CVE-2024-20082
Published: 14 August 2024
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, ranked in the top 8.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ongoing control assessments and code testing (static/dynamic analysis, fuzzing) surface memory buffer restriction failures, which are then remediated before release.
Managed runtimes used by platform-independent applications (e.g., JVM, CLR) enforce memory safety, preventing most buffer overflows that require direct memory manipulation.
Memory protections (e.g., W^X, ASLR) make exploitation of buffer-boundary violations far harder to turn into code execution.
Detects exploitation attempts that produce memory corruption, crashes, or anomalous behavior.
