CVE-2026-58822Network attack vector

Unauthenticated code execution via improper FreeType casts

Published Sep 8, 2026 · Updated Sep 8, 2026

Incorrect type conversion in Android 14, 15, 16, 16-qpr2, and 17 allows remote attackers to execute code through FreeType font rendering. The ft_smooth_raster_lcd and ft_smooth_raster_lcdv functions in ftsmooth.c improperly cast values while rasterizing glyph outlines, creating a memory-unsafe state. No privileges or user interaction are required, and successful exploitation executes attacker-controlled code in the affected device context.
