Doc Text:
A flaw was found in the Linux kernel's NVMe (Non-Volatile Memory Express) over Fabrics RDMA (Remote Direct Memory Access) target subsystem. When pending disconnecting queues exceed the backlog threshold, the connection handler fails to release newly allocated queue structures and associated network resources. A remote attacker could exploit this issue by initiating connection requests during backlog conditions, leading to resource leaks and a potential Denial of Service (DoS) through memory exhaustion.

Description OSIDB Bzimport 2026-09-25 11:36:49 UTC
In the Linux kernel, the following vulnerability has been resolved:

nvmet-rdma: fix queue leak when connect backlog is exceeded

When pending disconnecting queues exceed the backlog limit, the
connect path only drops the device reference and leaks the newly
allocated queue and its IB resources.
