CVE-2025-26507Network attack vector

Unauthenticated service interruption via PostScript buffer overflow

Published Feb 14, 2025 · Updated Feb 14, 2025

Stack-based buffer overflow in HP LaserJet printer firmware allows remote attackers to interrupt service via a PostScript print job. HP identifies the faulty locus only as PostScript job processing and does not disclose the buffer, routine, or overwrite operation. No authentication or user interaction is required, but exploitation requires high complexity and specific conditions; the cited impact is limited to printer availability.
