Fix not verifiedHuawei Matebook D16(Model: CREM-WXX9, BIOS: v2.26), As the communication buffer size hasn’t been properly validated to be of the expected size, it can partially overlap with the beginning SMRAM.This can be leveraged by a malicious OS attacker to corrupt data structures stored at the beginning of SMRAM and can potentially lead to code execution in SMM.

The product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product.
An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-754: Improper Check for Unusual or Exceptional Conditions. The product does not check or incorrectly checks for unusual or exceptional conditions that are not expected to occur frequently during day to day operation of the product.
