for CONNECT REQUEST events, the rdma cm id is not destroyed. This leads to a leak of one rdma cm id for each allocation failure during memory pressure, a condition that can be amplified by a remote peer initiating multiple connection attempts.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
