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 type confusion vulnerability has been identified in the Postscript interpreter in various Lexmark devices. The vulnerability can be leveraged by an attacker to execute arbitrary code.

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 type confusion vulnerability exists in the PostScript interpreter of Lexmark devices. This vulnerability allows an attacker to potentially execute arbitrary code by manipulating PostScript jobs processed by the device.

MitigationApply available Lexmark firmware updates when released. Consider restricting PostScript job processing to trusted sources and monitoring for unusual printer behavior.

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. Confirm device is a Lexmark device
    Access the device web interface or check the physical label to verify the device manufacturer is Lexmark. This vulnerability only affects Lexmark devices.
    Affected if The device is not a Lexmark printer or multifunction device
  2. Identify the firmware version
    Access the Lexmark device web interface (typically via http://[device IP]/ or through the embedded web server), navigate to Settings > Firmware or similar, and record the installed firmware version number.
    Affected if The installed firmware version falls within an affected version range and has not been patched
  3. Verify PostScript interpreter is enabled
    Access the device settings via the web interface or control panel menu. Navigate to Print Settings > Emulations or Printer Setup and check if PostScript emulation is enabled. This is often labeled as 'PostScript', 'PS', or 'PostScript Emulation'.
    Affected if PostScript emulation is enabled and processing print jobs from untrusted sources
  4. Check for unusual PostScript job processing
    Review device event logs, print job logs, or syslog if configured. Look for failed or suspicious PostScript jobs that may indicate exploitation attempts or unusual processing behavior.
    Affected if There are logged PostScript jobs showing errors, unexpected behavior, or jobs from untrusted sources

A user is affected if they have a Lexmark device with an unpatched firmware version where PostScript emulation is enabled and processing jobs from potentially untrusted sources.
