Driver Pack For Windows OS: Uncontrolled Search Path Element
CVE-2026-56795 is a high-severity uncontrolled search path element vulnerability in Driver Pack For Windows OS from Dell, with a CVSS 3.1 base score of 8.2 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 26.07.01 as the first without the flaw, so updating Driver Pack For Windows OS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.19% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Driver Pack For Windows OS to 26.07.01 or a later version.
- Update Driver Pack For Linux OS to 26.07.01 or a later version.
- Update Server Update Utility, Windows 64-bit format to 26.07.01 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
Dell Server Update Utility, versions prior to 26.07.01, contains an Uncontrolled Search Path Element vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Code execution.

The underlying weakness: Uncontrolled Search Path Element
The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
How developers prevent this class of flaw
- Hard-code the search path to a set of known-safe values (such as system directories), or only allow them to be specified by the administrator in a configuration file. Do not allow these settings to be modified by an external party. Be careful to avoid related weaknesses such as CWE-426 and CWE-428.
- When invoking other programs, specify those programs using fully-qualified pathnames. While this is an effective approach, code that uses fully-qualified pathnames might not be portable to other systems that do not use the same pathnames. The portability can be improved by locating the full-qualified paths in a centralized, easily-modifiable location within the source code, and having the code refer to these paths.
- Remove or restrict all environment settings before invoking other programs. This includes the PATH environment variable, LD_LIBRARY_PATH, and other settings that identify the location of code libraries, and any application-specific search paths.
