Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A low privileged user can set the date of the devices to the 19th of January 2038 an therefore exceed the 32-Bit time limit. This causes some functions to work unexpected or stop working at all. Both during runtime and after a restart.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A low-privileged user can set the device date to January 19, 2038, which exceeds the maximum value storable in a 32-bit signed integer (the Year 2038 problem). This causes time-dependent functions to fail or behave unexpectedly both during runtime and after system restart.

MitigationRestrict date/time configuration permissions to privileged users only, and migrate the system to use 64-bit time_t to prevent overflow.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify user permissions for date/time changes
    Review system configuration files (e.g., /etc/timezone, /etc/systemd/system/timesyncd.service, or vendor-specific config) and check if low-privileged users or groups have write access to time-setting utilities (ntpdate, timedatectl, date command with sudo, or vendor-specific time set APIs)
    Affected if Low-privileged users (non-root or non-admin) can execute commands or access APIs that modify system date and time
  2. Determine system time_t architecture
    On Linux/Unix systems, run 'getconf _TIME_T' or 'arch' to check if the system uses 32-bit time_t; alternatively, check kernel architecture with 'uname -m' - 32-bit systems (i686, i386) typically use 32-bit time_t
    Affected if System uses 32-bit time_t (typically 32-bit operating systems or older 64-bit systems without 64-bit time support)
  3. Verify time-related service configuration
    Inspect time synchronization services (ntp, chrony, systemd-timesyncd) and date/time setting daemons for permission settings; check ACLs or SELinux policies governing time configuration
    Affected if Time services allow configuration changes by unprivileged users or lack proper access controls
  4. Test if date can be set to 2038
    As a low-privileged user, attempt to set the system date to 2038-01-19 or later using available time-setting interfaces (date command via sudo, web UI, API, or CLI tool); observe if the operation succeeds
    Affected if Low-privileged user can successfully set the date to January 19, 2038 or later

A user is affected if low-privileged accounts can set the system date to values beyond January 19, 2038 on a system using 32-bit time_t.
