Description
A vulnerability in the Linux kernel's nvmet-rdma subsystem causes a resource leak when the connect backlog limit is exceeded. Specifically, when pending disconnecting queues surpass the backlog limit, the connect path drops the device reference but leaks the newly allocated queue and its InfiniBand (IB) resources. This issue has been fixed in Linux kernel versions 6.12.111, 6.18.53, 7.2, and corresponding commits.
