CVE-2026-80357 describes an improper access control vulnerability in the On-Chip Debug and Test Interface of the SMCU on 17G BOSS-N1 controllers in Dell Boot Optimized Server Storage (BOSS) versions prior to 2.2.13.2038. An unauthenticated attacker with physical access could exploit this flaw to gain unauthorized access, potentially compromising the system's confidentiality, integrity, and availability. The vulnerability is categorized under CWE-1191 and carries a CVSS 3.1 score of 7.0, reflecting high severity. No known exploits in the wild have been reported, and no vendor patch links are provided in the input data.

The vulnerability allows unauthorized access through the On-Chip Debug and Test Interface due to improper access control. This could lead to a complete compromise of the affected system's confidentiality, integrity, and availability if exploited by an attacker with physical access. The high CVSS score indicates significant potential impact, but exploitation requires physical presence, limiting remote attack vectors.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch links or official fixes are provided in the input data, users should monitor Dell's official security advisories for updates. Until a fix is available, restrict physical access to affected devices and implement physical security controls to mitigate risk.
