CVE-2025-26508Network attack vector

Remote code execution via PostScript out-of-bounds write

Published Feb 14, 2025 · Updated Feb 14, 2025

Out-of-bounds write in certain HP LaserJet printer firmware allows remote attackers to execute code via a crafted PostScript print job. The PostScript processor writes attacker-controlled print-job data outside an intended buffer, but HP has not disclosed the affected routine or boundary error. No authentication or user action is required, and successful exploitation executes code in the printer context and can elevate privileges.
