Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Implements memory protection mechanisms such as DEP, ASLR, and stack canaries that directly prevent exploitation of out-of-bounds write vulnerabilities like CVE-2024-57961.
Requires timely identification, reporting, and patching of flaws such as the out-of-bounds write in the emcom module, as recommended in Huawei's security bulletin.
Validates information inputs to the emcom module to block malformed data that could trigger the out-of-bounds write and lead to confidentiality or availability impacts.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Local out-of-bounds write with no privileges required directly enables exploitation for privilege escalation to access sensitive data.
NVD Description
Out-of-bounds write vulnerability in the emcom module Impact: Successful exploitation of this vulnerability may cause features to perform abnormally.
Deeper analysisAI
CVE-2024-57961 is an out-of-bounds write vulnerability (CWE-787) in the emcom module. It was published on 2025-02-06 and carries a CVSS v3.1 base score of 6.8 (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:L), rated as medium severity. The vulnerability affects Huawei consumer products, as detailed in the vendor's security bulletin.
A local attacker requires no privileges, low attack complexity, and no user interaction to exploit this vulnerability. Successful exploitation can result in high confidentiality impact, potentially allowing unauthorized access to sensitive data, alongside low availability impact that may cause affected features to perform abnormally.
