DescriptionCVE.org

Dell Command Update (DCU), versions prior to 5.7.1, contain an Improper Link Resolution Before File Access ('Link Following') vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Elevation of Privileges.

AnalysisAI

Local privilege escalation in Dell Command Update (DCU) versions prior to 5.7.1 allows a low-privileged local attacker to elevate their access by exploiting improper symbolic or hard link resolution (CWE-59) during DCU's file operations. Because DCU routinely executes with elevated system privileges to install drivers and firmware, an attacker who can plant a crafted link at a path DCU resolves can redirect those privileged file operations to arbitrary protected locations, achieving integrity impact rated High. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog; Dell has released a fix in version 5.7.1 via advisory DSA-2026-309.
