CVE-2025-66369: n/a
CVE-2025-66369 is a high-severity vulnerability affecting multiple Samsung Mobile Processor, Wearable Processor, and Modem Exynos models. It involves incorrect handling of 5G NR NAS registration accept messages, which can lead to a denial of service (DoS) condition. The vulnerability does not impact confidentiality or integrity but causes service disruption. There is no confirmed patch or official remediation available at this time. No known exploits are reported in the wild. The affected product versions are not specified. The vulnerability is categorized under CWE-770 (Allocation of Resources Without Limits or Throttling).
AI Analysis
Technical Summary
This vulnerability in Samsung Exynos processors and modems arises from improper processing of 5G NR NAS registration accept messages, resulting in a denial of service. It affects a broad range of Exynos chipsets including mobile, wearable, and modem variants. The CVSS v3.1 base score is 7.5, indicating high severity due to network attack vector, low attack complexity, no privileges or user interaction required, and impact limited to availability. The issue is documented as CWE-770, reflecting resource management flaws. No patch or remediation level has been published, and no exploits are currently known.
Potential Impact
Successful exploitation causes denial of service, disrupting availability of affected Samsung Exynos processors and modems during 5G NR NAS registration. There is no impact on confidentiality or integrity. The disruption could affect device connectivity or functionality relying on these chipsets. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or remediation level is provided, monitor Samsung's security advisories for updates. Until a patch is available, consider limiting exposure to untrusted 5G network messages if feasible.
