Exposure of Private Information ('Privacy Violation') in Linux kernel - CVE-2026-23370

Published: March 25, 2026


Vulnerability identifier: #VU124468
CSH Severity: Low
CVSS v4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-23370
CWE-ID: CWE-359
Exploitation vector: Local access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a local user to disclose sensitive information.

The vulnerability exists due to improper output neutralization in the dell-wmi-sysman driver when handling password data. A local user can access kernel logs to disclose sensitive information.

The vulnerability specifically involves the logging of plaintext passwords via a hex dump in the set_new_password() function, which could expose current and new passwords.
