Published: 25 February 2025
Summary
CVE-2025-1674 is a high-severity Out-of-bounds Read (CWE-125) vulnerability in Zephyrproject Zephyr. Its CVSS base score is 8.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 46.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2025-1674 is a vulnerability in the Zephyr RTOS stemming from a lack of input validation, which enables out-of-bounds reads triggered by malicious or malformed packets. Classified under CWE-125 (Out-of-bounds Read), it carries a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:H) and was published on 2025-02-25T08:15:29.887.
Remote, unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. Exploitation results in limited confidentiality impact, such as partial information disclosure, alongside high availability impact, potentially causing denial-of-service conditions through system crashes induced by the out-of-bounds reads.
The Zephyr project has published a security advisory at https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-x975-8pgf-qh66, which security practitioners should review for details on mitigation strategies and available patches.
