    CVE-2025-7029 (GCVE-0-2025-7029)

    Vulnerability from nvd – Published: 2025-07-11 15:22 – Updated: 2026-02-26 17:50
    VLAI
    Title
    SMM Arbitrary Write via Unchecked OcHeader Buffer in Platform Configuration Handler
    Summary
    A vulnerability in the Software SMI handler (SwSmiInputValue 0xB2) allows a local attacker to control the RBX register, which is used to derive pointers (OcHeader, OcData) passed into power and thermal configuration logic. These buffers are not validated before performing multiple structured memory writes based on OcSetup NVRAM values, enabling arbitrary SMRAM corruption and potential SMM privilege escalation.
