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 (NIST 800-53 r5) AI

SI-2 Flaw Remediation good match
prevent

Directly mitigates the out-of-bounds write vulnerability by requiring timely remediation through patching to Intel QuickAssist Technology software version 2.2.0 or later.

SI-16 Memory Protection good match
prevent

Implements memory protection techniques such as address space layout randomization and data execution prevention to block exploitation of the out-of-bounds write for privilege escalation.

AC-6 Least Privilege partial match
prevent

Limits the privileges of the authenticated low-privilege user, reducing the attack surface and potential impact of successful local exploitation.
