CVE-2026-98152 · Severity: info · Published 2026-09-25

The Linux kernel's NVMe over RDMA target module contains a resource leak in its connection handling path. When the backlog of pending disconnections exceeds a limit, newly allocated queue structures and associated InfiniBand resources are not properly freed, leading to memory exhaustion over time on systems hosting NVMe storage targets.

## Technical details

The nvmet-rdma driver fails to deallocate queue and IB resources in the error path when pending disconnecting queues exceed the backlog limit; it only drops the device reference. A remote attacker with network access to the RDMA service can repeatedly trigger connection attempts that exceed the backlog, causing accumulated resource leaks and eventual denial of service.

## Affected products

- Linux Linux multiple kernel versions across 2.6.x through 6.x
