CVE-2011-5174: 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.
The exploitability of CVE-2011-5174 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The vulnerability CVE-2011-5174 is highly exploitable since it requires low complexity and no authentication.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2011-5174, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2011-5174, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.042% (probability of exploit)
EPSS Percentile: 5.07%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 94.93% of others.
