    Added Description In the Linux kernel, the following vulnerability has been resolved:

    firmware: qcom: uefisecapp: fix efivars registration race

    Since the conversion to using the TZ allocator, the efivars service is
    registered before the memory pool has been allocated, something which
    can lead to a NULL-pointer dereference in case of a racing EFI variable
    access.

    Make sure that all resources have been set up before registering the
    efivars.
