27 Trusted Firmware (TF) unconditionally assign this bit to ``0`` in the early
32 normal world attacker to induce a panic in the secure world.
34 The ``MDCR_EL3.SDD`` bit should be assigned to ``1`` to disable debug exceptions
37 Earlier versions of TF (prior to `commit 495f3d3`_) did not assign this bit.
41 A similar issue applies to the ``MDCR_EL3.SPD32`` bits, which control AArch32
42 secure self-hosted invasive debug enablement. TF assigns these bits to ``00``
46 which point the device is vulnerable to other, more serious attacks anyway.
49 ``MDCR_EL3.SPD32`` bits should be assigned to ``10`` to disable debug exceptions
52 Finally, this also issue applies to AArch32 platforms that use the TF SP_MIN
54 macro. Here the affected bits are ``SDCR.SPD``, which should also be assigned to
