CVE-2026-33642

A flaw was found in Kitty, a cross-platform GPU-based terminal. A remote attacker, by sending specially crafted escape sequences to a Kitty terminal, can exploit an integer wrapping vulnerability in the handlecomposecommand function. This vulnerability allows for out-of-bounds memory access, whic...

DEBIAN-CVE-2026-33642

Kitty is a cross-platform GPU based terminal. In versions 0.46.2 and below, the handlecomposecommand function in kitty/graphics.c performs bounds validation on composition offsets using unsigned 32-bit arithmetic that is subject to integer wrapping, potentially leading to Heap Buffer...

CVE-2026-33633

A flaw was found in Kitty, a cross-platform GPU based terminal. A remote attacker, by sending a specially crafted APC graphics protocol command with a large PNG payload to the terminal's standard input stdin, could trigger a heap buffer overflow in the loadimagedata function. This vulnerability...

CVE-2026-33633

Kitty is a cross-platform GPU based terminal. Versions 0.46.2 and below contain a heap buffer overflow in loadimagedata that allows any process which can write to the terminal's stdin to crash kitty immediately. The vulnerability is triggered by a single APC graphics protocol command with a PNG...

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...
