Summary

CVE-2024-20148 is a critical-severity Out-of-bounds Write (CWE-787) vulnerability in Linuxfoundation Yocto. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 18th 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.

CVE-2024-20148 is an out-of-bounds write vulnerability in the WLAN Station (STA) firmware due to improper input validation, tracked under CWE-787. It affects the WLAN STA firmware component, as detailed in MediaTek's product security bulletin. The issue carries a CVSS v3.1 base score of 9.8 (Critical), with vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating high confidentiality, integrity, and availability impacts.

The vulnerability enables remote proximal or adjacent code execution without requiring additional privileges or user interaction. Attackers in network proximity can exploit it over the air via crafted wireless packets, potentially compromising the affected device at the firmware level.

MediaTek's January 2025 product security bulletin provides mitigation details, including Patch ID WCNCR00389045 and ALPS09136494, associated with Issue ID MSV-1796. Security practitioners should apply these patches to vulnerable WLAN STA firmware implementations.

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.
