Description
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.
