There is an exploit on ARM SecureBoot. The lockdown can be bypassed for loading unsigned modules. See: https://www.openwall.com/lists/oss-security/2020/06/14/1 There is a WIP patch to harden the AML/memory interaction, preventing AML code to poke around in memory: http://lists.infradead.org/pipermail/linux-arm-kernel/2020-June/580418 This final patch will need to go to supported SLE/Leap.
