CVE-2011-5174: Buffer overflow in Intel Trusted Execution Technology (TXT) SINIT Authenticated Code Modules (ACM) in Intel...

Buffer overflow in Intel Trusted Execution Technology (TXT) SINIT Authenticated Code Modules (ACM) in Intel Q67 Express, C202, C204, C206 Chipsets, and Mobile Intel QM67, and QS67 Chipset before 2nd_gen_i5_i7_SINIT_51.BIN Express; Intel Q57, 3450 Chipsets and Mobile Intel QM57 and QS57 Express Chipset before i5_i7_DUAL_SINIT_51.BIN and i7_QUAD_SINIT_51.BIN; Mobile Intel GM45, GS45, and PM45 Express Chipset before GM45_GS45_PM45_SINIT_51.BIN; Intel Q35 Express Chipsets before Q35_SINIT_51.BIN; and Intel 5520, 5500, X58, and 7500 Chipsets before SINIT ACM 1.1 allows local users to bypass the Trusted Execution Technology protection mechanism and perform other unspecified SINIT ACM functions via unspecified vectors.

Security readout for executives and security teams

CVE-2011-5174 is a buffer overflow in Intel TXT SINIT modules used by older Intel chipsets. A local user could bypass TXT protections, weakening systems that depend on measured launch or trusted execution. Business urgency is highest where legacy hardware still relies on Intel TXT for high-assurance workloads. Exposure is limited to older Intel platforms using TXT with vulnerable SINIT ACM binaries. Systems not using Intel TXT may have lower practical exposure, but the source bundle does not confirm non-exploitability when TXT is disabled. Treat as a targeted legacy-platform risk. Remediate promptly where Intel TXT is part of security assurance, compliance, or sensitive workload isolation. For general legacy endpoints without TXT reliance, handle through normal firmware lifecycle review. Mitigation focus: Inventory legacy Intel systems using TXT and affected chipsets.; Compare SINIT ACM binaries against the fixed versions named in the CVE.; Apply Intel or platform-vendor guidance for updated SINIT ACM/firmware..
