Summary
CVE-2024-20150 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Mediatek Lr12A. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 45% of CVEs by exploit likelihood; 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 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 components from MediaTek, a logic error can trigger a system crash, resulting in remote denial of service. The flaw is tracked as CVE-2024-20150 with a CVSS score of 7.5 and is associated with CWE-502; it requires no user interaction or elevated privileges for exploitation and is addressed via patch ID MOLY01412526.
An unauthenticated remote attacker can send crafted input over the network to induce the crash, disrupting service availability on affected devices without gaining code execution or accessing sensitive data.
The MediaTek January 2025 security bulletin lists the corresponding Issue ID MSV-2018 and directs vendors to apply the referenced patch for remediation.
EPSS scores remain low, with a current value of 0.0736 and a peak of 0.0934, indicating limited observed exploitation interest to date.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
