CVE-2024-26698 is a race condition in the Linux kernel Hyper-V network driver, hv_netvsc, between netvsc_probe() and netvsc_remove(). During device removal, the driver could call napi_disable() on subchannel NAPI structures that had been added but not enabled because asynchronous subchannel setup had not yet run. The NAPI state prevents scheduling until napi_enable() clears the scheduling-state bit; consequently, calling napi_disable() on such a non-enabled structure can block indefinitely. The upstream fix avoids calling napi_disable() for NAPI structures that were not enabled, while retaining netif_napi_del() cleanup.
