CVE-2026-22190Public exploit

Local stack disclosure via glyph-pattern format string

Published Jan 7, 2026 · Updated Jan 7, 2026

Uncontrolled format string handling in Panda3D egg-mkfont 1.10.16 and earlier allows local users to disclose stack memory via -gp. The glyph-pattern option becomes sprintf()'s format string with one character argument, so extra specifiers consume unintended stack values. Local command execution and a crafted font-generation invocation are required; leaked values are written into generated .egg and .png output.
