CVE-2025-65081
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 · uneditedAn out-of-bounds read vulnerability has been identified in the Postscript interpreter in various Lexmark devices. This vulnerability can be leveraged by an attacker to execute arbitrary code as an unprivileged user.
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 confidenceAn out-of-bounds read vulnerability exists in the PostScript interpreter of Lexmark devices. This memory safety flaw allows a remote attacker to read beyond allocated buffer boundaries, which can be chained to achieve arbitrary code execution as an unprivileged user.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify Lexmark device model and firmware versionAccess the printer web interface or print a configuration/status page. Locate the device model name and firmware version displayed in the device information or system settings.Affected if The device is a Lexmark printer and the installed firmware version has not been updated to include the CVE-2025-65081 patch. Without specific version ranges, assume any unpatched Lexmark device with PostScript capability may be affected.
-
Verify PostScript interpreter is enabledIn the printer web interface, navigate to Settings > Print Settings > PCL/PostScript Emulation, or check the menus for PostScript configuration. Confirm whether PostScript is listed as enabled or available.Affected if PostScript is enabled or available on the device. The vulnerability exists in the PostScript interpreter, so a device with PostScript disabled has reduced exposure but may still be vulnerable if the interpreter code is present.
-
Determine network accessibility of printer management interfaceReview network configuration or firewall rules to check whether the printer web interface (ports 80/443) or print ports are reachable from untrusted network segments.Affected if The printer management or print interface is exposed to untrusted network segments, allowing remote attackers to send malicious PostScript jobs to the device.
The environment is affected if it is a Lexmark device with PostScript enabled, the firmware has not been patched for CVE-2025-65081, and the printer is accessible from a network where an attacker could send malicious PostScript data.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply vendor-supplied firmware updates for affected Lexmark devices; restrict network access to printer management interfaces to minimize attack surface.
