Title
drm/amd: Guard against bad data for ATIF ACPI method
Summary
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.
```

```
It has been encountered on at least one system, so guard for it.

"value": "AV:L - The vulnerable `amdgpu_atif_call()` path is reached only from the local host \u2014 `amdgpu_acpi_detect()` at amdgpu module init and `amdgpu_acpi_event()`/`amdgpu_atif_handler()` on ACPI video notifications \u2014 with no network-facing component involved. Supplying a malformed ATIF return object is done through local software interfaces (initrd ACPI table override, acpi_configfs SSDT load, driver rebind), not physical access, so Local rather than Physical.\nAC:L - Once the ATIF method yields a non-buffer object, the missing type check is bypassed unconditionally and `info-\u003ebuffer.pointer` is dereferenced deterministically on every probe \u2014 no race, no memory-layout luck, no timing window. This matches the sibling CVE-2024-53060 in the same function, also scored AC:L.\nPR:L - The oops occurs in the amdgpu probe/ACPI-notify path on an affected system with no capability check gating it, and the resulting kernel-memory disclosure surfaces to any unprivileged local user via `/sys/class/backlight/amdgpu_bl*/brightness`. Consistent with the CNA\u0027s scoring of the directly-related CVE-2024-53060 in this same function at PR:L.\nUI:N - The faulting ATIF calls fire autonomously during driver initialization and on firmware-generated ACPI video notify events; no victim must open a file, mount anything, or interact in any way.\nS:U - The type confusion, wild read, and crash all occur inside kernel memory within the kernel\u0027s own security authority, with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - For an `ACPI_TYPE_INTEGER` return, `buffer.pointer` aliases `integer.value` exactly, so the driver reads `*(u16 *)` and then `memcpy()`s from a fully firmware-controlled arbitrary kernel address \u2014 an unbounded read primitive, not a read clamped to a few bytes. Part of that harvested memory (`ac_level`/`dc_level`) escapes the DM sanity clamp and is published to userspace as the initial backlight brightness.\nI:L - Bytes read out of bounds are written into persistent driver state (`atif-\u003ebacklight_caps`, `notification_cfg.command_code`) and drive device behavior through `backlight_device_set_brightness()`, so kernel state is modified in an attacker-influenced way. It is not High because every `memcpy()` is length-clamped by `min(sizeof(dst), size)` into a fixed-size object, giving no out-of-bounds write or control-flow hijack primitive.\nA:H - Dereferencing the aliased firmware value produces the page-fault oops shown in the commit\u0027s backtrace, and because it happens in `amdgpu_acpi_detect()` during module init the box fails to bring up graphics on every boot \u2014 a reliably repeatable kernel crash."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
