CVE-2026-64281

A flaw was found in the Linux kernel's svcrdma component. During transport teardown, threads waiting in svc_rdma_sq_wait() can hang indefinitely in an uninterruptible state. This occurs because these threads are not explicitly woken up when the transport closes, leading to them continuously holding references to svc_xprt. Consequently, this can block the svc_rdma_free() function, resulting in a denial of service (DoS) condition.
