CVE-2024-20149 is a vulnerability in the Modem component stemming from improper input validation (CWE-1284), which can trigger a system crash. It affects MediaTek products, as detailed in their product security bulletin.

The vulnerability enables a remote denial-of-service attack, exploitable by any unauthenticated attacker over the network with low attack complexity and no user interaction required. Successful exploitation results in high-impact availability disruption (A:H) without affecting confidentiality or integrity, earning a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

MediaTek advisories recommend applying patches MOLY01231341, MOLY01263331, or MOLY01233835 to mitigate the issue (tracked as MSV-2165). Full details are available in the January 2025 product security bulletin at https://corp.mediatek.com/product-security-bulletin/January-2025.

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

SI-10 requires validity checks on information inputs, directly stopping acceptance of malformed quantities before they can be used.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper quantity/length validation in input handling.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development can detect missing quantity validation but does not itself implement the control.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation for quantity fields, directly preventing CWE-1284.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for validation of size/length inputs, mitigating CWE-1284.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles encourage robust input handling but do not specifically address quantity validation.

A.8.28 Secure coding partial match
prevents

Secure coding standards require explicit checks on numeric quantity inputs, fully addressing CWE-1284.
