A flaw was found in the Linux kernel's Non-Transparent Bridge (NTB) transport module. When the NTB transport attempts to transmit packets while the Queue Pair (QP) link is down, the system incorrectly reports a successful transmission without properly consuming the packet. This oversight leads to a memory leak, where system memory is not released, potentially affecting system stability and performance over an extended period.
kernel: NTB: ntb_transport: Fail TX enqueue when the QP link is down — rated Low by Red Hat. Released 2026-09-11, updated 2026-09-14.
