Summary

CVE-2024-31858 is a high-severity Out-of-bounds Write (CWE-787) vulnerability in Intel Quickassist Technology. Its CVSS base score is 7.3 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 15th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-31858 is an out-of-bounds write vulnerability (CWE-787) in Intel QuickAssist Technology software versions prior to 2.2.0. This flaw affects the specified software component, which is used for hardware-accelerated cryptographic and data compression/compression tasks. The vulnerability carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential impact on confidentiality, integrity, and availability.

An authenticated user with low privileges can exploit this vulnerability via local access. The attack requires low complexity and no user interaction, allowing the attacker to potentially escalate privileges on the affected system.

Intel's security advisory (INTEL-SA-01124) details the issue and mitigation steps, available at https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01124.html. Updating to Intel QuickAssist Technology software version 2.2.0 or later addresses the vulnerability.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation (including fuzzing and bounds checks) finds out-of-bounds write flaws before deployment.

SA-15 Development Process, Standards, and Tools partial match

Requiring documented secure-development standards and tools can mandate bounds-checked coding practices that avoid the weakness.

SI-10 Information Input Validation partial match

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

SI-16 Memory Protection partial match

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.
