Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.81% for the current model date.

Compensating controls

  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Canon Inc. Generic Plus PCL6 Printer Driver and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

Out-of-bounds vulnerability in EMF Recode processing of Generic Plus PCL6 Printer Driver / Generic Plus UFR II Printer Driver / Generic Plus LIPS4 Printer Driver / Generic Plus LIPSLX Printer Driver / Generic Plus PS Printer Driver / Generic FAX Printer Driver / UFRII LT Printer Driver / CARPS2 Printer Driver / PDF Driver / LIPS4 Printer Driver / LIPSLX Printer Driver / UFR II Printer Driver / PS Printer Driver / PCL6 Printer Driver

What

Out-of-bounds vulnerability in EMF Recode processing of Generic Plus PCL6 Printer Driver / Generic Plus UFR II Printer Driver / Generic Plus LIPS4 Printer Driver / Generic Plus LIPSLX Printer Driver / Generic Plus PS Printer Driver / Generic FAX Printer Driver / UFRII LT Printer Driver / CARPS2 Printer Driver / PDF Driver / LIPS4 Printer Driver / LIPSLX Printer Driver / UFR II Printer Driver / PS Printer Driver / PCL6 Printer Driver

Why

A bounds error lets data be written beyond the intended memory region, potentially corrupting control data.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Out-of-bounds Write → cause the confidentiality, integrity or availability impact described by the vendor

CWE-787 ↗

CWE-787: Out-of-bounds Write. The product writes data past the end, or before the beginning, of the intended buffer.
