CVE-2026-64281

A flaw was found in the Linux kernel's svcrdma component. During transport teardown, threads waiting in svcrdmasqwait 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...
