Unauthenticated code execution via usecmap type confusion
Published Feb 3, 2026 · Updated Feb 3, 2026
Type confusion in the PostScript interpreter in Lexmark device firmware allows remote attackers to execute code as an unprivileged user. The usecmap method inadequately validates user-supplied data, causing the interpreter to operate on it as an incompatible type. No authentication is required; network-adjacent access is sufficient, and successful exploitation runs code in the pagemaker user context.
