Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly enforces memory protection mechanisms to mitigate improper memory address protection vulnerabilities like CVE-2024-56438 in the HUKS module.
Provides for timely remediation of the specific HUKS memory flaw through patching as referenced in the Huawei security bulletin.
Isolates HUKS module processes to prevent memory corruption from propagating and causing broader system availability impact with changed scope.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Local memory protection flaw (CWE-119) with high-priv access yields availability impact via system/application exploitation, directly enabling endpoint DoS.
NVD Description
Vulnerability of improper memory address protection in the HUKS module Impact: Successful exploitation of this vulnerability may affect availability.
Deeper analysisAI
CVE-2024-56438 is a vulnerability involving improper memory address protection in the HUKS module. It is classified under CWE-119 and has a CVSS v3.1 base score of 6.0 (AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H). The vulnerability was published on 2025-01-08.
Exploitation requires local access (AV:L) with high privileges (PR:H), low attack complexity (AC:L), and no user interaction (UI:N). A successful attack can achieve high impact on availability (A:H) with a changed scope (S:C), potentially disrupting system services.
