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

    drm/amd/display: Fix invalid context error in dml helper

    [Why]
    “BUG: sleeping function called from invalid context” error.
    after:
    “drm/amd/display: Protect FPU in dml2_validate()/dml21_validate()”

    The populate_dml_plane_cfg_from_plane_state() uses the GFP_KERNEL flag
    for memory allocation, which shouldn’t be used in atomic contexts.

    The allocation is needed only for using another helper function
    get_scaler_data_for_plane().

    [How]
    Modify helpers to pass a pointer to scaler_data within existing context,
    eliminating the need for dynamic memory allocation/deallocation
    and copying.
