# CVE-2026-89444

## Summary

- **CVE ID:** CVE-2026-89444
- **Severity:** UNKNOWN
- **CVSS Score:** 1.51
- **CWE:** N/A
- **Published:** Sep 11, 2026
- **Last Modified:** Sep 16, 2026

## Description

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

platform/x86: dell-wmi-sysman: Don't hex dump attribute security buffer

set_attribute() populates the security area of the BIOS attribute request
buffer with the current admin password via populate_security_buffer(), then
dumps the whole request buffer with print_hex_dump_bytes(). This can expose
the plaintext admin password in the kernel log.

The same issue was fixed for the password attribute path by
commit d1a196e0a6dc ("platform/x86: dell-wmi-sysman: Don't hex dump
plaintext password data"). Remove the remaining dump from the BIOS
attribute path.
