Description Oliver Neukum 2024-02-01 11:37:57 UTC

This is from upstream:
commit f827bcdafa2a2ac21c91e47f587e8d0c76195409
Author: Rob Herring <robh@kernel.org>
Date:   Wed Jan 10 11:29:21 2024 -0600

    arm64: errata: Add Cortex-A510 speculative unprivileged load workaround
    
    Implement the workaround for ARM Cortex-A510 erratum 3117295. On an
    affected Cortex-A510 core, a speculatively executed unprivileged load
    might leak data from a privileged load via a cache side channel. The
    issue only exists for loads within a translation regime with the same
    translation (e.g. same ASID and VMID). Therefore, the issue only affects
    the return to EL0.
    
    The erratum and workaround are the same as ARM Cortex-A520 erratum
    2966298, so reuse the existing workaround.

Apparently this can be used to read memory one should not be able to read. For the exact impact and which of our kernels support the affected CPU, an ARM specialist is needed.

Comment 1 Thomas Leroy 2024-02-06 09:52:17 UTC

Thanks Oliver. This really looks like a security issue.
Can an ARM specialist double check?

Comment 2 Marcus Meissner 2024-02-07 08:57:03 UTC

Andreas or Matthias?

Comment 4 Miroslav Beneš 2024-02-07 15:11:17 UTC

commit 53960faf2b731dd2f9ed6e1334634b8ba6286850
Author: Anshuman Khandual <anshuman.khandual@arm.com>
Date:   Tue Jan 25 19:50:31 2022 +0530

    arm64: Add Cortex-A510 CPU part definition
    
    Add the CPU Partnumbers for the new Arm designs.

which got into v5.17.

commit a654a69b9f9c06b2e56387d0b99f0e3e6b0ff4ef
Author: Rob Herring <robh@kernel.org>
Date:   Thu Sep 21 14:41:51 2023 -0500

    arm64: Add Cortex-A520 CPU part definition
    
    Add the CPU Part number for the new Arm design.

which is v6.6.

So I would say A510 and SLE15-SP6 and later. Nothing for A520.

Comment 11 Ivan Ivanov 2024-02-27 06:25:24 UTC

Now chages in SLE15-SP5 also landed (572636accc429d29d5f6ef4bae6e10ee5f51fed2)
