  96. Upgrade

    Upgrade Linux kernel (Hyper-V hv_utils / hv_vmbus) to a version that resolves this vulnerability.

    Patch Drivers: hv: util: Avoid accessing a ringbuffer not initialized yet
  97. Configuration

    In util_probe(), reorder the steps so the char dev entry used by the KVP (and VSS) daemon is not created until after vmbus_open() has completed; this avoids invoking the KVP/VSS channel callback before the VMBus channel ringbuffer is initialized (prevents NULL pointer dereference in hv_pkt_iter_first).

    Hyper-V hv_utils util_probe() / VMBus char dev creation path Reorder initialization steps so the KVP/VSS char dev entry is created only after vmbus_open() completes = Create /dev/vmbus/hv_kvp (KVP daemon char dev entry used by kvp_on_msg()) only after vmbus_open() has completed and after ringbuffer initialization (after first hv_ringbuffer_init)
