Summary

CVE-2024-20082 is a critical-severity Improper Restriction of Operations within the Bounds of a Memory Buffer (CWE-119) vulnerability in Mediatek Nr15. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Process Injection (T1055); ranked in the top 31% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-8 (Security and Privacy Engineering Principles) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

In Modem software, a missing bounds check can trigger memory corruption, as described under CVE-2024-20082. The flaw is tracked by MediaTek as Issue ID MSV-1529 with Patch ID MOLY01182594 and carries a CVSS 3.1 base score of 9.8. It affects the modem component and is classified under CWE-119.

An unauthenticated attacker can send specially crafted network traffic to trigger the flaw, obtaining remote code execution without user interaction or additional privileges. The attack surface is exposed over the network because the modem processes untrusted data directly.

MediaTek’s August 2024 product security bulletin lists the issue and directs users to apply the referenced patch for affected modem firmware versions.

EPSS for the CVE rose from a low baseline after disclosure to a peak of 0.1200 on 2026-01-13 before receding to the current value of 0.0664, indicating a period of increased exploitation interest following public release.

Mitigating Controls (NIST 800-53 r5) AI

Secure engineering principles require memory-safe design and coding that structurally avoids buffer-boundary violations.

Input validation directly enforces bounds checking that stops out-of-bounds reads/writes from being introduced or reached.

Memory protection restricts exploitation impact of buffer overflows without eliminating the underlying coding flaw.
