Summary

CVE-2024-10395 is a high-severity Buffer Under-read (CWE-127) vulnerability in Zephyrproject Zephyr. Its CVSS base score is 8.6 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 23th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to RA-5 (Vulnerability Monitoring and Scanning) and SA-11 (Developer Testing and Evaluation) — see the control section below for these in your framework.

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

CVE-2024-10395 affects the Zephyr RTOS, specifically in the http_server_get_content_type_from_extension function, which lacks proper validation of the length of user input. This flaw, mapped to CWE-127, carries a CVSS v3.1 base score of 8.6 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H), indicating high severity due to its potential for significant availability disruption alongside limited confidentiality and integrity impacts.

Remote attackers require no privileges, can exploit it over the network with low complexity and no user interaction, and achieve low-level confidentiality and integrity effects while causing high availability impact, such as denial of service through improper handling of oversized input.

The Zephyr Project security advisory at https://github.com/zephyrproject-rtos/zephyr/security/advisories/GHSA-hfww-j92m-x8fv provides details on the vulnerability and mitigation guidance.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Vulnerability scanning can locate known buffer-under-read instances in deployed code.

Developer testing and evaluation (static analysis, fuzzing, bounds checkers) directly finds buffer under-read flaws before deployment.

Security engineering principles require bounds-checked memory accesses and safe pointer arithmetic that structurally stop buffer under-reads from being introduced.
