When handling local connections, the system miscalculates the required communication paths, allocating internal work queues that are not properly freed during connection teardown. A local user can exploit this vulnerability by repeatedly opening and closing local connections, triggering a kernel memory leak that can lead to resource exhaustion and a Denial of Service (DoS).\n\n## Vendor advisories\n\n- **Red Hat VEX** · Low · affected: Red Hat Enterprise Linux 6 · no fix planned: Red Hat Enterprise Linux 6 · updated 2026-10-20 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-98560.json)\n\n**kernel: net/rds: size a connection's path set by the transport it ends up with** — rated Low by Red Hat.
