The libspdm submodule was pinned at 3.7.0 (2025-04-03), three releases behind
upstream 3.8.2 (2026-04-03). libspdm processes untrusted responder (device)
data in the SPDM device attestation path, so tracking upstream keeps that
parsing current with fixes and hardening.
Two responder-side advisories were resolved between 3.7.0 and 3.8.2:
- GHSA-j54w-759w-xj3m: out-of-bounds write in GET_CSR handling.
- GHSA-m4wc-xmvg-369f: integer overflow / out-of-bounds read in
GET_MEASUREMENT_EXTENSION_LOG handling.
Both are responder-side. edk2 links SpdmRequesterLib (it acts as the SPDM
Requester that verifies an untrusted device Responder), so these responder
handlers are not built into edk2 images; this update is defense-in-depth
rather than a fix for a path reachable in edk2 today.
The libspdm sources referenced by the SpdmLib INFs are unchanged in 3.8.2
(the only additions are the optional ENDPOINT_INFO capability sources, which
edk2 does not enable), so no INF change is required.
