Vulnerability from variot - Updated: 2025-04-11 23:16

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. Mobile Intel Qm67 Chipset is prone to a local security vulnerability. Intel Trusted Execution Technology (TXT, Intel Trusted Execution Technology) is a hardware extension technology in the Intel Core 2 Duo processor, mainly used to protect data in a virtualized computing environment from spyware Attacks, virus intrusion and other threats. ----------------------------------------------------------------------
