CVE-2026-33642

CVE-2026-33642 affects Kitty up to version 0.46.2. The issue arises in handle_compose_command() in kitty/graphics.c, where 32-bit unsigned arithmetic for composition offsets can wrap and enable a heap buffer over-read/over-write. An attacker who can emit output to a Kitty terminal (e.g., maliciou...
