Description

In the Linux kernel, the following vulnerability has been resolved: drm/amd: Guard against bad data for ATIF ACPI method If a BIOS provides bad data in response to an ATIF method call this causes a NULL pointer dereference in the caller. ``` ? show_regs (arch/x86/kernel/dumpstack.c:478 (discriminator 1)) ? __die (arch/x86/kernel/dumpstack.c:423 arch/x86/kernel/dumpstack.c:434) ? page_fault_oops (arch/x86/mm/fault.c:544 (discriminator 2) arch/x86/mm/fault.c:705 (discriminator 2)) ? do_user_addr_fault (arch/x86/mm/fault.c:440 (discriminator 1) arch/x86/mm/fault.c:1232 (discriminator 1)) ? acpi_ut_update_object_reference (drivers/acpi/acpica/utdelete.c:642) ? exc_page_fault (arch/x86/mm/fault.c:1542) ? asm_exc_page_fault (./arch/x86/include/asm/idtentry.h:623) ? amdgpu_atif_query_backlight_caps.constprop.0 (drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c:387 (discriminator 2)) amdgpu ? amdgpu_atif_query_backlight_caps.constprop.0 (drivers/gpu/drm/amd/amdgpu/amdgpu_acpi.c:386 (discriminator 1)) amdgpu ``` It has been encountered on at least one system, so guard for it.
