In the Linux kernel, the following vulnerability has been resolved:

platform/x86: dell-wmi-sysman: Don't hex dump plaintext password data

set_new_password() hex dumps the entire buffer, which contains plaintext
password data, including current and new passwords. Remove the hex dump
to avoid leaking credentials.

AI Analysis

Impact

In the Linux kernel, a flaw in the Dell WMI Sysman driver causes the set_new_password() routine to hex‑dump the entire password buffer, exposing plaintext current and new passwords. This demonstrates an insecure handling of sensitive credential data (CWE‑256) that could allow an attacker to retrieve user passwords through the kernel's debug output.

Affected Systems

The vulnerability affects the Linux kernel across all platforms where the Dell WMI Sysman driver is compiled. No specific kernel releases are enumerated, so it applies broadly to any install of the affected driver.

Risk and Exploitability

The CVSS score of 5.5 indicates a moderate severity, and the EPSS score of less than 1% suggests the likelihood of exploitation is low. The CVE is not listed in the CISA Known Exploited Vulnerabilities catalog. Exploitation would require local access to the system with sufficient privileges to trigger the set_new_password() routine, likely through a WMI interface on Dell hardware. The attack vector is inferred as local privilege escalation rather than remote exploitation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the Linux kernel to a version that removes the hex dump in set_new_password().
  • Disable or unload the Dell WMI Sysman driver if not required for system operation.
  • Configure system safeguards (e.g., SELinux or AppArmor policies) to restrict Dell WMI Sysman driver usage to privileged users only.
