CVE-2026-81049

Local Privilege Escalation to Execute Arbitrary Code in Dell ThinOS 10

Published Sep 10, 2026 CVSS 3.1 · 4.4 Medium EPSS < 1% KEV · Not listed

Description

Dell ThinOS 10, versions prior to 2605_10.2616, contain a Missing Support for Integrity Check vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to arbitrary code execution.

Analysis

Technical impact

Dell ThinOS 10 firmware versions before 2605_10.2616 lack a critical integrity check, a weakness classified as CWE-353, which allows a high privileged attacker with local access to execute arbitrary code. This vulnerability requires local administrative rights and directly compromises the confidentiality and integrity of the device.

Affected Systems

Dell ThinOS 10 firmware versions prior to 2605_10.2616 are affected; newer firmware releases contain the fix and are not vulnerable.

Risk and Exploitability

The CVSS score of 4.4 indicates moderate overall severity, but the local arbitrary code execution capability makes the risk high in environments where local privileged access is possible. EPSS data is not available, and the vulnerability is not listed in the CISA KEV catalog, implying no known public exploits at this time. The likely attack vector is local privileged access, as local access.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
